Replace the single cached CleverTap instance with a "default slot" plus a resolveInstance(accountId) lookup on Android and iOS. Calls without an accountId keep resolving the default account, so existing behavior does not change. An unknown accountId logs one clear warning and no-ops instead of failing silently. Listeners are wired exactly once per account. This is point 1 of the multi-instance design docs — the foundation the other points build on. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Add two bridge methods so an additional CleverTap account can be created
straight from JavaScript, without native app changes.
createInstance(config) builds a native instance from a cross-platform
config (region, proxy domains, identityKeys, logLevel, encryptionLevel,
encryptionInTransit, useCustomCleverTapId) and resolves {accountId}. It
rejects missing or empty accountId/accountToken on both platforms and is
idempotent for an already-existing account. On iOS the config's region
and proxy fields are constructor-only and cannot be combined: region is
applied and proxy settings are ignored with a warning; Android applies
both.
getDefaultAccountId() resolves the account id the default slot points
to, which the upcoming JS handle layer needs to route the top-level
CleverTap object's events.
Point 2 of the multi-instance design docs.

Establish the per-account dispatch pattern on two representative methods: add an optional trailing accountId to the spec, both Android arch shims, the shared impl and iOS, and change each native body's first line from the default-slot getter to resolveInstance(accountId). Calls without an accountId keep using the default account. The JS wrapper now passes the trailing argument explicitly (null = default account) because the old-architecture Android bridge throws on a missing trailing argument. callWithCallback gains an optional 4th parameter so callback methods keep the agreed order: callback first, then accountId. Point 3 of the multi-instance design docs; the remaining methods follow the same mechanical edit in points 6 and 7. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Make every native event self-describe which account fired it, so JS can route events to the right account handle. Replace the shared singleton listener/delegate with one small object per account (CleverTapListenerProxy class on Android, new CleverTapReactInstanceDelegate on iOS). Each stamps its account's REAL id into every payload under __ctAccountId — the default account included, so a handle for the default account's own id works too. The per-account objects are kept in strong registries because the native SDKs hold several listener slots weakly; the registries are marked LOAD-BEARING in comments. Make the early-event buffers account-aware: onEventListenerAdded gains a trailing accountId, and the buffers arm and flush per account. Without this, account B subscribing first would drain and silently drop account A's buffered events (for example the push tap that cold-started the app). Untagged payloads stay global and go live once any listener attaches. The 5-second discard safety valve is unchanged. On iOS, replayed pending events are now removed from the queue so a second listener cannot receive duplicates. Point 4 of the multi-instance design docs. JS-side routing (handles + demux) lands with point 5; until then payloads carry the tag visibly. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Add the JavaScript layer of multi-instance support.
CleverTap.createInstance(config) resolves with a frozen per-account
handle; CleverTap.getInstance(accountId) always returns a (memoized)
handle — never null, because the native SDKs can restore accounts from
persisted config. Handle methods forward their accountId as the trailing
native argument.
Route events through one central demux (Firebase-style sorting office):
a single native subscription per event name reads the __ctAccountId tag
and re-delivers the event under 'accountId::eventName'; each handle
subscribes to exactly its own key, so no handle wakes for another
account's events. Top-level CleverTap listeners follow the default slot,
learned once via getDefaultAccountId and updated by
setInstanceWithAccountId. Handlers receive a sanitized copy without the
internal tag; the shared payload is never mutated. The native buffered-
event flush for the top-level object is armed only after the default
account id is known, so early events cannot be misrouted.
addListener now returns a {remove} subscription. removeListener removes
only listeners added through the same object (no more killing every
listener for the event name). setInstanceWithAccountId is marked
deprecated, pointing to getInstance/createInstance.
Point 5 of the multi-instance design docs.

Complete the first demoable slice: route onUserLogin and profileSet by accountId (spec, both Android shims, impl, iOS), expose both on the account handle, and extend the CleverTapInstance type. Add a "Multi Instance" section to the Example app: create account B from JS with a per-account CleverTapProfileDidInitialize listener, then recordEvent / onUserLogin / profileSet / getCleverTapID on account B, plus the unknown-account edge case, which must log one native warning and never crash. The main account's demos stay unchanged for regression comparison. Point 6 of the multi-instance design docs. Remaining ~95 methods follow in point 7 with the same mechanical edit.

Make every step of the per-account event journey observable, so a dropped event can be located from logs alone: JS logs (dev builds only) for default-account resolution, listener registration, flush arming, and each routing decision including drops; native logs for arming, per- account buffering/flushing with sent/kept counts, and the resolved account in onEventListenerAdded and getDefaultAccountId. Also stop silently swallowing a getDefaultAccountId failure — without that id no default-account event can be routed, so it now logs a loud warning instead. Verified on device: events tagged with the real account id are delivered to top-level listeners end to end. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The SDK is symlinked into the Example app from the wrapper repo root, and the root has its own node_modules (react-native 0.71.19, installed for lint). Metro resolved the SDK's `import ... from 'react-native'` to that copy, putting a second react-native into the bundle. Everything worked except events: native emits on the app copy's DeviceEventEmitter while the SDK listened on the other copy's, so listeners never fired. Block the wrapper root's node_modules from Metro resolution (the SDK has no runtime dependencies) and pin react/react-native to the Example's copies. Verified: the bundle now contains exactly one react-native. Only affects the Example/dev setup — customer apps install the SDK into their own node_modules and never had two copies.

On device, a single createInstance click constructed TWO CleverTapAPI
objects for the same account ("CleverTap SDK initialized" logged twice,
different object hashes, different threads). Root cause is in the native
Android SDK: DeviceInfo posts a deviceIDCreated callback to the main
thread that re-enters instanceWithConfig, and the static instances map
has no lock — so a creation running on the native-modules thread races
that callback, the map keeps the callback's copy, and the bridge's
listeners stay attached to an orphaned instance.
Run the creation on the main thread instead: the SDK's callback is also
main-posted, so the two are serialized and the re-entrant call finds the
already-registered instance. Make initedAccountIds a synchronized set
since it is now touched from two threads. iOS needs no change — the
module's methodQueue is already the main queue.
The missing synchronization should also be fixed in the native Android
SDK (to be reported separately).

Apply the trailing-accountId pattern to the remaining 92 public methods across all layers: TurboModule spec, both Android arch shims, the shared impl (with product-config/inbox helpers threaded through so those methods genuinely route), the iOS bridge, the JS top-level wrappers (explicit trailing null — old-architecture Android throws on a missing trailing argument), the account-handle proxies, and the CleverTapInstance type. An account handle now behaves like the top-level CleverTap object for the whole API surface. Tag the remaining per-account events with the REAL account id: the variables callbacks on both platforms, and the iOS inbox events (init/update from the registration callback; message taps stamped with the account whose inbox is presented, tracked when showInbox presents it) — Android inbox events were already tagged via the listener proxy. OS-level methods (push registration/permission, notification channels, createNotification, getInitialUrl) stay default-account-only: the handle exposes them as warn-and-no-op stubs. Custom templates and setDebugLevel are global by design and are not on the handle. setPushTokenAsStringWithRegion is a dead legacy method (no-op on every platform, not exposed on the top-level object) — it stays off the handle and the CleverTapInstance type; it only gains an old-arch Android stub for arch symmetry with the new-arch one. Verified: Android new-arch (codegen) and OLD-arch compiles, iOS build, Metro bundle, tsc on the types, zero new lint errors, and a scripted cross-layer audit in all six files. Point 7 of the multi-instance design docs. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The bridge kept ALL variables in one name-keyed registry (a static map on Android, allVariables on iOS). With two accounts, a same-named variable defined by account B overwrote account A's entry: reads returned the last writer's value, getVariables returned every account's variables merged, and onValueChanged could attach account A's listener to account B's variable while stamping the event with A's id — silent cross-account data leaks. The native SDKs were never the problem: variables are per-instance there. Restructure both registries as per-account buckets keyed by the REAL account id, then by variable name. Every read, write, listener attachment, and variables-changed payload now uses only the owning account's bucket. Thread safety is mandatory here and documented on both declarations: bridge methods run off the main thread on Android while createInstance runs on main and the SDK fires variable callbacks on its own threads — Android uses ConcurrentHashMap on both levels (with null-guards, since it rejects null keys/values); iOS guards every registry access with @synchronized because SDK callbacks run off the module's main queue. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
ConcurrentHashMap throws NullPointerException on null keys even for READS (get/containsKey), unlike the HashMap it replaced which quietly returned false — verified against the official Java documentation. A JS caller passing a null variable name would previously get the graceful "does not exist" path and would now crash. Guard every path where a caller-supplied name can reach the registry: getVariableValue / getVariableValueAsWritableMap take the "does not exist" path on null names; onValueChanged / onFileValueChanged log the existing error instead of throwing; defineFileVariable rejects a null name before it can reach the registry or the native SDK. Also guard defineVariables against a null variables object (the spec allows null; iOS already had this guard, Android did not). Full trace of both registries re-audited: Android's outer map has a single entry point (atomic computeIfAbsent with a pure, short mapping function), both levels are ConcurrentHashMap with per-key happens-before on reads, and iteration is weakly consistent (never throws ConcurrentModificationException). iOS accesses the registry only inside @synchronized on a lock object that is assigned once and never replaced. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Harden the iOS variables registry against a theoretical lock-order inversion: getVariableValuesForInstance read each CTVar's value while holding our @synchronized lock. If a future SDK version ever synchronized that getter internally while its callback threads call back into us (which take our lock), two threads could deadlock — and a deadlocked main queue is an app hang. Snapshot the registry under the lock and read the values outside it; the define paths already made their SDK calls outside the lock. Result of the full ANR/deadlock permutation audit: no user code, I/O, or SDK call ever runs under any of our locks on either platform; ConcurrentHashMap reads never block and its one blocking case (computeIfAbsent) runs only a pure allocation.

Reported by the BeardedRobot-RN test app: every callback-taking method
crashed on old-architecture Android with "Invariant Violation: Cannot
have a non-function arg after a function arg." — a hard crash in release
builds too. React Native's old-arch bridge reads callbacks off the END
of the argument list (NativeModules.js) and throws if anything follows a
function; our trailing accountId came after the callback. The new
architecture does not run this check, which is why compiles and new-arch
device testing never caught it: old-arch must be smoke-tested at
runtime, not just compiled.
Reorder all 37 callback methods so the callback is the LAST argument and
accountId comes before it — consistently in every layer: the JS helper
(callWithCallback now inserts accountId before the callback), the
TurboModule spec, both Android arch shims, the shared impl, and the iOS
selectors. Public JS signatures are unchanged. The impl was aligned to
the same order so no layer swaps arguments at call sites; the swap is
compiler-checked (Callback vs String types).
Also fix syncVariablesinProd: the old-arch shim declared a phantom
callback parameter that no other layer has — a pre-existing arity
mismatch that also crashes RELEASED SDK versions on old-arch Android
("got 1 arguments, expected 2"); codegen cannot catch old-arch drift
because that shim has no build-time link to the spec. The impl's dead
callback parameter is removed.
Verified: Android new-arch (fresh codegen) and old-arch compiles, iOS
pod re-codegen + build, Metro bundle, tsc, zero new lint errors, and a
scripted audit that the callback is last in all 37 methods across all
four declaration layers plus the JS helper.

Add the remaining common per-instance options, verified exhaustively against the pinned native sources (clevertap-android-sdk corev8.4.1, CleverTap-iOS-SDK 7.8.1): handshakeDomain, analyticsOnly, enablePersonalization, disableAppLaunchedEvent, and the 'high' encryption tier (both SDKs support three at-rest levels, we exposed two). Also fix a real footgun: useCustomCleverTapId could be set from JS but the custom CleverTap ID itself could not be supplied — both platforms accept it only at creation time, so such an instance would wait forever for an ID and end up with an error device id. createInstance now accepts cleverTapId and passes it to instanceWithConfig at creation. Document the identityKeys asymmetry in the type: it applies to accounts created from JS; the default account takes identity keys only from AndroidManifest.xml / Info.plist (both native SDKs ignore the setter on the default instance). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Expose the remaining per-instance native options under nested platform
blocks: android { useGoogleAdId, backgroundSync, pushProviders } and
ios { disableIDFV, enableFileProtection }. Each platform reads only its
own block and ignores the other's, so platform-targeted config needs no
cross-platform warnings, and the TypeScript type itself documents which
platform owns each option.
pushProviders entries mirror the native PushType contract (type,
prefKey, className, messagingSDKClassName — the same four parts as the
manifest CLEVERTAP_PROVIDER keys); entries missing any part are skipped
with a warning naming the index, never silently dropped.
With this the React Native createInstance config covers the ENTIRE
per-instance configuration surface of both native SDKs, verified
exhaustively against clevertap-android-sdk corev8.4.1 and
CleverTap-iOS-SDK 7.8.1. Deliberate exclusions, all with reasons:
cryptManager (SDK-managed), beta (vestigial), SSL pinning (no runtime
API), and manifest/plist-only process-wide keys (set in the host app as
always; several auto-seed JS-created instances natively).

Custom template events (CleverTapCustomTemplatePresent, Close, CustomFunctionPresent) deliver the template name as a bare string on both platforms. routeEvent ran "CT_ACCOUNT_ID_KEY in event" on that string, and the JS 'in' operator throws TypeError on primitives — so any presented custom template crashed the app (RedBox in dev, fatal in release). Regression introduced with the demux; released SDKs passed the string straight to listeners. Treat non-object payloads as untagged: they cannot carry an account tag, so they route to the top-level listeners exactly like before the demux existed. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The native SDKs already scope custom templates per instance: every
CleverTapAPI/CleverTap instance runs the registered producers with its
own config and keeps its own active contexts. The wrapper was wired to
the default slot only, so a template presented by a secondary account
could never be read or dismissed from JS — blocking that account's
entire in-app queue.
Register a per-account producer instead of one shared presenter: each
instance (the default and every JS-created account) gets the same JSON
definitions wired to presenters that stamp its real account id. Tag
template events without changing their public shape — the template
name string travels wrapped ({__ctAccountId, __ctPayload}) and the JS
demux unwraps it, so handlers keep receiving the bare string.
Route the nine customTemplate* methods plus syncCustomTemplates and
syncCustomTemplatesInProd by a trailing accountId (placed BEFORE the
promise — the promise must stay the last argument on the old-arch
bridge) and expose all of them on account handles.
Guard instanceWithConfig in createInstance with try/catch on both
platforms: template producers run inside it and duplicate template
names throw, which would otherwise crash the app on the main thread
instead of rejecting the promise.
Add an Example app action that listens for account B's template
presents, reads an argument and dismisses via the handle.

The bridge called the CLASS method [CleverTap setLocation:], which the iOS SDK hardwires to [CleverTap sharedInstance] — the plist account. So a handle's setLocation silently set the location on the wrong account, and even the top-level call ignored a swapped default slot. Android already routed per instance. Use the SDK's per-instance setter (-setLocation:, verified at CleverTap-iOS-SDK 7.8.1) on the resolved instance. Unknown accounts warn once in resolveInstance and no-op via nil messaging, matching every other routed method. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Production crash (SDK-6021, Ooredoo Tunisia): NoSuchElementException at LinkedList.removeFirst. flushBuffer drained under the buffer lock, but emit -> addToBuffer wrote with NO lock. Emits arrive on the SDK's callback threads (variable callbacks on main via runOnUiThread; profileDidInitialize synchronously on SDK executors; even the bridge thread when addVariablesChangedCallback fires immediately) while arm/flush runs on the NativeModules thread — an unguarded LinkedList mutated cross-thread. The v3.2.0 fix (SDK-4375) only synchronized the drain, so every release since still crashes. Guard ALL buffer state — items, armed accounts and the enabled flag — with one monitor per buffer, and make the buffer-or-send decision a single atomic offer(): a separate check-then-add let a payload slip in AFTER its account's flush and be silently discarded at the 5s reset. Keep the buffers map immutable instead of swapping it (a racing emit could buffer into the discarded copy), send events strictly OUTSIDE the lock (never invoke React Native under a monitor), and mark reactContext volatile. Add JVM tests: a 50k-payload race test that reproduces the exact production exception on the unfixed code and asserts every payload is delivered exactly once, plus per-account keep/flush, arm, discard, non-bufferable and null-payload semantics. junit + returnDefaultValues added to the library build for unit testing.

The static pending-event queue (pendingEvents, observedEvents, observableEvents, isObserving) was mutated from two threads with no protection: onEventListenerAdded, startObserving and the 5s cleanup run on main (methodQueue), but SDK callbacks post through sendEventOnObserving from elsewhere — profileDidInitialize is dispatched on a global background queue (verified at CleverTap-iOS-SDK 7.8.1, CleverTap.m) and the push-tap delegate runs on its caller's thread. NSMutableDictionary/NSMutableSet are not thread-safe, so a cold-start callback racing the first JS addListener could crash (collection mutated while enumerated) or silently lose a queued event via the check-then-create of an event's pending array. Same defect class and startup window as SDK-6021 on Android. Hop to the main queue at the top of sendEventOnObserving when called off-main, making every reader and writer of the queue state main-confined. An async hop instead of a lock on purpose: delivery is already asynchronous, the serial main queue preserves per-account ordering, and no new lock means nothing new the main thread could ever block on. Bonus: notification posts (and RCTEventEmitter sends) now always happen on main. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
sLaunchUri is written on the main thread (CleverTapRnAPI.setInitialUri at launch) and read on the bridge thread (getInitialUrl). Without volatile the reading thread may never see the write and JS gets "InitialUrl is null" although the app WAS launched from a deep link — a silently lost navigation, no crash, no log. Mark it volatile and document the reasoning inline for future readers. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
mDefaultCleverTap is touched from more than one thread over the module's life: the constructor resolves it on the module-init thread, bridge methods read and swap it on the NativeModules thread, and createInstance runs on main. Without volatile a thread may keep seeing a stale pointer after setInstanceWithAccountId swapped it and silently route calls to the OLD account. Mark it volatile; the lazy init's check-then-act stays benign because getDefaultInstance returns the same SDK-managed singleton on every call. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
attach() is reachable from the host app's launch init (main thread) and the module's own init (bridge thread). Its unregister+register pair is not atomic: two overlapping calls could both unregister first and then both register, leaving the proxy in the SDK's push-permission listener list twice — one permission-dialog tap would fire two identical events to JS. Guard attach() with the per-proxy monitor; it protects only quick listener-slot assignments (no I/O, no callbacks), so nothing can block on it noticeably. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
deliverRouted invoked every handler of a routed key in a bare forEach: the first handler that threw stopped delivery to the remaining handlers of that event AND skipped the default-slot mirror, with the error bubbling into the native event emitter. One module's buggy listener silently ate another module's events. Guard each handler call individually — log the throw loudly, keep delivering. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…backs getInstance(null/undefined/''/non-string) built the worst possible handle: its calls silently routed to the DEFAULT account (null means default natively) while its listeners subscribed to a dead routing key like "null::eventName" that no event ever matches — wrong-account data AND vanished events, no trace. Now an invalid accountId logs a loud error and returns the DEFAULT account's handle, so calls and listeners behave as one consistent, stated thing. The two callback-taking warn-stubs on handles (isPushPermissionGranted, getInitialUrl) warned but never invoked the callback, hanging any caller that awaited them. They now also complete the callback with a clear error. index.d.ts updated to match. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Handles exposed addListener/removeListener but not addOneTimeListener — an accidental parity gap found while auditing the full API surface (the concept is perfectly per-account; the handle's own variables one-time callbacks already use the same self-removing pattern internally). Add it mirroring the top-level behavior: the handler fires once, for the first matching event of this handle's account, then detaches itself. index.d.ts updated with the signature. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The wrapper pre-checked existence with getGlobalInstance before creating — but that call is not a pure read: on a fresh app launch it RESURRECTS the instance from the config persisted on a previous launch (Android reads the "instance:<id>" prefs, iOS unarchives the config file, both only when the in-memory map is empty). The resurrected stale instance then made the wrapper declare "already exists; config ignored", so a config passed on launch 2+ was never applied — an app fetching its CleverTap config from a server on every launch could never change region, encryption or identity keys. Drop the pre-check and call instanceWithConfig directly, restoring the exact native contract (verified at corev8.4.1:918-943 and iOS 7.8.1 CleverTap.m:457-477): fresh launch -> the passed config is applied AND persisted; repeat call in the SAME app run -> the native SDK returns the existing instance and keeps the original config (its in-process idempotency, silent like native). This also restores native's error-device-id repair branch for existing instances with a custom cleverTapId, which the early-return bypassed. Deferred to a next release: an RN-level repeat-call warning (via our own initedAccountIds, no core coupling) and a native-SDK request for a default-visible "config not applied" log. JSDoc/d.ts updated with the two-case semantics. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The seven notification-channel methods required the DEFAULT (manifest) instance to exist and returned silently otherwise — breaking channels for apps that create their CleverTap instances from JS instead of the manifest. The guard was redundant: the native statics resolve an instance themselves via getDefaultInstanceOrFirstOther (default, else the first created account) and only borrow its executor and logger — the real work is a plain NotificationManager call (verified at corev8.4.1:357-694). Drop the instance guard, warn on null arguments instead of silently returning, and add warnIfNoInstanceExistsYet: native's own "no instance found" log is verbose-gated, so a channel call made before the first createInstance would otherwise vanish without a trace. The check uses only this module's own state (mDefaultCleverTap + initedAccountIds) — no CleverTap core internals. Success logs now say "requested" since the outcome belongs to the native SDK. Impl-body-only change: no signatures touched, handles keep their warn-stubs, iOS unchanged (channels are no-ops there). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
createNotification required the DEFAULT (manifest) instance and returned silently without it — but the caller's account was never relevant: the native static reads wzrk_acct_id from the payload and routes rendering plus the Notification Viewed event to THAT account's instance, restoring it from persisted config on a cold process (verified at corev8.4.1:283-338, 1027-1030). The guard silently broke push rendering for apps that create their instances from JS. Drop the guard and fix two failure-visibility holes on the way: null extras previously reached jsonObjectFromReadableMap and crashed with an uncaught NullPointerException (the catch only covers JSONException) — now warned and ignored; and the JSON parse failure now logs its consequence instead of e.printStackTrace(). warnIfNoInstanceExistsYet covers the zero-instances window with module-local state only. Impl-body-only change: no signatures touched, handle stub unchanged, iOS unchanged (createNotification is a no-op there). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
promptForPushPermission, promptPushPrimer and isPushPermissionGranted were warn-stubs on handles and hardwired to the default slot — the one deviation from the branch's own routing rule, since natively all three are ordinary INSTANCE methods. The account genuinely matters for the response path: PushPermissionHandler is built per instance and the permission result notifies only the PROMPTING instance's listeners (verified at corev8.4.1, CleverTapFactory.kt:238, PushPermissionHandler.kt:150-176). So handleB.promptForPushPermission now shows the app-wide system dialog and the CleverTapPushPermissionResponseReceived event fires on handleB's listeners. This also gives manifest-less apps (no default account) a first-class path to request push permission. Add the trailing accountId across spec, both Android shims, impl and iOS (callback stays last on isPushPermissionGranted — old-arch rule). Fix a hang on the way: iOS isPushPermissionGranted messaged nil when no instance existed, silently swallowing the completion handler so the JS callback never fired; it now completes with an error, as does the unreachable pre-iOS-10 branch. Handles swap their three stubs for real calls; the permission itself remains app-wide (documented). Direct NativeModules callers of these three methods break on old-arch Android (argument count) — same blanket CHANGELOG warning, three more names on its list and on the old-arch runtime smoke-test list.

setCustomSdkVersion was applied only to the default instance via the import-time setLibrary call; instances wired later (createInstance, getInstance calls, slot swaps) got the library name but no version, so secondary accounts under-reported the wrapper version — and in an app with no manifest/plist account the version was lost entirely (there was no default instance to stamp at import time). Remember name+version from setLibrary (volatile fields on Android, main-queue-confined properties on iOS) and stamp them at the wire-once choke point every instance passes through exactly once (Android initCtInstance, iOS resolveInstance's wiring block), regardless of which path wired it. The direct call inside setLibrary stays: on Android the default is wired in the module CONSTRUCTOR, before JS has provided the version, so setLibrary's direct call is the only path that versions the default; on iOS it is belt-and-suspenders against future ordering changes. iOS createInstance's own setLibrary line is removed — the wire-once block is the single owner.

An account created from JS only exists once the JS bundle runs (~2s into a cold start), so events firing before that - most importantly the push tap that launched the app - were lost for it. The host can now pass the accounts that need launch-time protection: - Android: initReactNativeIntegration(context, launchConfigs) creates each CleverTapLaunchConfig (config + optional custom CleverTap ID) and attaches the listener proxy before any Activity runs. Existing callers keep compiling via JvmOverloads. CleverTapApplication exposes an overridable launchConfigs() hook. - iOS: applicationDidLaunchWithOptions:launchConfigs: creates the listed accounts inside didFinishLaunchingWithOptions, before the launch notification hands out the launch push payload. - Creation stays on the MAIN thread on purpose: instanceWithConfig has an unlocked registry and (Android) a device-ID callback that re-enters it on the main thread - background creation can build two instances of one account and can miss the very launch events this API exists for. - Per-account try/catch: one bad config warns and is skipped, never blocking launch or the remaining accounts. A cleverTapID passed without enableCustomCleverTapId warns instead of being silently ignored. - JS pairing rule documented on getInstance: launch-listed accounts use getInstance(accountId) (the native config is the single source of truth); all other accounts keep createInstance as their first touch. - Example apps carry a commented usage block; active configs would stop the createInstance demos from exercising the fresh-config path.

drainFor rebuilt the queue through a temporary kept list and copied it back on every flush. Now matching payloads are unhooked in place with the iterator (O(1) per removal on a LinkedList) and the other accounts' payloads never move. The result list is pre-sized to items.size - the worst case where every payload matches - so it never regrows; the size read is stable because the whole method holds the buffer's monitor. Behavior is unchanged (order preserved for sent and kept payloads); the 50k-iteration emitter race test still passes. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

@nishant-clevertap Yes, it runs whenever the app has no default account. [CleverTap sharedInstance] returns nil when Info.plist has no CleverTapAccountID / CleverTapToken (first check in _sharedInstanceWithCleverTapID:, CleverTap.m, SDK 7.8.1). That is a supported setup with multi-instance: an app that creates all its accounts from JS via createInstance and has nothing in the plist. If such an app calls a top-level method like CleverTap.recordEvent(...), the default slot resolves to nil, this warning prints, and the call is dropped — without it the drop would be silent. Same as Android's getDefaultInstance() returning null without manifest credentials.
Where this lives in the history: the branch was added with resolveInstance: in 980ab24, and as of 68ff7d9 every caller reacts to that nil through the withInstance:run: / withInstance:callback:run: helpers (drop the call, or complete the JS callback with an error).

what if useCustomCleverTapId is not provided in config and cleverTapId is provided?
Contributor

There was a problem hiding this comment.
@nishant-clevertap Checked what both native SDKs actually do in that case (iOS 7.8.1 CTDeviceInfo.m line 187, Android 8.4.1 DeviceInfo.java line 928): the ID is silently ignored — the SDK logs "CleverTapUseCustomId has not been specified…", records a validation error and generates its own id. So the developer's cleverTapId is lost and every event lands under the wrong user, with no signal on the JS side. The reverse (useCustomCleverTapId: true without an id) leaves the account on an "error device id". React Native also has no later repair path (native can still pass the id via onUserLogin(profile, cleverTapID); RN does not expose that).
Fixed in eaff751: createInstance now rejects with EINVALID unless cleverTapId and useCustomCleverTapId: true are given together (or both left out), on both platforms — same fail-fast rule as an empty accountId/accountToken. Typings and JSDoc document the pairing. The native launch-config paths keep their warning, since at launch there is no promise to reject.

Contributor

There was a problem hiding this comment.
@nishant-clevertap Confirmed, the template name reaches app code unchanged. The wrapper {__ctAccountId, __ctPayload: templateName} is internal to the native→JS wire: a bare string cannot carry the account tag, so native wraps it and the JS demux (routeEvent in src/index.js) unwraps __ctPayload before any handler runs. CleverTap.addListener(CleverTapCustomTemplatePresent, templateName => …) still receives the plain string exactly as documented in docs/CustomCodeTemplates.md, and the Example app relies on that. The line here only replays the same wrapped body into the same demux, so pending events are unwrapped too. Android does the identical wrap (CT_PAYLOAD_KEY in CleverTapCustomTemplates.kt). The only code that would notice is an app subscribing to the raw NativeEventEmitter directly, which is undocumented and already called out in the PR description. Introduced in 7d33160 (see routeEvent in that commit).

@nishant-clevertap Agreed that the bare null was unreadable. Instead of a comment at each of the ~110 call sites, 2640e59 introduces one named constant DEFAULT_ACCOUNT (= null, "address the default account") with a single comment explaining why it must always be passed (the old-architecture Android bridge checks the exact argument count). Every top-level call now reads CleverTapReact.setOffline(value, DEFAULT_ACCOUNT), and the handle path's toAccountArg uses the same constant, so there is one definition to maintain. No behavior change; eslint count and the Metro release bundle are unchanged.

@nishant-clevertap Good catch — I verified every resolveInstance: call site. Two findings:
1. No crash is possible. In Objective-C, calling a method on nil is a silent no-op (unlike Java's NullPointerException): the call is skipped, a number result is 0, an object result is nil. So [[self resolveInstance:accountId] setLocale:userLocale] with a missing account was already crash-safe.
2. But three methods DID have a real bug. fetchInApps:, fetchInboxWithCallback: and fetchVariables: take a completion block. Skipping the call skips the block, so the JS callback never fired and an awaiting caller hung forever (Android correctly answered with an error).
Fixed in 68ff7d9: every bridge method now goes through one of two helpers, so the missing-account rule lives in one place instead of ~90 call sites:
withInstance:run:— fire-and-forget methods; the call is dropped (the one warning is already logged byresolveInstance:).withInstance:callback:run:— callback methods; the callback is completed with"CleverTap is not initialized"(same as Android).

why accountId is not optional here and at some places below?
Contributor
Author
There was a problem hiding this comment.
@nishant-clevertap Fair question — the mix was forced by TypeScript, not intended. On the bridge a callback must be the LAST argument, so in getInboxMessageCount(accountId, callback) the accountId comes first, and TypeScript rejects an optional parameter before a required one (error TS1016: A required parameter cannot follow an optional parameter). That is why only the callback-free methods could carry ?.
The ? was misleading anyway: JS never omits the argument (top-level calls pass DEFAULT_ACCOUNT, handles pass toAccountArg(accountId)), because the old-architecture Android bridge checks the exact argument count and throws on a missing trailing argument.
5ee29ea gives every method the same, honest shape accountId: string | null (required, nullable) plus one comment on the interface with the rule. No native impact — I regenerated codegen on both platforms and the generated NativeCleverTapModuleSpec.java and iOS CTTurboModuleSpec are byte-identical to before.
CleverTapInstanceConfig, CleverTapInstance and CleverTapEventSubscription
appeared in exported signatures but were module-private, so consumers
could not name them - typing a stored handle, a config-building helper
or a subscription field forced Awaited<ReturnType<...>> workarounds.
They are now exported:
import type { CleverTapInstance } from 'clevertap-react-native';
Types only - no runtime change. Callback/CallbackString stay private on
purpose: callback parameters are contextually typed at the call site, so
consumers never need to name them.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
resolveInstance: returns nil for an unknown accountId (or when the app has
no plist account). Messaging nil is a silent no-op in Objective-C, so the
~90 direct `[[self resolveInstance:accountId] foo]` call sites could never
crash - but three of them pass a completion block into the SDK
(fetchInApps:, fetchInboxWithCallback:, fetchVariables:), and a skipped call
means a skipped block: the JS callback never fired and an awaiting caller
hung forever. The other callback methods answered 0 / null with no error,
unlike Android, which reports "not initialized".
Every bridge method now reaches its instance through one of two helpers:
- withInstance:run: fire-and-forget methods; drops the call
- withInstance:callback:run: callback methods; completes the callback
with kCleverTapNotInitializedError
so the "account is missing" rule is written once instead of implied at
every call site. The unused cleverTapInstance accessor is removed.
The four background-queue readers (getUserEventLog, getUserEventLogCount,
getUserEventLogHistory, getUserAppLaunchCount) now resolve the instance on
the main queue and capture it, instead of calling resolveInstance: - which
mutates main-confined state - from the global queue.
Behavior change for JS callers on iOS: a callback method addressed to a
missing account now receives err = "CleverTap is not initialized" (Android
parity) instead of a default 0 / null result.
Verified: Example iOS app compiles (xcodebuild, iphonesimulator).

…sagree
A custom CleverTap ID only takes effect together with useCustomCleverTapId.
Neither native SDK fails on a mismatch (verified in CleverTap-iOS-SDK 7.8.1
CTDeviceInfo.m and clevertap-android-sdk 8.4.1 DeviceInfo.java):
- cleverTapId given, flag missing -> the ID is IGNORED; the SDK generates
its own id and records USE_CUSTOM_ID_MISSING_IN_MANIFEST. The app's id
is lost and every event lands under the wrong user.
- flag true, cleverTapId missing -> the account is left on an "error
device id" (USE_CUSTOM_ID_FALLBACK).
Both only surface as a native debug log a React Native developer never
sees, and - unlike native, which can still pass the id via
onUserLogin(profile, cleverTapID) - RN has no way to repair the identity
later. createInstance therefore rejects with EINVALID unless cleverTapId
and useCustomCleverTapId: true are given together (or both left out), the
same fail-fast rule already used for an empty accountId / accountToken.
The reads are type-checked (a JS null arrives as ReadableType.Null / NSNull
and would throw on getBoolean / boolValue). The native launch-config paths
keep their existing warning: at app launch there is no promise to reject.
Typings and the JSDoc document the pairing rule.
Verified: Android module compiles on both architectures, Example iOS app
compiles, tsc on src/index.d.ts passes, eslint problem count unchanged.

…null
Every top-level CleverTap method passed a bare `null` as the trailing native
accountId ("address the default account"), ~110 times, with the reason
written down at exactly one of them. A reader could not tell what the null
meant, and a future cleanup that drops it would throw at runtime on the
old-architecture Android bridge, which checks the exact argument count.
The value now has a name: DEFAULT_ACCOUNT (= null), defined once with the
explanation, used at every top-level call site, and shared by the handle
path's toAccountArg so both paths have a single definition.
CleverTapReact.setOffline(value, null);
CleverTapReact.setOffline(value, DEFAULT_ACCOUNT);
No behavior change. The `args` null of callWithCallback is a different
parameter and is untouched.
Verified: eslint problem count unchanged, Metro release bundle builds.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The spec declared `accountId?: string | null` on the fire-and-forget methods and `accountId: string | null` on the callback methods. The mix was forced by TypeScript, not chosen: a callback must be the last argument on the bridge, and TS1016 forbids an optional parameter before a required one, so the callback methods could not use `?`. The `?` was also misleading. JS never omits the argument - the top-level object passes DEFAULT_ACCOUNT and handles pass toAccountArg(accountId) - because the old-architecture Android bridge checks the exact argument count and throws on a missing trailing argument. "Optional" promised something no caller may do. Every accountId is now `accountId: string | null` (required, nullable), with one comment on the interface stating the rule. The two nullable booleans that sit before an accountId (setOptOut's allowSystemEvents, discardInAppNotifications' dismissInAppIfVisible) follow the same rule as `boolean | null`, since TS1016 would otherwise reject the required accountId behind them. No native change: codegen emits the same nullable parameter for both spellings - the regenerated NativeCleverTapModuleSpec.java and the iOS CTTurboModuleSpec header/mm are byte-identical to the previous output. Verified: Android codegen + module compile (new arch), old-arch compile, iOS pod install + Example app build, tsc on the spec and typings. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
onEventListenerAdded armed an account and then flushed its buffer as two
separate locked steps. Between them, a same-account event arriving from the
SDK thread was already "armed" and went straight to React Native, ahead of
the older events still waiting in the buffer - JS could see an in-app
Dismissed before its Showed. Merging arm+drain under the lock was not
enough either: the drained list was sent after the lock was released, so a
live event could still slip in between.
Instead of a second lock held during sends, the emitter now shares nothing.
Every operation - emit, armAndFlush, resetAllBuffers - is posted to one
single-thread worker (Executors.newSingleThreadExecutor: sequential, FIFO,
submission happens-before execution) and runs there:
- no data race: only the worker touches a Buffer, so the Buffer class has
no synchronization at all (the SDK-6021 LinkedList crash class is gone
by construction, not by locking)
- no reorder: "decide whether to buffer" and "send" are one task, and a
flush sends its whole drained list in one task
- no deadlock: there is no lock to order; React Native is only ever
called from the worker, never under a lock
Callers never wait on the worker: execute() only enqueues (unbounded queue),
the thread is created lazily on the first task, and the only blocking call
(awaitIdle) is internal and test-only. The thread is a named daemon so an
idle worker cannot keep a plain JVM (unit tests) alive.
armAccount + flushBuffer are merged into armAndFlush, which
CleverTapModuleImpl.onEventListenerAdded now calls.
Tests: existing tests adapted to the async worker (awaitIdle before
asserting). New deliveredInEmitOrder_evenWhenListenerAttachesMidStream
replays the attach-mid-stream moment 300 times and asserts strict emit
order; run against the previous implementation it fails in both proof runs
("1 test completed, 1 failed"), on this one it passes. The 50k-iteration
SDK-6021 race test still passes.
Verified: JVM unit tests 7/7, Android module compiles on both architectures.

…old-arch shim The comment claimed the impl takes an unused callback and that the shim passes null for it. CleverTapModuleImpl.syncVariablesinProd(boolean, String) has no callback parameter and nothing passes null; the sentence described an earlier shape of the method. The comment now states what is true: the (isProduction, accountId) shape must match the spec because the old-arch bridge checks the exact argument count, and the call is a logged no-op on Android (no production/debug variant of variable sync natively; iOS honors isProduction). Comment-only change. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
enablePersonalization:/disablePersonalization: ignored accountId and called the CleverTap class methods. In CleverTap-iOS-SDK 7.8.1 those only persist a preference (kWR_KEY_PERSONALISATION_ENABLED) that is read ONCE, when the plist default config is first built; every getter then checks its own instance's `config.enablePersonalization` (profileGet:, eventGetFirstTime:, getUserEventLog:, ... 10 call sites in CleverTap.m). So the bridge methods never affected a secondary account, and did not affect the default account within the current run either - `CleverTap.disablePersonalization()` followed by `profileGetProperty` still returned the value until the next launch. Android's instance methods flip the instance config flag at once. The bridge now does the same on iOS: resolve the instance and set `instance.config.enablePersonalization` (the SDK copies the config once at init and reads that copy on every gated getter, verified in CleverTap.m). For the default slot the class method is still called, so the persisted preference - and therefore the next launch - behave exactly as before. Verified: Example iOS app compiles.

The four one-time wrappers (top-level addOneTimeListener, and the handle's addOneTimeListener, onOneTimeVariablesChanged and onceVariablesChangedAndNoDownloadsPending) called handler(event) first and subscription.remove() second. deliverRouted deliberately catches a throwing handler so the other listeners still receive the event - which also means the removal after the throw never ran, and the "once" wrapper fired again on the next event. The four copies are now one helper, addOneTimeListenerForHandle, which removes the subscription BEFORE invoking the handler. Return values are unchanged. Removing from the handler Set while deliverRouted iterates it is well-defined in JavaScript (the current element completes; not-yet-visited deleted elements are skipped), so the other listeners are unaffected. Verified: eslint problem count unchanged, Metro release bundle builds. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The top-level call to CleverTapReact.getDefaultAccountId() runs when the module is imported. If the linked native module has no such method - a native binary older than this JS (stale pods, no Android rebuild) or a partial Jest mock in a customer's test suite - the property call threw a TypeError inside module evaluation and the WHOLE SDK import failed. The existing .catch could not help: the throw happened before any promise existed. Before this PR the import only needed getConstants and setLibrary from the native module; this call had quietly added a third requirement. The call is now made only when the method exists; otherwise a rejected promise flows into the existing .catch, which already logs the warning and falls back to currentDefaultAccountId. Behavior and timing when the method exists are unchanged (the call only enqueues a native request and returns a promise; nothing waits on it). Verified: eslint problem count unchanged, Metro release bundle builds. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Every optional field of createInstance(config) was read straight off the
bridge map where it was used, and on both platforms that read crashes the
app for inputs a JS caller can easily send:
- Android: ReadableMap.getBoolean on a JS null unboxes a null
(NullPointerException); on a string it throws
UnexpectedNativeTypeException. Those reads ran inside the main-thread
creation task, outside the promise's reach - the process died.
- iOS: [NSNull boolValue] is an unrecognized selector, and a number under
a string key went to the SDK as an NSString.
A server-provided config such as {"analyticsOnly": null} is a normal input,
so the fix is one parsing step, identical on both platforms, run BEFORE any
native object is built:
- a missing key or a JS null means "not set";
- a value of the wrong type rejects the promise with EINVALID naming the
field ("analyticsOnly must be a boolean", "android.pushProviders[0].type
is required").
Android: new InstanceConfigRequest (Kotlin, pure data, no Context/SDK) with
typed readers; createInstance now parses on the calling thread, builds the
CleverTapInstanceConfig from the validated object (plain data, no main
thread needed), and hops to the main thread only for instanceWithConfig.
applyAndroidOnlyConfig is folded into applyOptionalConfig. Nine JVM tests
cover null values, wrong types, credentials, the cleverTapId pairing,
identityKeys elements and push-provider validation.
iOS: new CleverTapReactInstanceConfigRequest (Objective-C twin of the Kotlin
class: same fields, same rules, same messages) with sticky-error typed
readers; createInstance: is the same three steps. The ad-hoc type checks
added for the cleverTapId pairing are replaced by the parser.
Behavior changes besides "no crash": a push provider missing one of its
four required parts now rejects EINVALID (it was skipped with a warning);
proxyDomain: null no longer calls setProxyDomain(null) on Android.
Verified: JVM tests 16/16 (7 emitter, 9 parser), Android module compiles
on both architectures, iOS pod install + Example app build, tsc on the
typings.

200-204: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy liftKeep untagged events buffered for top-level listeners.
A per-account
armAndFlushcurrently activates and drains untagged events. However,src/index.jsroutes untagged events only to the default slot.If only an account handle listens, Android sends these events and JavaScript drops them. A later top-level listener cannot recover them.
Pass enough listener-scope information to distinguish the default slot from an account handle. Only drain and activate untagged events for the default slot. Update
armAndFlush_deliversOwnAccountAndUntagged_keepsOtherAccountsto match this contract.Also applies to: 234-234

- Around line 103-107: Update the parsing flow in InstanceConfigRequest around
logLevel and encryptionLevel to validate non-null values against the exact
lowercase domains: logLevel must be off, info, debug, or verbose;
encryptionLevel must be none, medium, or high. Preserve null as unset, and
reject invalid values with errors that identify the corresponding field instead
of allowing unknown strings through.
In `@ios/CleverTapReact/CleverTapReactInstanceConfigRequest.m`:
- Around line 31-34: Update ctReadBool to accept only NSNumber instances whose
Core Foundation type is CFBooleanGetTypeID(), rejecting numeric NSNumber values
so they produce EINVALID while preserving valid JavaScript booleans.

…stance config Two gaps in the config parsers added in 654c458, found by review: - logLevel / encryptionLevel accepted any string and an unknown word fell back silently to a default SDK level: `encryptionLevel: "HIGH"` meant "none" without a word to the developer. Both parsers now accept exactly off/info/debug/verbose and none/medium/high (null stays "not set"); anything else rejects EINVALID naming the field and the allowed values. - On iOS a JS number passed the boolean readers because numbers and booleans are both NSNumber, so `analyticsOnly: 1` was accepted (and 2 would read as YES) while Android's ReadableType.Boolean check rejected it. ctReadBool now also requires CFBooleanGetTypeID(), so both platforms reject the same inputs. The __bridge cast borrows the pointer without changing its retain count. Verified: JVM tests 17/17 (new parse_logLevelAndEncryptionLevel_ acceptOnlyKnownValues), Android module compiles on both architectures, Example iOS app builds.

Jira: SDK-6047
Adds full multi-instance (multi-account) support to the React Native SDK: an app can create and use additional CleverTap accounts from JavaScript, with per-account events, listeners, variables, custom templates, and push-permission flows.
What an app can do now
initReactNativeIntegration(context, launchConfigs)(Android) /applicationDidLaunchWithOptions:launchConfigs:(iOS), then used from JS withgetInstance(accountId)— including an optional per-account custom CleverTap ID.Bugs fixed along the way
NoSuchElementExceptionon the old code is included as a JVM unit test.setLocationmisroute; iOS pending-events statics race (main-queue confinement); JS demux crash on string payloads.createInstancenow applies the passed config on every fresh launch (matches native semantics); previously a stale persisted config could be resurrected.createNotification, and the push-permission trio work in apps with no manifest/plist account; iOSisPushPermissionGrantedcompletes its callback with an error instead of hanging when no instance exists.Compatibility
NativeModules.CleverTapReactcallers on the OLD architecture are affected: ~120 native method signatures gained a trailingaccountIdargument. Apps using the documentedCleverTapJS module are unaffected.initReactNativeIntegrationkeeps its one-argument form (@JvmOverloads); the iOS manager keeps the existingapplicationDidLaunchWithOptions:.Testing
