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.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
Serialize the arm, drain, and same-account send paths
CleverTapModuleImpl.onEventListenerAdded calls armAccount and flushBuffer separately. After Buffer.arm releases its monitor, emit can send a same-account event immediately before flushBuffer drains older buffered events. Combining arm and drainFor is not sufficient if the drained list is sent after the monitor is released; a newer event can still reach sendEvent first. Serialize the drained events and subsequent same-account emits through one dispatch path while keeping React Native calls outside the monitor.

CleverTap iOS SDK enablePersonalization instance method CleverTapInstanceConfig enablePersonalization
💡 Result:
In the CleverTap iOS SDK, personalization is managed through two primary mechanisms: a static method for the default CleverTap instance and a configuration property for additional (multi-instance) CleverTap configurations [1][2]. Default CleverTap Instance To enable the Profile/Events Read and Synchronization API for the default shared instance, you call the class method enablePersonalization [3][1][4]. This should typically be done once at application launch, such as in your AppDelegate [1]: Objective-C: [CleverTap enablePersonalization]; Swift: CleverTap.enablePersonalization Additional CleverTap Instances When using CleverTapInstanceConfig to manage additional CleverTap instances, personalization is controlled via the enablePersonalization property on the configuration object before the instance is initialized [2]. Objective-C: CleverTapInstanceConfig *ctConfig = [[CleverTapInstanceConfig alloc] initWithAccountId:@"YOUR_ACCOUNT_ID" accountToken:@"YOUR_ACCOUNT_TOKEN"]; ctConfig.enablePersonalization = NO; // Or YES to enable, which is the default CleverTap *additionalInstance = [CleverTap instanceWithConfig:ctConfig]; Swift: let ctConfig = CleverTapInstanceConfig.init(accountId: "YOUR_ACCOUNT_ID", accountToken: "YOUR_ACCOUNT_TOKEN") ctConfig.enablePersonalization = false // Or true to enable, which is the default let additionalInstance = CleverTap.instance(with: ctConfig) Important Note: Be sure to call enablePersonalization prior to using methods that rely on it, such as profile synchronization or retrieving user profile properties [3][5][4].

Resolve the instance before dispatching to the global queue. methodQueue returns the main queue, but getUserEventLog, getUserEventLogCount, getUserEventLogHistory, and getUserAppLaunchCount call resolveInstance: inside global queue blocks. resolveInstance: mutates defaultInstance and wiredAccountIds, then calls setDelegates:, which reads and writes handlers. These collections can race with main-queue bridge methods. Resolve the instance before each dispatch_async block and capture it for the background operation at lines 483, 494, 504, and 652.

Add nil handling to all three fetch methods.
For an unknown accountId, resolveInstance: returns nil. Objective-C messaging then skips fetchInApps:, fetchInboxWithCallback:, and fetchVariables:. Their callbacks do not run. callWithCallback supplies a callback, so callers that wrap these methods in a Promise can remain pending.
Add the explicit nil check before the SDK call in fetchInApps:, fetchInbox:, and fetchVariables:. Return "CleverTap is not initialized" through returnResult:withCallback:andError:. Keep fetchInbox:'s callback == NULL branch after the nil check.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Guard the import-time getDefaultAccountId() call.
This call runs when the module is imported. If CleverTapReact.getDefaultAccountId is undefined, the property call throws a TypeError during import and the whole SDK import fails, not only event routing. That state occurs when a newer JavaScript package runs against an older native binary, and in test environments where the native module is partially mocked. The existing .catch does not help, because the throw happens before a promise exists.
🛡️ Proposed fix to fall back when the native method is missing
-const defaultAccountIdReady = CleverTapReact.getDefaultAccountId().then((id) => {
+const defaultAccountIdPromise = typeof CleverTapReact.getDefaultAccountId === 'function'
+ ? CleverTapReact.getDefaultAccountId()

Remove one-time subscriptions before invoking handlers. deliverRouted catches handler exceptions. If handler(event) throws, the later subscription.remove() call is skipped, so the wrapper remains registered and can run again.

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>

I can see [self resolveInstance:accountId] method can return nil, so calling native ios methods on nil may leads to crash, we have to write guard nil check everywhere this is used. please verify this and make changes if needed at this place and other places also

why accountId is not optional here and at some places below?

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
