Get Install ID

SDK Version Selection

Choose your SDK version below:

  • Apptrove SDK → AppTroveFlutterSdk.getAppTroveId() (Recommended)
  • Trackier SDK → Trackierfluttersdk.getTrackierId() (Deprecating August 2026)

Use the tabs below for your chosen SDK.

The install ID is a unique UUID the SDK creates on first launch and stores on the device. It identifies this app install (not your login user ID). Use it for S2S events (tr_id), uninstall tracking, support/QA matching, and joining first-party data.

SDKMethod
ApptroveAppTroveFlutterSdk.getAppTroveId()
TrackierTrackierfluttersdk.getTrackierId()
note

Call this after SDK initialization. An empty value usually means the SDK has not created the ID yet.

Usage​

final installId = await AppTroveFlutterSdk.getAppTroveId();
print('Install ID: $installId');

Uninstall tracking (Firebase)​

final installId = await AppTroveFlutterSdk.getAppTroveId();
await FirebaseAnalytics.instance.setUserProperty(
  name: 'ct_objectId',
  value: installId,
);

Also see Uninstall Tracking.

Use cases​

1. Server-to-Server (S2S) events​

Pass the install ID as tr_id on S2S Events:

{
  "app_token": "abcf2270-XXXX-XXXX-XXXX-34903c6e1d53",
  "tr_id": "5da45091-XXXX-XXXX-XXXX-b2a1587e0d8b",
  "event_id": "sEMWSCTXeu"
}

Flow: initialize SDK → read install ID → send to backend → backend uses it as tr_id.

2. Uninstall tracking​

Set Firebase ct_objectId to the install ID (examples above).

3. Support and QA​

Log the install ID, then search Logs → Install Logs in the panel by that ID.

4. Join with your user ID​

Your systemSDK
Login / account IDsetUserId
Install ID (tr_id)AppTroveFlutterSdk.getAppTroveId() / Trackierfluttersdk.getTrackierId()

Do not use the install ID alone as a lifelong account key.

Find it in the panel​

  1. Open Logs → Install Logs
  2. Open an install
  3. Copy the ID

Best practices​

  • Initialize the SDK before reading the ID
  • Sync the ID to your backend when you need S2S
  • Expect a new ID after app reinstall

Troubleshooting​

IssueCheck
Empty IDSDK not initialized, or called too early
S2S not matchingConfirm tr_id equals the SDK install ID
