How do I find my AppsFlyer API Token V2?

Log in to AppsFlyer as an Admin, go to **Security Center** from the account menu, and navigate to **AppsFlyer API tokens**. There you can manage and copy your V2 token (JWT).

The `appId` is the unique identifier for your app in the store. For iOS, it's usually `id` followed by numbers (e.g., `id123456789`). For Android, it's the package name (e.g., `com.example.app`).

Is there a limit on the number of rows returned?

Yes, AppsFlyer Pull API limits raw data reports to 200,000 rows. If your data exceeds this, try narrowing the date range of your request.
