Creative External API
The Creative External API uploads creative assets and publishes ads to ad networks programmatically, bypassing the AppsFlyer Creative Dashboard UI. It is asynchronous — a batch is submitted for upload and publication and returns a batch identifier, then per-item processing status and results are polled separately (AppsFlyer recommends starting at a 5-second poll interval with exponential backoff capped at 60 seconds). Facebook (Meta) is the currently supported destination network. Authenticated with the account API V2 token as a bearer token.
