Common SDK Flow

1. Create session (server-side)

   Call the session creation API from your backend.

2. Pass token to SDK

   Send the authToken to your mobile app.

3. Initialize SDK

   Start the verification flow with the token.

4. Handle callback

   Receive the local SDK callback AND the server webhook for the final result.

Always use the server-side webhook as the source of truth for verification results, not the SDK callback. The SDK callback only indicates that the user completed the flow — the final result comes via webhook after processing.
