​
Common SDK flow

1

Generate token (server-side)

Call the token generation 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.
