initiateIDVBiometricOptIn

🔍 Overview

The initiateIDVBiometricOptIn API is used to opt-in a logged-in user for biometric authentication by capturing and uploading their selfie to the REL-ID server. This is a post-login flow and depends on the user’s current authentication session.

🖥️ Recommended Screen

The app should:

• Display a loading or biometric setup screen before the selfie capture.
• Guide the user through any OS-native authentication (biometric/pattern/password).
• Present a selfie preview and confirmation prompt post-capture.

🔁 API to Trigger Biometric Opt-In

✳️ initiateIDVBiometricOptIn

🔁 Workflow and Follow-up Events

1. SDK prompts user for authentication:
   1. OS biometric (Face ID / fingerprint / PIN)
   2. or invokes getPassword callback if user logged in with password
2. SDK Triggers getIDVSelfieProcessStartConfirmation and user consent is submitted with setIDVSelfieProcessStartConfirmation
