Obtain Authorization Code

Invoke authorization request in order to initiate face authentication flow with UAE PASS from the SP application.

The user shall be presented with UAE PASS confirmation screen on the UAE PASS app followed by face verification to confirm the request.

On success/failure the control will return back to the SP portal callback URL with appropriate status. In case of success the SP web portal will receive the “authorization code” to the callback URL of SP (which is pre-configured in UAE PASS). (Just change the "redirect_uri" and "client_id" appropriately as per your environment and other parameters as applicable).
