Create a short-lived verification session and redirect your user to the returned H5 link. TokenLab returns only neutral fields: session_id, verification_token, h5_link, callback_url, expires_in, and language. The session, token, and H5 link expire after 120 seconds. When the H5 flow completes, TokenLab redirects to your original callback_url with these query parameters:
ParameterMeaning
session_idTokenLab verification session ID.
verification_tokenOpaque token used to bind the result.
verification_statussucceeded or failed.
result_codeResult code for your application logic.
If verification_status is succeeded, call Bind Real-Person Verification Result. The test console can be used to verify callback handling before you wire the flow into your product.
