        - For an embedded session, provide `verification`. The response returns a `link` to launch or embed the frontend experience. The `link` expires after one hour.


        - For an invite, first create the user and at least one active verification. Set `type` to `invite`, provide `user`, and include `configuration.email`, `configuration.phone_number`, or both. The invite link expires after 180 days or when revoked.

You can include an application-owned state or nonce value to match the returning browser session to an internal user, session, or verification. Argyle appends `user_submission_complete` and `user_attempted_employer_selection`, which mirror the [`onClose`](/link/reference/callbacks#onclose) fields.

For banking, pass this value to the [banking SDK](/verifications/verification-types/banking#launch-the-banking-session) as `connectURL`.
