Build your integration in the free sandbox before preparing for production.
Build the first identity onboarding result handler before collecting any document. This walkthrough uses an account-free synthetic response; it does not create a hosted provider session. Your application must keep verification decisions separate from seller permissions.
Add a pre-registration number check while keeping invalid numbers separate from unavailable results. A format or validity signal cannot prove ownership or SMS reachability. This walkthrough returns no line type and sends no OTP.
Recover a delayed callback without creating duplicate sessions. The runnable local example stores state in SQLite, enforces a deadline and rejects late permission grants. Its callback channel is explicitly synthetic: it is not a live signature verifier.
Turn a verification result into a bounded application decision. Test account binding, explicit policy, duplicate events and rejection handling in a local fixture database. The permission shown in this walkthrough is a demo flag, not a real seller permission.
