With environments aligned, the last conceptual piece is what happens to one session over time. That shapes how you fulfil orders—before you memorize individual SDK calls in the next section.

​
Session states

Server types mirror the REST API. Common status values include:
  • pending — created, not yet confirmed on-chain
  • confirmed — settled and verified
  • expired — session TTL elapsed
  • cancelled — cancelled via API (only pending sessions)
Use unseen.payments.get(id) or list filters to observe state from the server.

​
Verification

payments.verify(paymentId) (server SDK) or the UI’s polling flow returns a result whose status can include:
  • confirmed
  • pending
  • amount_mismatch — amount on-chain does not match the session (treat as failure / manual review)
The UI polls for a limited window after the user taps I have paid; if confirmation is slow, retry verify from the server or rely on webhooks.

​
Fulfillment checklist

  1. Treat idempotency: the same payment ID or reference may be observed more than once (retries, webhook + client).
  2. Prefer webhooks + verify together: webhook for push, verify for manual recovery.
  3. Store reference as your internal order or invoice key.
Next: Server SDK — Installation — turn these states into typed API calls.
