About this demo

This site stores no orders. The PsiFi session is the source of truth. When the customer returns from the hosted page, this server hits GET /api/v2/checkout-sessions/:id to confirm payment status, and the webhook handler logs the signed event without touching any database.

For a production integration with order persistence, fulfillment, confirmation emails, and side-effect orchestration, see the full installation skill at docs/psifi-checkout-skill.md in the companion repo.
