- 01Alevo creates a payment request
- 02Customer opens the hosted checkout
- 03Gateway processes the selected method
- 04Webhook is verified and made idempotent
- 05Alevo allocates the payment to the invoice
The gateway is the payment authority
Alevo should record and reconcile gateway outcomes; it should not treat a browser redirect alone as proof of settlement.
Integration boundary
payment request → provider checkout → signed webhook → idempotent allocation → invoice timeline
