Integrations and source ownership

• Commerce channel. Agree how channel orders map to customer orders and their lines; retain the sales channel and order number on the order.
• Payment provider. Bring capture, failure and refund evidence into the order’s payment record with its provider reference and USD amount.
• Carrier. Retain the handoff channel, carrier reference and observed delivery events on the linked order.

Agree which system owns each source fact, how it identifies an event and who investigates rejected input. Repeated provider or carrier messages should be compared with existing evidence before adding another record. Map customer, product and order identities before processing later events. For any connection you set up, limit access by role and organization and rehearse duplicate, late and corrected records with the people who resolve them.

Use the implementation plan.
