Trace the data from source to destination, then assign an owner for the handoff rather than only the individual tools. Ownership needs to include failures, retries, and reconciliation.

Map the contract between systems

Document the trigger, required fields, field mapping, and expected delivery time. Record what should happen when a destination is unavailable or a record arrives twice.

Make recovery part of delivery

An integration is not complete when the happy path works. Give the operating team a way to identify failed records, replay safely, and reconcile outcomes without creating duplicates.
