Define transferred data, source ownership, error handling and retry behaviour before connecting two business systems.
A successful connection does not establish a successful integration. Duplicate orders or silently stale stock can occur while systems remain connected. Plan beyond the happy path.
Assign source ownership
Decide which system owns product names, prices and stock. Define conflict rules when both sides can edit a field, plus transfer direction and timing.
Map sample records
Codes, currencies, dates and status values may differ. Validate mappings with anonymised records and define handling for empty or unsupported values.
Design failures and retries
Specify which operations may be retried and how repeated messages avoid duplicate orders. Make failed records visible to authorised staff without logging secret keys.
Launch in a controlled way
Validate a small dataset first. Assign permissions, monitoring, rollback and ownership. Check the chosen service's current documentation and limits instead of copying assumptions from a different integration.
