Design reliable integrations from day one
A practical approach to retries, observability, and keeping customer data in sync.
Expect partial failure
External services will time out, deliver duplicate events, and change their limits. Treat those conditions as normal design inputs. Use idempotent operations so processing the same event twice does not create duplicate customer records.
Make recovery observable
Use bounded retries with backoff, and send repeated failures to a queue your team can inspect. Keep enough context to trace an event across systems without logging sensitive payloads. Document who owns alerts and how to replay failed work safely.
Before release, test expired credentials, rate limits, and out-of-order events. Give customers a clear connection status and a way to reconnect. Reliable integrations need understandable recovery paths as much as a successful first sync.
