A Checklist for Reliable API Integrations
A successful integration treats failure, duplication, and rate limits as seriously as the happy path.

The decision that should precede delivery
Design requests to be idempotent wherever possible. Add timeouts, backoff retries, traceable logs, and keep provider secrets outside source control.
Document system boundaries, failure modes, and data ownership before choosing technical details. A sound engineering decision explains the cost of operation and change, not only initial build cost.
A reviewable checklist
- Verify signatures
- Use idempotency keys
- Monitor latency and errors
- Test provider outages
Review questions before scaling
- Has the team documented: Verify signatures?
- Has the team documented: Use idempotency keys?
- Has the team documented: Monitor latency and errors?
Keep each answer beside the decision, owner, and review date. If the required signal is unavailable, reduce the experiment instead of expanding delivery scope.
Turn the insight into an action
Choose one decision you can apply this week, assign an owner and success signal, then review the result before expanding scope.
