A Checklist for Reliable API Integrations

A successful integration treats failure, duplication, and rate limits as seriously as the happy path.

A practical framework

Design requests to be idempotent wherever possible. Add timeouts, backoff retries, traceable logs, and keep provider secrets outside source control.

Checklist

• Verify signatures
• Use idempotency keys
• Monitor latency and errors
• Test provider outages

The next step

Choose one decision you can apply this week, assign an owner and success signal, then review the result before expanding scope.
