How to Handle API Rate Limits Without Losing Business Events

An API rate limit can interrupt integrations during peak activity. If the system drops events instead of queueing or retrying them, records may never reach the provider even after the limit window resets.

What to check

Review rate-limit headers, retry-after guidance, queue depth, event retention, concurrency, and dead-letter handling. Identify whether retries are bounded and whether duplicate delivery is safe.

Recommended next step

Queue work durably, honor provider retry guidance, and use backoff with idempotency. Alert on growing backlog and reconcile missed events after recovery rather than assuming the provider will replay them.
