Network timeouts can cause a client to retry an HTTP request or a message broker to redeliver an event. If the original request succeeded but the acknowledgment failed, the service will process the duplicate request. Ensure your operations are idempotent by tagging requests with a unique X-Idempotency-Key and validating it against a Redis cache before executing mutations. 6.
