API timeout issues occur when a request does not receive a response within the expected time. They can be caused by network conditions, request volume, integration configuration, service availability, or the complexity of the request being processed.
Common symptoms
- the request fails after a waiting period;
- the integration reports a timeout error;
- timeouts occur only from one environment or network;
- timeouts happen intermittently;
- large batches or repeated requests are affected more often than single requests.
What to check first
- Confirm the endpoint and environment used by the request.
- Check whether the timeout occurs consistently or only at specific times.
- Test the same request from another environment or network if possible.
- Review recent infrastructure, proxy, firewall, or network changes.
- Check whether the request volume or retry behavior changed recently.
Integration best practices
- Set reasonable timeout values in your application.
- Avoid aggressive retry loops that can increase traffic during incidents.
- Log request timestamps, endpoints, status codes, and response times.
- Separate transient network errors from repeated service failures.
When to contact DQE Support
If timeouts are frequent or affect production, create a support ticket with the endpoint, environment, request timestamp, frequency of the issue, sample request, response or error message, and any recent network or deployment changes.
