# Response status codes (/en/api-reference/api-ref/rtmp-gateway/response-status-codes)

> For AI agents: see the complete documentation index at [llms.txt](/llms.txt).

After sending an HTTP request, the server returns a status code. Use the status code to determine whether the request succeeded and why a request might have failed.

* If the status code is `2XX`, the request was successful.
* If the status code is not `2XX`, the request failed. Troubleshoot the problem based on the `message` field in the response body.
