HTTP 201 Created vs 504 Gateway Timeout
HTTP 201 (Created) is a 2xx Success response, while 504 (Gateway Timeout) is a 5xx Server Error response. 201 indicates that the request succeeded and a new resource was created. Typically returned after POST or PUT requests that create a new entity. In contrast, 504 means that the server, acting as a gateway or proxy, did not receive a timely response from the upstream server.
