HTTP Status Codes Browse HTTP status code reference HTTP Status Code Lookup Browse HTTP status codes with description and troubleshooting Informational These codes indicate that the server has received the request headers and the client should continue to send the body, or that the server is switching to a different protocol. These are provisional responses with no actual body content. Success These codes indicate that the client's request was successfully received, understood, and accepted. This is the category every developer hopes to see — everything worked as expected. HTTP 200 POPULAR OK. The request has succeeded. The meaning of the success depends on the HTTP method used. Redirection These codes indicate that the client must take additional action to complete the request. Usually this means the resource has moved and the client needs to follow the redirect to a new URL. HTTP 301 Moved Permanently. The target resource has been assigned a new permanent URI and any future references should use the new URI. HTTP 302 Found. The target resource resides temporarily under a different URI. HTTP 304 Not Modified. A conditional GET request has been received and would have resulted in a 200 response if the condition was false. Client Error These codes indicate that the request contains bad syntax or cannot be fulfilled by the server. The error is typically on the client side — malformed syntax, unauthorized access, or requesting a resource that doesn't exist. HTTP 400 POPULAR Bad Request. The server cannot or will not process the request due to something perceived as a client error. HTTP 401 Unauthorized. The request has not been applied because it lacks valid authentication credentials for the target resource. HTTP 403 POPULAR #1 Forbidden. The server understood the request but refuses to authorize it. HTTP 404 Not Found. The origin server did not find a current representation for the target resource or is not willing to disclose that one exists. HTTP 405 Method Not Allowed. The method received in the request-line is known by the origin server but not supported by the target resource. HTTP 408 Request Timeout. The server did not receive a complete request message within the time it was prepared to wait. HTTP 410 Gone. The target resource is no longer available at the origin server and this condition is likely permanent. HTTP 418 I'm a Teapot. This code was defined in 1998 as an April Fools' joke in RFC 2324, Hyper Text Coffee Pot Control Protocol. HTTP 429 POPULAR Too Many Requests. The user has sent too many requests in a given amount of time (rate limiting). Server Error These codes indicate that the server failed to fulfill a valid request. The error is on the server side — the server encountered an unexpected condition that prevented it from fulfilling the request. HTTP 500 Internal Server Error. The server encountered an unexpected condition that prevented it from fulfilling the request. HTTP 502 Bad Gateway. The server, while acting as a gateway or proxy, received an invalid response from an inbound server. HTTP 503 POPULAR Service Unavailable. The server is currently unable to handle the request due to a temporary overload or scheduled maintenance. HTTP 504 Gateway Timeout. The server, while acting as a gateway or proxy, did not receive a timely response from an upstream server.
