HTTP Status Codes

A complete list of HTTP status codes, from success messages to client and server errors.

CodeNameDescription
100ContinueThe client should continue with its request.
101Switching ProtocolsThe server is switching protocols according to the Upgrade header.
102ProcessingThe server has received and is processing the request, but no response is available yet.
103Early HintsUsed to return some response headers before final HTTP message.
200OKThe request succeeded.
201CreatedThe request succeeded, and a new resource was created as a result.
202AcceptedThe request has been accepted for processing, but the processing has not been completed.
203Non-Authoritative InformationThe returned meta-information is not the definitive set as available from the origin server, but is gathered from a local or a third-party copy.
204No ContentThe server successfully processed the request and is not returning any content.
205Reset ContentThe server successfully processed the request, but is not returning any content. Unlike a 204 response, this response requires that the requester reset the document view.
206Partial ContentThe server is delivering only part of the resource due to a range header sent by the client.
207Multi-StatusProvides status for multiple independent operations.
208Already ReportedUsed inside a DAV: propstat response element to avoid enumerating the internal members of multiple bindings to the same collection repeatedly.
226IM UsedThe server has fulfilled a GET request for the resource, and the response is a representation of the result of one or more instance-manipulations applied to the current instance.
300Multiple ChoicesIndicates multiple options for the resource from which the client may choose.
301Moved PermanentlyThis and all future requests should be directed to the given URI.
302FoundTells the client to look at (browse to) another URL.
303See OtherThe response to the request can be found under another URI using a GET method.
304Not ModifiedIndicates that the resource has not been modified since the version specified by the request headers If-Modified-Since or If-None-Match.
305Use ProxyThe requested resource is available only through a proxy, the address for which is provided in the response.
306Switch ProxyNo longer used. Originally meant 'Subsequent requests should use the specified proxy.'
307Temporary RedirectIn this case, the request should be repeated with another URI; however, future requests should still use the original URI.
308Permanent RedirectThe request and all future requests should be repeated using another URI.
400Bad RequestThe server cannot or will not process the request due to an apparent client error.
401UnauthorizedSimilar to 403 Forbidden, but specifically for use when authentication is required and has failed or has not yet been provided.
402Payment RequiredReserved for future use. The original intention was that this code might be used as part of some form of digital cash or micropayment scheme, but that has not happened.
403ForbiddenThe request was valid, but the server is refusing action. The user might not have the necessary permissions for a resource, or may need an account of some sort.
404Not FoundThe requested resource could not be found but may be available in the future. Subsequent requests by the client are permissible.
405Method Not AllowedA request method is not supported for the requested resource.
406Not AcceptableThe requested resource is capable of generating only content not acceptable according to the Accept headers sent in the request.
407Proxy Authentication RequiredThe client must first authenticate itself with the proxy.
408Request TimeoutThe server timed out waiting for the request.
409ConflictIndicates that the request could not be processed because of conflict in the request, such as an edit conflict.
410GoneIndicates that the resource requested is no longer available and will not be available again.
411Length RequiredThe request did not specify the length of its content, which is required by the requested resource.
412Precondition FailedThe server does not meet one of the preconditions that the requester put on the request.
413Payload Too LargeThe request is larger than the server is willing or able to process.
414URI Too LongThe URI provided was too long for the server to process.
415Unsupported Media TypeThe request entity has a media type which the server or resource does not support.
416Range Not SatisfiableThe client has asked for a portion of the file, but the server cannot supply that portion.
417Expectation FailedThe server cannot meet the requirements of the Expect request-header field.
418I'm a teapotAny attempt to brew coffee with a teapot should result in the error code '418 I'm a teapot'. The resulting entity body MAY be short and stout.
421Misdirected RequestThe request was directed at a server that is not able to produce a response.
422Unprocessable EntityThe request was well-formed but was unable to be followed due to semantic errors.
423LockedThe resource that is being accessed is locked.
424Failed DependencyThe request failed due to failure of a previous request.
425Too EarlyIndicates that the server is unwilling to risk processing a request that might be replayed.
426Upgrade RequiredThe client should switch to a different protocol such as TLS/1.0, given in the Upgrade header field.
428Precondition RequiredThe origin server requires the request to be conditional.
429Too Many RequestsThe user has sent too many requests in a given amount of time.
431Request Header Fields Too LargeThe server is unwilling to process the request because either an individual header field, or all the header fields collectively, are too large.
451Unavailable For Legal ReasonsA server operator has received a legal demand to deny access to a resource or to a set of resources that includes the requested resource.
500Internal Server ErrorA generic error message, given when an unexpected condition was encountered and no more specific message is suitable.
501Not ImplementedThe server either does not recognize the request method, or it lacks the ability to fulfill the request.
502Bad GatewayThe server was acting as a gateway or proxy and received an invalid response from the upstream server.
503Service UnavailableThe server is currently unavailable (because it is overloaded or down for maintenance). Generally, this is a temporary state.
504Gateway TimeoutThe server was acting as a gateway or proxy and did not receive a timely response from the upstream server.
505HTTP Version Not SupportedThe server does not support the HTTP protocol version used in the request.
506Variant Also NegotiatesTransparent content negotiation for the request results in a circular reference.
507Insufficient StorageThe server is unable to store the representation needed to complete the request.
508Loop DetectedThe server detected an infinite loop while processing the request (sent instead of 208 Already Reported).
510Not ExtendedFurther extensions to the request are required for the server to fulfill it.
511Network Authentication RequiredThe client needs to authenticate to gain network access.
