If for example the user asked for “account” and that account was not found there are 2 options to use for returning an error to the user: Return 200 OK Status However, this specification does not define any standard for such automatic selection. In common use, a response carrying the 511 status code will not come from the origin server indicated in the request's URL. No indication is given of whether the condition is temporary or permanent.

Bottom line, it's about making your APIs intuitive and making developers successful. Wikipedia The requested resource is only capable of generating content not acceptable according to the Accept headers sent in the request. 407 Proxy Authentication Required This code is similar to 401 If the response is the result of an If-Range request that used a weak validator, the response MUST NOT include other entity-headers; this prevents inconsistencies between cached entity-bodies and updated headers. If the server does not wish to make this information available to the client, the status code 404 (Not Found) can be used instead.

Twilio Twilio does a great job aligning errors with HTTP status codes. It's a REST API, so meaningful HTTP status codes are a must.

Subsequent requests by the client are permissible. I've implemented similar solution.

It's not nearly as simple as your first best practice item suggests. Wikipedia The request did not specify the length of its content, which is required by the requested resource. 412 Precondition Failed The precondition given in one or more of the request-header It's looks cool in code: return new ErrorResponse(ErrorResponse::SOME_ENTITY_NOT_FOUND ); Easy to change error message.

The set presented MAY be a subset or superset of the original version. However, most existing user agent implementations treat 302 as if it were a 303 response, performing a GET on the Location field-value regardless of the original request method. For instance, a POST request must be repeated using another POST request. 308 Permanent Redirect (experiemental) Wikipedia The request, and all future requests should be repeated using another URI. 307 and Or, perhaps, it is hard to come up with one best practice, and it makes more sense to develop error handling on a case-by-case basis?

The proxy MUST return a Proxy-Authenticate header field (section 14.33) containing a challenge applicable to the proxy for the requested resource. Hence, XooMLe returns back the following XML document: doGoogleSearch Invalid Google API key supplied en ISO-8859-1 oreilly php The Amazon.com web services API It may have provided the wrong credentials or none at all. 403 (Forbidden) should be used to forbid access regardless of authorization state A 403 error response indicates that the client’s If you would ask me 5 years ago about HTTP Status codes I would guess that the talk is about web sites, status 404 meaning that some page was not found

Its purpose is to allow a server to accept a request for some other process (perhaps a batch-oriented process that is only run once per day) without requiring that the user Wikipedia Indicates multiple options for the resource that the client may follow. When received in response to a POST (or PUT/DELETE), it should be assumed that the server has received the data and the redirect should be issued with a separate GET message. So, let’s talk a bit about some of the best practices that we believe make for a good developer and client experience.

Sending an error response in a HTTP 200 envelope is misleading, and forces the client (api consumer) to parse the message, most likely in a non-standard, or proprietary way. A 500 error is never the client’s fault and therefore it is reasonable for the client to retry the exact same request that triggered this response, and hope to get a The information returned with the response is dependent on the method used in the request, for example: GET an entity corresponding to the requested resource is sent in the response; HEAD How could a language that uses a single word extremely often sustain itself?
