If you want to further clarify the error you can either change the Reason Phrase or include a body to explain the error. 412 - Precondition failed is used for conditional requests when using last-modified date and ETags. 403 - Forbidden is used when the server wishes to prevent access to a resource. The only other choice that is possible is 422 - Unprocessable entity. share|improve this answer answered May 25 '11 at 11:32 Darrel Miller 86k17131196 7 while it is often used in this context, 403 is not limited to acces control, since rfc2616-10.4.4 says: "The server understood the request, but is refusing to fulfill it. [...] if the server wishes to make public why the request has not been fulfilled, it SHOULD describe the reason for the refusal in t
Codes For Invalid Data: 400 vs. 422 By Ben Nadel on October 17, 2012 Tags: ColdFusion Let's say that someone makes a request to your server with data that is in the correct format, but is simply not "good" data. http status code 422 So for example, imagine that someone posted a String value to an API endpoint that

expected a String value; but, the value of the string contained data that was blacklisted (ex. preventing people from using "password" as their password). http status code for validation error What HTTP status code would you return?Until now, I would have returned a "400 Bad Request", which, according to the w3.org, means:The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat http://stackoverflow.com/questions/6123425/rest-response-code-for-invalid-data the request without modifications.This description doesn't quite fit the circumstance; but, if you go by the list of core HTTP status codes defined in the HTTP/1.1 protocol, it's probably your best bet.Recently, however, Jamie Krug pointed out [to me] that popular APIs are starting to use HTTP extensions to get more granular with their error reporting. Specifically, many APIs, like Twitter and Recurly, are using the status code "422 Unprocessable Entity" as defined in the HTTP extension for WebDAV. https://www.bennadel.com/blog/2434-http-status-codes-for-invalid-data-400-vs-422.htm HTTP status code 422 states:The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415 (Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.Going back to our password example from above, this 422 status code feels much more appropriate. The server understands what you're trying to do; and it understands the data that you're submitting; it simply won't let that data be processed.HTTP status code 422 feels like a much more appropriate response for situations where the data is understood, but is still not valid. I think I'll start using this going forward. Thanks Jamie!
