What's an appropriate HTTP status code to return by a REST API service for a validation failure?
- by michaeljoseph
I'm currently returning 401 Unauthorized whenever I encounter a validation failure in my Django/Piston based REST API application.
Having had a look at the HTTP Status Code Registry
I'm not convinced that this is an appropriate code for a validation failure, what do y'all recommend?
400 Bad Request
401 Unauthorized
403 Forbidden
405 Method Not Allowed
406 Not Acceptable
412 Precondition Failed
417 Expectation Failed
422 Unprocessable Entity
424 Failed Dependency
Update: "Validation failure" above means an application level data validation failure ie. incorrectly specified datetime, bogus email address etc.
