Standard error codes

Defra uses standard HTTP status codes to show whether an API request succeeded or not. They are usually in the range:

Code	Official description	Explanation in context of the API
200	OK
304	Not modified	In response to a conditional GET request, this response indicates that the underlying data has not changed since the previous request, and cached results may be re-used.
400	Bad request	For example missing query parameter or malformed syntax
401	Unauthorized	The client has not provided authentication or incorrect authentication
404	Not found	The server has not found anything matching the request-URI
405	Method not allowed	Request used an unsupported HTTP method. For example DELETE or PUT
500	Internal server error	Generic internal server error
503	Service unavailable	For example, due to overloading or maintenance
