Standard HTTP Status Codes

To indicate "SUCCESS/FAILURE" of API calls, the following standard HTTP status codes are used. For every "SUCCESS/FAILURE" response, the response header contains the HTTP code and the response body contains detailed information about the success response or the error.

HTTP Status Codes	Message	Details
200	Success	Success with response body. Most GET requests will receive this response. If no data, an empty response body will be sent.
201	Created	Success with response body. Used with POST URIs where a resource is created in DB.
204	Success	Success with no response body.
400	Bad Request	The server cannot or will not process the request due to  a client error such as malformed request syntax, invalid request message framing, or deceptive request routing. To be used if URI syntax is not correct such as wrong format in q query.
401	Unauthorized	User not authorized.
403	Forbidden	Operation not permitted for the user.
404	Not found	Request resource not found.
405	Method not allowed	HTTP action not allowed for the requested API.
406	Not acceptable	The endpoint does not support the response format specified in the request Accept header.
415	Unsupported media type	The endpoint does not support the format of the request body.
