Sample API's using DRF

Status code

• 200 OK – Everything is working
• 201 OK – New resource has been created
• 204 OK – The resource was successfully deleted
• 304 Not Modified – The client can use cached data
• 400 Bad Request – The request was invalid or cannot be served. The exact error should be explained in the error payload. E.g. „The JSON is not valid“
• 401 Unauthorized – The request requires an user authentication
• 403 Forbidden – The server understood the request, but is refusing it or the access is not allowed.
• 404 Not found – There is no resource behind the URI.
• 422 Un-processable Entity – Should be used if the server cannot process the entity, e.g. if an image cannot be formatted or mandatory fields are missing in the payload.
• 500 Internal Server Error – API developers should avoid this error. If an error occurs in the global catch blog, the stack-trace should be logged and not returned as response.
