HTTP 201 Created vs 203 Non-Authoritative Information

Both HTTP 201 (Created) and 203 (Non-Authoritative Information) belong to the 2xx Success category. 201 indicates that the request succeeded and a new resource was created. Typically returned after POST or PUT requests that create a new entity. Meanwhile, 203 means that the response payload has been modified by a transforming proxy from the origin server's 200 response.
