HTTP 201 Created vs 401 Unauthorized

HTTP 201 (Created) is a 2xx Success response, while 401 (Unauthorized) is a 4xx Client Error response. 201 indicates that the request succeeded and a new resource was created. Typically returned after POST or PUT requests that create a new entity. In contrast, 401 means that the request requires user authentication. The response includes a WWW-Authenticate header indicating the authentication scheme.
