HTTP 201 Created vs 421 Misdirected Request

HTTP 201 (Created) is a 2xx Success response, while 421 (Misdirected Request) 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, 421 means that the request was directed at a server that is unable to produce a response for the combination of scheme and authority in the URI.
