Explanation

301 (Moved Permanently) is a redirect status code - it tells the client the resource has moved to a new URL permanently, which has nothing to do with resource creation. When a REST API successfully creates a resource, it returns one of the 2xx success codes: 201 Created (the most semantically correct, indicating the resource was created and often includes a Location header pointing to it), 200 OK (acceptable when the server returns the created resource in the response body), or 202 Accepted (used when creation is asynchronous - the request was accepted but processing isn't complete yet). A helpful memory tip: 3xx codes are always about redirection, never about success or failure of an operation - if you see a 3xx in a creation context, it's wrong by definition.
