HTTP 201 Created vs 506 Variant Also Negotiates

HTTP 201 (Created) is a 2xx Success response, while 506 (Variant Also Negotiates) is a 5xx Server 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, 506 means that the server has an internal configuration error: the chosen variant resource is configured to engage in content negotiation itself.
