Which status code indicates a resource was successfully created?

Which status code indicates a resource was successfully created?

• A. 201 Created
• B. 200 OK
• C. 204 No Content
• D. 400 Bad Request

Answer: (A)

When a request results in creating a new resource, the server uses the 201 Created status. This code signals that the operation succeeded specifically because a new resource has been created, and it often includes a Location header with the URL of the new resource (and may return a representation of it in the body). The other codes don’t convey creation. 200 OK means the request succeeded and typically returns data, but it doesn’t indicate that a new resource was created. 204 No Content means the request succeeded but there’s no content to send back, which isn’t about creating something new. 400 Bad Request indicates the client sent invalid data or the request couldn’t be processed. So the code that best communicates successful creation is 201 Created.
