200 OK
The HTTP 200 OK successful response status code indicates that a request has succeeded.
A 200 OK response is cacheable by default.
A 200 OK response has a different meaning and format depending on the HTTP request method.
Here's how they vary for different methods:
GET: A resource was retrieved by the server and included in the response body.POST: An action succeeded; the response has a message body describing the result.HEAD: Identical toGET, except there is no message body.TRACE: The response has a message body containing the request as received by the server.
Although possible, successful PUT or DELETE requests often do not result in a 200 OK response.
It is more common to see 201 Created if the resource is uploaded or created for the first time, or 204 No Content upon successful deletion of a resource.
