200 OK
Description
The 200 OK status code indicates that the request has succeeded. The meaning of success depends on the HTTP method used:
- GET: The resource has been fetched and transmitted in the message body.
- HEAD: The representation headers are included in the response without any message body.
- PUT or POST: The resource describing the result of the action is transmitted in the message body.
- TRACE: The message body contains the request message as received by the server.
This is the standard response for successful HTTP requests and is the most common status code for a successful web request.
