HTTP Code 200 OK

200 OK is a standard successful HTTP server response. It means that the client’s request (e.g., from a browser) was successfully processed, and the server is delivering the requested data.

When is Code 200 used?

  • When loading a web page
  • When successfully receiving an API response
  • When processing a form or another HTTP request

What does Code 200 mean for the user?

The user receives content without errors, and the page or application functions properly. If Code 200 is accompanied by data, the browser or program processes and displays it to the user.
