# HTML Status Codes

When a Catchpoint test makes a request to an HTTP server, it receives a response which includes a Status Code. The standard code when a request is successful is **200 OK**. There are many other codes, including various error codes that can help you understand why a request failed. The tables below list the standard HTML status codes and describe the meaning of each.

(Response usually also includes the protocol the server is switching to)</p></td> </tr> <tr class="even"> <td><p><strong>103 Early Hints</strong></p></td> <td><p><span>The server is returning some response headers before returning the final HTTP message</span></p></td> </tr> </tbody> </table>
