Tips

  • HTTP status codes indicate the result of a client request to a web server, helping you understand whether a request succeeded, failed, or requires additional action.
  • You can see status codes in your browser's developer tools (Network tab), server logs, API responses, and HTTP headers when making web requests.
  • Informational (1xx): These responses indicate that the request was received and understood. The server is continuing to process the request.
  • Success (2xx): The request was successfully received, understood, and accepted. Common codes include 200 OK and 201 Created.
  • Redirection (3xx): Further action must be taken to complete the request, such as following a redirect to a new URL.
  • Client Error (4xx): The request contains bad syntax or cannot be fulfilled. Examples include 404 Not Found and 401 Unauthorized.
  • Server Error (5xx): The server failed to fulfill a valid request due to an error on the server side, such as 500 Internal Server Error.
