# Status Code

HTTP status codes are divided into five categories –

* **Informational (100-199):** The server has received part of the request and expects more information.
* **Successful (200-299):** The request was successful, and the server has returned the requested data.
* **Redirection (300-399):** The requested resource has been moved elsewhere.
* **Client Error (400-499):** There is an issue with the client's request.
* **Server Error (500-599):** The server encountered an issue while processing the request.
