**Examples**: - `200 OK` - `201 Created` - `204 No Content`

3xx: Redirection 🔄

Further action is required to complete the request.

Redirection
**Examples**: - `301 Moved Permanently` - `302 Found` - `307 Temporary Redirect`

4xx: Client Error ❌

The request contains an error.

Client_Error
**Examples**: - `400 Bad Request` - `401 Unauthorized` - `404 Not Found` - `429 Too Many Requests`

5xx: Server Error ⚠️

The server failed to fulfill an apparently valid request.

Server_Error
**Examples**: - `500 Internal Server Error` - `502 Bad Gateway` - `503 Service Unavailable`
