# Status Codes

You can import the `status` module from `fastapi`:

```python
from fastapi import status
```

`status` is provided directly by Starlette.

It contains a group of named constants (variables) with integer status codes.

For example:

* 200: `status.HTTP_200_OK`
* 403: `status.HTTP_403_FORBIDDEN`
* etc.

/// note | Hinweis

Einige Responsecodes (siehe nächsten Abschnitt) kennzeichnen, dass die Response keinen Body hat.

FastAPI erkennt dies und erstellt eine OpenAPI-Dokumentation, die zeigt, dass es keinen Responsebody gibt.

# Use Old 403 Authentication Error Status Codes { #use-old-403-authentication-error-status-codes }

Before FastAPI version `0.122.0`, when the integrated security utilities returned an error to the client after a failed authentication, they used the HTTP status code `403 Forbidden`.

# Usar los códigos de estado antiguos 403 para errores de autenticación { #use-old-403-authentication-error-status-codes }

Antes de FastAPI versión `0.122.0`, cuando las utilidades de seguridad integradas devolvían un error al cliente después de una autenticación fallida, usaban el código de estado HTTP `403 Forbidden`.
