////

Wenn Sie mit einer *Pfadoperation* kommunizieren, die zwei HTTP-Header sendet, wie:

```
X-Token: foo
X-Token: bar
```

Dann wäre die Response:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

## Den Token zurückgeben

Die Response des `token`-Endpunkts muss ein JSON-Objekt sein.

Es sollte einen `token_type` haben. Da wir in unserem Fall „Bearer“-Token verwenden, sollte der Token-Typ "`bearer`" sein.

Und es sollte einen `access_token` haben, mit einem String, der unseren Zugriffstoken enthält.
