Якщо Ви взаємодієте з цією операцією шляху, надсилаючи два HTTP-заголовки, наприклад:

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

Відповідь буде така:

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

## Підсумок

Оголошуйте заголовки за допомогою `Header`, використовуючи той самий підхід, що й для `Query`, `Path` та `Cookie`.

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"
    ]
}
```

## Zusammenfassung

Deklarieren Sie Header mittels `Header`, auf die gleiche Weise wie bei `Query`, `Path` und `Cookie`.
