Bu parametre o endpoint’i / *path operation*’ı oluşturmaz; fakat `/token` URL’sinin client’ın token almak için kullanması gereken URL olduğunu bildirir. Bu bilgi OpenAPI’de, dolayısıyla etkileşimli API dokümantasyon sistemlerinde kullanılır.

Birazdan gerçek path operation’ı da oluşturacağız.

//   - Defines how many S3 operations are executed parallel within one Repository Task Slot (and within one backup object

//     Optional value, default 64, range: 1-unlimited

//     Some of the Veeam products use Multi Delete operations. This setting can reduce how many objects are included in one

### コールバックの path operation を作成 { #create-the-callback-path-operation }

上で作成したのと同じ `APIRouter` を使って、コールバックの *path operation* を作成します。

見た目は通常の FastAPI の *path operation* と同じです:

* 受け取るボディの宣言（例: `body: InvoiceEvent`）が必要でしょう。
* 返すレスポンスの宣言（例: `response_model=InvoiceEventReceived`）も持てます。

   * equivalent to that of calling {@code put(k, v)} on this map once for each mapping from key
   * {@code k} to value {@code v} in the specified map. The behavior of this operation is undefined
   * if the specified map is modified while the operation is in progress.
   *
   * @since 12.0
