Pydanticモデルの属性に対して宣言するのと同じ型を受け取るので、Pydanticモデルになることもできますが、例えば、`List[Item]`のようなPydanticモデルの`list`になることもできます。

FastAPIは`response_model`を使って以下のことをします:

* 出力データを型宣言に変換します。
* データを検証します。
* OpenAPIの *path operation* で、レスポンス用のJSON Schemaを追加します。
* 自動ドキュメントシステムで使用されます。

しかし、最も重要なのは:

* 出力データをモデルのデータに限定します。これがどのように重要なのか以下で見ていきましょう。

* `openapi_url`: die URL, unter welcher die HTML-Seite für die Dokumentation das OpenAPI-Schema für Ihre API abrufen kann. Sie können hier das Attribut `app.openapi_url` verwenden.
* `title`: der Titel Ihrer API.

You can reuse FastAPI's internal functions to create the HTML pages for the docs, and pass them the needed arguments:

* `openapi_url`: the URL where the HTML page for the docs can get the OpenAPI schema for your API. You can use here the attribute `app.openapi_url`.
* `title`: the title of your API.
* `oauth2_redirect_url`: you can use `app.swagger_ui_oauth2_redirect_url` here to use the default.

{* ../../docs_src/openapi_webhooks/tutorial001.py hl[9:13,36:53] *}

Die von Ihnen definierten Webhooks landen im **OpenAPI**-Schema und der automatischen **Dokumentations-Oberfläche**.

/// info

Das `app.webhooks`-Objekt ist eigentlich nur ein `APIRouter`, derselbe Typ, den Sie verwenden würden, wenn Sie Ihre Anwendung mit mehreren Dateien strukturieren.
