在 FastAPI 中，透過 OpenAPI，你可以定義這些 webhook 的名稱、你的應用將發送的 HTTP 操作類型（例如 `POST`、`PUT` 等），以及你的應用要發送的請求主體。

這能讓你的使用者更容易實作他們的 API 以接收你的 webhook 請求，甚至可能自動產生部分他們自己的 API 程式碼。

/// info

Webhook 功能自 OpenAPI 3.1.0 起提供，FastAPI `0.99.0` 以上版本支援。

///

## 含有 webhook 的應用 { #an-app-with-webhooks }

建立 FastAPI 應用時，會有一個 `webhooks` 屬性可用來定義 webhook，方式與定義路徑操作相同，例如使用 `@app.webhooks.post()`。

Webhook は OpenAPI 3.1.0 以上で利用可能で、FastAPI `0.99.0` 以上が対応しています。

///

## Webhook を持つアプリ { #an-app-with-webhooks }

**FastAPI** アプリケーションを作成すると、`webhooks` という属性があり、ここで *path operations* と同様に（例: `@app.webhooks.post()`）*webhook* を定義できます。

{* ../../docs_src/openapi_webhooks/tutorial001_py310.py hl[9:12,15:20] *}

定義した webhook は **OpenAPI** スキーマおよび自動生成される **ドキュメント UI** に反映されます。
