# OpenAPI の拡張 { #extending-openapi }

生成された OpenAPI スキーマを変更する必要がある場合があります。

このセクションではその方法を説明します。

## 通常のプロセス { #the-normal-process }

通常（デフォルト）のプロセスは次のとおりです。

`FastAPI` アプリケーション（インスタンス）には、OpenAPI スキーマを返すことが期待される `.openapi()` メソッドがあります。

アプリケーションオブジェクトの作成時に、`/openapi.json`（または `openapi_url` に設定したパス）への path operation が登録されます。

これは単に、アプリケーションの `.openapi()` メソッドの結果を含む JSON レスポンスを返します。
