}Authorizations
すべてのリクエストは API キーで認証します：Authorization: Bearer {API_KEY}。アプリのエンドポイントにはアプリの API キーを、ナレッジのエンドポイントにはナレッジベースの API キーを使用します（Dify API クイックスタート）。
キーはサーバーサイドで保管し、クライアントコードには決して埋め込まないでください。キーが欠落または無効なリクエストは HTTP 401（unauthorized）で失敗します。
Headers
この削除リクエストを識別する必須の値です。同じ API キーで同じ冪等キーと同じリクエストを再送信すると、元のジョブが 202 で返されます。別のリクエストや別の API キーで同じキーを再利用すると 409 が返ります。前後に空白を含まない、印字可能な ASCII 文字を使用してください。
Required string length:
8 - 255Path Parameters
ナレッジベース ID です。ナレッジベースの API アクセス ダイアログに表示されるサービス API エンドポイントの最後のセグメント（…/knowledge-fs/spaces/<knowledge base ID>）です。アドレスバーでは /datasets/new/ の後のセグメントです。
Query Parameters
cascade は、ソースが生成したドキュメントも削除します。keep はそれらのドキュメントを残します。残したドキュメントは削除ジョブの実行中は非表示になり、完了すると source_id が null になった状態で再び表示されます。以後は更新されません。
keep で削除する前に、ドキュメントファイル一覧を取得 で、この source_id を持つファイルの ID を保存してください。削除が完了すると、それらのファイルの source_id は null になります。
Available options:
cascade, keep Body
application/json
正規化後のリクエストは、UTF-8 で 32,768 バイト以内に収める必要があります。リクエストサイズの制限 を参照してください。
