[変更イベント] には、アカウントで変更された内容の詳細が表示されます。作成オペレーションのレポートでは、新しいフィールド値がすべて返されます。更新オペレーションのレポートでは、新しい値と古い値の両方が返され、個々の変更を包括的に把握できます。
また、変更に使用されたクライアント タイプ（API やウェブ クライアントなど）と、変更を行ったユーザーも示されます。この情報は、ウェブ クライアントの変更履歴にも表示されます。

クエリ
変更リストは日付でフィルタする必要があります。期間は過去 30 日以内にする必要があります。
また、結果を最大 10,000 行に制限する LIMIT 句もクエリに含める必要があります。10,000 件を超える結果が必要な場合は、返された結果セットの最後のエントリのタイムスタンプをメモし、次のクエリで期間をその時間以降に設定して、中断したところから続行します。
変更が変更イベントの結果に反映されるまでに 3 分ほどかかることがあります。
次の例は、変更イベントを取得して処理する方法を示しています。変更を行ったユーザー、変更に使用したクライアント タイプ、変更の各フィールドの古い値と新しい値を特定します。

変更イベントには、ウェブ クライアントの変更履歴のすべての行が含まれない場合があります。変更履歴に似たビューの場合は、代わりに変更ステータス リソースを使用します。
変更イベント リソースは、個々の変更の詳細をドリルダウンすることを目的としています。変更された特定のフィールド値、変更を行ったユーザー、変更に使用されたクライアント タイプなどのデータを取得できます。ただし、アカウントに加えた変更がすべて変更イベントのエントリに対応しているわけではありません。
変更イベントで使用するために変更を記録する主なクライアント タイプには、次のようなものがあります。
- Google Ads API
