「變更事件」會詳細說明帳戶中發生的變更。針對建立作業製作報表時，系統會傳回所有新的欄位值；針對更新作業製作報表時，系統會傳回新的值和舊值，讓您全面掌握個別變更。
此外，系統也會指出用於變更的用戶端類型 (例如 API 或網頁用戶端)，以及變更的使用者，前提是這些資訊也必須顯示在網頁用戶端的變更記錄中。
變更事件類型
請參閱 ChangeEventResourceType 的資源類型清單。
查詢
變更清單必須按日期篩選。日期範圍必須是過去 30 天內。
查詢也必須包含 LIMIT 子句，將結果限制在最多 10,000 列。如果您想取得超過 10,000 個結果，請記下傳回結果集最後一個項目的時間戳記，然後在下一次查詢中將日期範圍設為從該時間開始，以便繼續查詢。
變更最多可能需要三分鐘才會反映在變更事件結果中。
以下範例說明如何擷取變更事件並加以處理，包括判斷變更者、他們用來變更的用戶端類型，以及變更中每個欄位的舊值和新值：

變更事件可能不會包含網頁用戶端中「變更記錄」中的每個資料列。如要查看類似變更記錄的畫面，請改用變更狀態資源。
變更事件資源可用於深入探討個別變更的詳細資料。您可以擷取資料，例如已變更的特定欄位值、變更者，以及用於變更的用戶端類型。不過，並非所有帳戶變更都會有對應的變更事件項目。
以下是一些會記錄變更以便搭配變更事件使用的重點用戶端類型：
- Google Ads API
- Google Ads 網頁用戶端
