變更狀態可讓您追蹤帳戶在特定時間範圍內的變更資源。如果資源在指定時間範圍內有多次變更，系統只會傳回最新的變更。接著，您可以決定是否需要將本機資料庫值與在該時間範圍內變更的值同步。
舉例來說，如果您在特定時間範圍內新增特定廣告活動，然後再更新該廣告活動，系統只會傳回 UPDATE 的變更狀態，而不會傳回 ADD 作業的狀態。如果將時間範圍的結束時間移至更新前，就會看到 ADD 作業。
如要取得完整的欄位結果，並以類似變更記錄網頁的詳細檢視畫面查看，請參閱「變更事件」。

根據 ID 判斷資源類型
Google Ads API 可針對舊版 API 傳回具有 UNKNOWN 資源類型值的資料列，這表示該類型在 Google Ads API 的未來版本中受支援，但在您目前的版本發布時並未完全支援。在這種情況下，您仍可透過剖析傳回的 resource_name，判斷資料列的資源類型。
資源名稱格式如下：
customers/{customer_id}/changeStatus/{timestamp}-{resource_type_id}-{additional_ids}
可能會有一或多個額外 ID，以 - 字元分隔，但相關的 ID 是 resource_type_id，也就是最後一個斜線後的第二個 ID。上表列出所有資源類型 ID。
擷取變更
變更清單可依日期和資源類型篩選。對特定資源執行的作業為 ADDED、CHANGED 或 REMOVED。
您可以擷取所有資源類型的所有變更清單。傳回的 resource_type 是變更的欄位。所有父項欄位也會填入資料。舉例來說，如果 ad_group_criterion 有變更，系統也會填入 ad_group 欄位。
變更最多可能需要 3 分鐘才能反映在變更狀態結果中。
查詢必須篩選過去 90 天內的日期 (可選) 和時間，且必須包含 LIMIT 子句，且最多只能傳回 10,000 個結果。

在本機同步
擷取精確的 resource_name 後，請使用此資源名稱建立新的查詢，取得資源的所有目前值。系統不會追蹤特定資源的變更值，只會追蹤哪些資源已變更。決定先前值和目前值之間的差異，是呼叫程式的責任。
變更時間
last_change_date_time 欄位會指出資源最近一次變更的時間。因此，您可以將本機快取資料的最新狀態與這個欄位的值進行比較，藉此判斷本機資料是否已過時。
請注意，這個欄位也支援篩選功能，也就是說，您可以在 Google Ads 查詢語言 (GAQL) 查詢的 WHERE 子句中使用這個欄位，查詢指定時間前後資源的變更。
舉例來說，您可以使用下列 GAQL 預設子句，找出過去一週內特定資源類型發生的所有變更：
WHERE change_status.last_change_date_time DURING LAST_7_DAYS
