變更狀態

影片：狀態

變更狀態可讓您追蹤在特定時間範圍內，帳戶中有哪些資源發生變更。如果資源在指定時間範圍內有多項變更，系統只會傳回最新的變更。接著您可以判斷是否需要將本機資料庫值與在特定時間範圍內變更的值保持同步。

舉例來說，如果您在指定時間範圍內新增並更新特定廣告活動，系統只會傳回 UPDATE 的變更狀態，不會傳回 ADD 作業的變更狀態。如果您將時間範圍的結尾移至更新之前，應該會看到 ADD 作業。

如果您想要以類似「變更記錄」網頁的方式，以欄位為單位的完整欄位結果，請參閱變更事件一節。

重點： 並非所有變更狀態的資料列在變更事件中都有對應的詳細資料。詳情請參閱「變更事件限制」。

變更狀態類型

系統會追蹤下列資源類型，請注意，資源類型 ID 與 ChangeStatusResourceType 的列舉值索引不同。

資源類型	值	資源類型 ID
核心實體
廣告群組	AD_GROUP	2
廣告群組廣告	AD_GROUP_AD	3
廣告群組出價調節係數	AD_GROUP_BID_MODIFIER	11
廣告群組條件	AD_GROUP_CRITERION	4
廣告群組動態饋給	AD_GROUP_FEED	12
廣告活動	廣告活動	5
廣告活動條件	CAMPAIGN_CRITERION	6
動態饋給
廣告活動動態消息	CAMPAIGN_FEED	9
動態消息	資訊提供	8
動態饋給項目	FEED_ITEM	10
共用組合
共用組合	SHARED_SET	17
廣告活動共用組合	CAMPAIGN_SHARED_SET	18
素材資源
資產	素材資源	13
客戶素材資源	CUSTOMER_ASSET	14
廣告活動素材資源	CAMPAIGN_ASSET	15
廣告群組素材資源	AD_GROUP_ASSET	16

根據 ID 判斷資源類型

Google Ads API 可在較舊版本的 API 中傳回含有 UNKNOWN 資源類型值的資料列，表示日後的 Google Ads API 版本支援該類型，不過在目前版本發布時並未提供完整支援。發生這種情況時，您還是可以透過剖析傳回的 resource_name，判斷資料列的資源類型。

資源名稱格式為：

customers/{customer_id}/changeStatus/{timestamp}-{resource_type_id}-{additional_ids}

也可以有一或多個以 - 字元分隔的 ID，但相關的 ID 與 resource_type_id，也就是最後一個斜線後面的第二個 ID。上表會列出所有資源類型 ID。

擷取變更

您可以依日期和資源類型來篩選變更清單。對特定資源的作業是 ADDED、CHANGED 或 REMOVED 其中之一。

您可以擷取所有資源類型的所有變更清單。傳回的 resource_type 是已變更的欄位。系統也會在所有父項欄位填入資料。舉例來說，如果 ad_group_criterion 有所變更，ad_group 欄位也會填入資料。

變更最多可能需要 3 分鐘才會反映在變更狀態結果中。

查詢必須篩選過去 90 天內的日期 (選用)，而且必須納入設為最多 10,000 筆結果的 LIMIT 子句。

在本機同步

擷取準確的 resource_name 後，請使用這個資源名稱的新查詢，以取得資源目前的所有值。系統不會追蹤特定資源的變更值變更狀態，只會追蹤哪些資源已變更。判斷先前和目前值之間的差異，由呼叫程式負責。

變更時間

last_change_date_time 欄位表示資源最近的變更發生時間。因此，您可以將本機快取資料與這個欄位的值進行比較，以協助判斷本機資料是否過時。

請注意，這個欄位也可供篩選，代表可用於 Google Ads 查詢語言 (GAQL) 查詢的 WHERE 子句，方便您查詢在特定時間之前或之後發生的資源變更。

舉例來說，您可以使用下列 GAQL 述詞子句，找出上週特定資源類型發生的所有變更：

WHERE change_status.last_change_date_time DURING LAST_7_DAYS
