Change Status 提供了一种跟踪特定时间段内账号中哪些资源发生了更改的方法。如果资源在指定时间段内发生了多次更改，则系统只会返回最新的更改。然后，您可以确定是否需要将本地数据库值与相应时间段内发生变化的值同步。
例如，如果您在给定时间段内添加了给定广告系列，然后更新了该广告系列，则系统只会返回 UPDATE 操作的更改状态，而不会返回 ADD 操作的更改状态。如果您将时间范围的结束时间移至更新之前，则会看到 ADD 操作。
如果您希望查看按字段显示的完整结果，并以类似于“更改历史记录”网页的详细视图查看，请参阅更改事件。
Change Status 类型
系统会跟踪以下资源类型。请注意，资源类型 ID 不同于 ChangeStatusResourceType 的枚举值编号。
| 资源类型 | 值 | 资源类型 ID |
|---|---|---|
| 核心实体 | ||
| Google Ads 广告组 | AD_GROUP | 2 |
| 广告组广告 | AD_GROUP_AD | 3 |
| 广告组出价调节系数 | AD_GROUP_BID_MODIFIER | 11 |
| 广告组条件 | AD_GROUP_CRITERION | 4 |
| 广告组 Feed | AD_GROUP_FEED | 12 |
| 素材资源组 | ASSET_BUNDLE | 19 |
| 广告系列 | 竞选活动 | 5 |
| 广告系列条件 | CAMPAIGN_CRITERION | 6 |
| Feed | ||
| 广告系列 Feed | CAMPAIGN_FEED | 9 |
| 动态 | FEED | 8 |
| Feed项 | FEED_ITEM | 10 |
| 共享集 | ||
| 共享集 | SHARED_SET | 17 |
| 广告系列共享集 | CAMPAIGN_SHARED_SET | 18 |
| 资产 | ||
| 素材资源 | 资产 | 13 |
| 客户素材资源 | CUSTOMER_ASSET | 14 |
| 广告系列素材资源 | CAMPAIGN_ASSET | 15 |
| 广告组素材资源 | AD_GROUP_ASSET | 16 |
根据 ID 确定资源类型
对于较低的 API 版本，Google Ads API 可能会返回具有 UNKNOWN 资源类型值的行，这意味着该类型在未来版本的 Google Ads API 中受支持，但在当前版本发布时尚不完全受支持。在这种情况下，您仍然可以通过解析返回的 resource_name 来确定行中的资源类型。
资源名称格式为：
customers/{customer_id}/changeStatus/{timestamp}-{resource_type_id}-{additional_ids}
可能还有一个或多个其他 ID（以 - 字符分隔），但相关的 ID 是 resource_type_id，即最后一个斜线后面的第二个 ID。上表列出了所有资源类型 ID。
检索更改
您可以按日期和资源类型过滤更改列表。给定资源上执行的操作是 ADDED、CHANGED 或 REMOVED 中的一项。
您可以检索所有资源类型的所有更改的列表。返回的 resource_type 是已发生更改的字段。此外，系统还会填充所有父级字段。例如，如果 ad_group_criterion 发生更改，则系统也会填充 ad_group 字段。
更改最长可能需要 3 分钟才能反映在更改状态结果中。
查询必须按过去 90 天内的日期（可选）和时间进行过滤，并且必须包含一个设置为最多 10,000 个结果的 LIMIT 子句。

在本地同步
检索到精确的 resource_name 后，应该使用此资源名称创建一个新查询，以获取资源的所有当前值。系统不会跟踪特定资源的哪些值发生了更改，而只会跟踪哪些资源发生了更改。至于先前值和当前值之间的差异，均由调用程序负责确定。
更改时间
last_change_date_time 字段表示资源的最近一次更改发生的时间。因此，您可以将本地缓存数据的新鲜度与此字段的值进行比较，以帮助确定本地数据是否已过时。
请注意，此字段还可过滤，这意味着您可以在 Google Ads 查询语言 (GAQL) 查询的 WHERE 子句中使用此字段，以查询在指定时间之前或之后发生的资源更改。
例如，您可以使用以下 GAQL 谓词子句查找过去一周内发生的特定资源类型的所有更改：
WHERE change_status.last_change_date_time DURING LAST_7_DAYS
