更改状态

视频：状态

“更改状态”提供了一种 在给定时间段内，账号中有哪些资源发生了变化。如果 某资源在给定时间段内发生了多次更改，之后只有 返回最新的更改。然后，您可以确定是否需要同步 本地数据库值与时间段内发生更改的值。

例如，如果您在某个给定时间段内添加并更新了某个给定的 广告系列，只更改 UPDATE 的更改状态，而不更改 ADD 的更改状态 操作。如果您将时间范围的结束时间移至 则会看到 ADD 操作。

如果您希望按字段查看完整结果，并且详细视图与 更改历史记录网页，请参阅更改事件。

按 ID 确定资源类型

对于较早的时间，Google Ads API 可以返回具有 UNKNOWN 资源类型值的行 API 版本，表示该类型在 的未来版本中受支持 ，但当时您的当前版本未得到完全支持。 发布。在这种情况下，您仍然可以确定 行。resource_name

资源名称格式为：

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

可以还有一个或多个其他 ID（以 - 字符分隔），但是 相关的第二个 ID 是 resource_type_id，即第二个 ID 最后一个斜杠。上表列出了所有资源类型 ID。

检索更改

可以按日期和资源类型过滤更改列表。通过 操作属于 ADDED, CHANGED, 或 REMOVED。

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 已更改。系统也会填充所有父级字段。例如，如果 ad_group_criterion已更改， 那么 ad_group 字段也是 填充。

更改最长可能需要 3 分钟才能反映在更改状态中 结果。

查询必须过滤过去 90 天内的某个日期，并且可以选择 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

获取确切的 resource_name 后， 应使用此资源名称创建一个新查询，以获取所有 资源的当前值系统不会跟踪特定更改的状态 资源已更改的值 - 仅限已更改的资源。正在确定 先前值和当前值之间的差异由 调用程序。

更改时间

last_change_date_time 字段指示对资源进行最近一次更改的时间。因此， 可以将本地缓存数据的新鲜度与此字段的值进行比较， 确定本地数据是否已过期。

请注意，此字段也可过滤，这意味着它可在 WHERE 中使用。 子句，从而允许您查询 在指定时间之前或之后发生的资源更改。

例如，查找特定资源类型发生的所有更改 可以使用以下 GAQL 谓词完成搜索 子句：

WHERE change_status.last_change_date_time DURING LAST_7_DAYS
