Change Status provides a means to keep track of which resources have changed within an account over a given time period. If a resource had multiple changes during your given time period, then only the latest change is returned.
Use this service to determine if you need to sync your local values in your database with the values that changed during that given time period.
For example, if during a given time period you add and then update a given
campaign, only the change status for the UPDATE
(not for the ADD
) operation
is returned. If you move the end of the timeframe to before the update, then
you would see the ADD
operation.
If you want the complete field-by-field results with a detailed view similar to the Change History UI, use the Change Event service.
Change Status types
The Change Service currently tracks changes for the following resource types:
Resource type | Value | Resource type ID |
---|---|---|
Core Entities | ||
Ad group | AD_GROUP | 2 |
Ad group ad | AD_GROUP_AD | 3 |
Ad group bid modifier | AD_GROUP_BID_MODIFIER | 11 |
Ad group criterion | AD_GROUP_CRITERION | 4 |
Ad group feed | AD_GROUP_FEED | 12 |
Campaign | CAMPAIGN | 5 |
Campaign criterion | CAMPAIGN_CRITERION | 6 |
Feeds | ||
Campaign feed | CAMPAIGN_FEED | 9 |
Feed | FEED | 8 |
Feed item | FEED_ITEM | 10 |
Shared Sets | ||
Shared set | SHARED_SET | 17 |
Campaign shared set | CAMPAIGN_SHARED_SET | 18 |
Assets | ||
Asset | ASSET | 13 |
Customer asset | CUSTOMER_ASSET | 14 |
Campaign asset | CAMPAIGN_ASSET | 15 |
Ad group asset | AD_GROUP_ASSET | 16 |
Tracking of additional resource types are planned for future releases.
Determining resource type by ID
The Google Ads API may return rows with an UNKNOWN
resource type value for older API
versions. This means that the type is supported in a future version of the
Google Ads API, but was not fully supported at the time that your current version was
released.
When this happens, you can still determine the resource type of the row by
parsing the returned resource_name
.
The resource name format is:
customers/{customer_id}/changeStatus/{timestamp}-{resource_type_id}-{additional_ids}
There could be one or more additional IDs, separated by the -
character, but
the one that is relevant here is the resource_type_id
, the second ID after
the final slash. See the table above for a complete list of resource type IDs.
Getting changes
The list of changes can be filtered by date as well as by resource type. The
operation on a given resource will be one of
ADDED
,
CHANGED
,
or
REMOVED
.
You can retrieve the list of all changes for all resource types. The
returned resource_type
is the
field that changed. Any parent fields are also populated. For example, if the
ad_group_criterion
changed,
then the ad_group
field will also be
populated.
The query must filter on date within the past 90 days (and optionally time),
and must include a LIMIT
clause set to at most 10,000 results.

Keeping synchronized locally
Once the precise resource_name
is
retrieved, a new query with this resource name should be made to obtain all the
current values of the resource. The Change Status Service does not track the
specific resource's values that changed—only which resources changed.
Determining the difference between the prior and current values is the
responsibility of the calling program.
Checking a resource's change time
The service provides the
last_change_date_time
field to indicate when the most recent change to any given resource occurred.
Thus, the freshness of locally cached data can be compared with this field's
value to help determine whether local data is out of date.
Note that this field is also filterable, meaning it can be used in the
WHERE
clause of a Google Ads Query Language (GAQL) query. This enables the
ability to query for changes in resources that have occurred before or after a
given time.
For example, finding all changes that have occurred for a certain resource type within the last week can be accomplished with a GAQL predicate clause like:
... WHERE change_status.last_change_date_time DURING LAST_7_DAYS
