Steps
Authenticate with OAuth2 and a developer token against the Google Ads API.
Query the change_status resource via GoogleAdsService.SearchStream filtered to last_change_date_time within the past 30 days.
For each changed resource, query the change_event resource to get field-level before/after values and the user who made the change.
Join change_event rows back to the campaigns/ad groups/ads you're auditing.
Apply the required LIMIT clause (max 10,000 rows) and issue additional queries if you exceed the row cap.
Known gotchas
change_status only signals that something changed and expects you to re-fetch the resource; not every change_status row has a matching change_event row.
Data is retained for only the past 30 days, and a change can take up to about three minutes to appear in change_event results.
GAQL requires an explicit LIMIT (max 10,000) on these queries or the request is rejected outright.
