If you're still using Google Ads API v18, you’re now racing against a hard deadline: on August 20, 2025, v18 will be officially sunset, meaning all API calls using it will start failing—immediately halting any automated ad workflows that rely on it.
How Urgent Is the Migration?
It’s incredibly urgent. If you're still on v18 as the deadline approaches, your API integrations will break leading to:
Automations failing (campaign setup, reporting, bid updates)
Data feeds stopping (reports, dashboards, tools)
Potential underperformance or loss of real-time control over your ad accounts
What Could Break if You Delay?
API Requests using v18 will fail outright, rendering any connected systems non-functional
Campaigns may miss automations (e.g., pause low performers, adjust bids)
Reporting and dashboards will lose data flow
Any tool, custom scripts, CRMs, reports, using v18 will cease to work
What Should You Do Now?
Immediately check your API usage in Google Cloud Console → APIs & Services → Google Ads API → Metrics tab to see if v18 is being used.
Choose a newer, supported version—best practice is to move to the latest (e.g., v19 or newer)
Review Google's migration guides and release notes to update your client library and refactor any deprecated endpoints or data structures.
Test thoroughly, make sure your calls, reports, and processes still run correctly before the August deadline
The countdown is on. Migration from v18 to a newer version is not optional, it’s essential. Any delay will risk campaign automation, reporting, and operations. If your systems depend on API connectivity, start migrating now to ensure seamless transition and uninterrupted ad management.
