1. Get the IDs
In Google Ads: Tools → Conversions → New conversion action → Import → API.
- Customer ID: top-right corner, format
XXX-XXX-XXXX(enter it without dashes). - Conversion ID and Conversion Label: from the created conversion action page.
- OAuth token: generate it via the Google OAuth Playground with the scope
https://www.googleapis.com/auth/adwords.
2. Fill it in in DataNostro
Dashboard → Platforms → Google Ads — fill in all 4 fields.
3. Test it
After a test event, the conversion appears in Google Ads within 3 hours (not in real time). For quick debugging use Tools → Conversions → click "Diagnostics".
