What Churney sends

• Predicted value events through the GA4 Measurement Protocol, tied to each user's app_instance_id.
• In Google Ads you import them as conversions and use them for target ROAS on app campaigns.
• With Firebase linked correctly, match rates typically run above 95%.

Web campaigns use the Google Ads API instead. See Connecting Google Ads to Churney.
