Event page views and registrations flow into your Google Analytics or Google Ads account.
Connect Google Analytics 4 and Google Ads to your event pages. You paste your property ID, and views and registrations go to your account, not ours.
We send payments to Google from the browser, at the moment the person returns from the bank's payment page. If they close the tab before the bank confirms the payment, that purchase will not reach Google Ads. So the number of payments in Google may be slightly lower than the real one; in Meta it is exact, because payments go there from our server.
Google Ads and Google Analytics are different accounts with different IDs. An AW- tag is Google Ads, and it needs a conversion label. A G- or GT- tag is Analytics: it has no labels, so leave the label field empty.
