Google wants revenue events for tROAS. What's the usual way to send them from the app?
Our App campaigns are on target CPA and we want to try target ROAS. Do purchase values go from the app SDK, our server, or the MMP?
Answer from the Linkrunner team
Check the volume first. Google's guidance is to start on Maximise conversions or target CPA and switch to target ROAS once you have roughly 30 conversions in 30 days, with a dynamic value on every revenue event. Google's bidding page also says target ROAS needs the Google Analytics for Firebase SDK, with events from Firebase or Google Play codeless conversions, so check that against your setup. For MMP events, Google's third-party app analytics integration replaces the old postback URLs; keep the conversion actions in Google Ads one for one with your MMP's events, and import new ones early, since they only count from the import date. In Linkrunner, send purchases with capturePayment in the app or the server API, using one source per payment, then turn on Send Revenue for the mapped Google Ads event with your chosen currency.
