Once AppsFlyer is connected, Rey sends attribution-ready data so you can measure which campaigns bring valuable users to your app.

​
Events Rey tracks automatically

AppsFlyer attribution requires an app-store installation. It does not work for apps tested only in the Rey preview environment.

​
Send custom events

Use a Track Event action in Rey to capture moments that matter to your app, such as completing onboarding, making a purchase, or reaching a key feature.
1

Select the component

Choose the component you want to track, such as a button.
2

Open Logic

In the property toolbar, open the Logic tab, choose a trigger, and add a Track Event action.
3

Name the event

Enter the event name and any properties you want to include.
Use consistent snake_case event names across iOS and Android. AppsFlyer treats Purchase_Completed and purchase_completed as different events.

​
View attribution data

View installs by campaign, cost per install, return on ad spend, and in-app event counts in your AppsFlyer dashboard. Configure OneLink deep links in AppsFlyer under Engagement & Deep Linking → OneLink. AppsFlyer also supports Apple’s SKAdNetwork (SKAN); configure SKAN conversion values in AppsFlyer when needed.
