At a glance: Setup In-App Purchase revenue event to connect IAP revenue data to Cost Center. This is an important metric allowing you to analyse IAP revenue on game level via Level Analytics.
Cost Center gets IAP revenue from Firebase via default in_app_purchase event. If this event is not available for your app, you can:
1. Manually track IAP revenue into an event named iap_sdk
2. Update Cost Center’s configuration in Your App > App Settings > Advanced > IAP Event
