Configure Google Analytics App Tracking

To track engagement with mobile URLs, set up Google Analytics 4 (GA4) property tracking for your Marketing Cloud Engagement business unit.

Before you can set up tracking for supported mobile apps, ask your developer to configure the Firebase SDK, which supports logging custom campaign details to GA4.

From Engagement Setup, go to Data Management, and then click Parameter Management.
Click GA4 Property Tracking.
On the App tab, turn on tracking parameters.

You can’t configure the tracking parameters.
Save your changes.
