The following information is useful for understanding how GA4 DataLayer events and data are associated with Eulerian DataLayer data.
What events are measured?
Global Data
The following global parameters are always provided to each call sent as long as they exist in the original datalayer:
o page_location mapped to url
o page_referrer mapped to rf
o screen_resolution mapped to ss

o user_agent mapped to ereplay-ua
o client_id mapped to euidl

WARNING
By configuring server-side data collection like this, you will lose all access to the original web browser. This means that some features of the Eulerian Marketing Platform will not be available due to server-side integration, for example, but not limited to:
Heatmap
Client-side TMS
Identity synchronization for IdGraph, CookieSync, etc.
Real-time access to the user's current status via the JavaScript client-side API
Privacy Sandbox Integration
Client Hints Management
