Setup a Data Stream
After creating your new property, you’ll need to start populating it with data for the dashboards and reports to begin showing. To do this, you’ll need to setup a Data Stream.
GA4 was designed to integrate data from various sources, such as a brand’s website and app, and unify them within a single platform. The data coming from these various sources are known within GA4 as Data Streams. For websites, you’ll generally only need one Data Stream no matter how many websites or domains are sending data to this property.
