Where it goes

Paste it into Destinations → Google Analytics 4 → Measurement ID, then save. On container export, it is wired into the GA4 tag for you.

Measurement ID vs Stream ID

The Measurement ID starts with G-. The numeric Stream ID shown next to it is a different value — the extension needs the G- Measurement ID.

Verify it is collecting

After importing the container, open GA4 → Admin → DebugView (or Reports → Realtime) and browse your storefront in GTM Preview mode. Events should appear within a few seconds.
