Wondering if anyone has successfully implemented sending Shopify Customer ID to GA4? Our store is using the Google Sales Channel GA4 integration, but we also have GTM for gathering some additional events that aren’t tracked through the GSL GA4 integration. User_login event, for example, we began tracking to segment current customers out of certain ads. Trying to find a good example of how to also capture the Shopify customer ID to pass to GA4 with transactions/these user_login events. Currently, GA4 just uses device ID as the effective ID.
