GA4/UA Ecommerce transitional APIโ€‹

note

Available from version 3.10.

If you already use Google Analytics 4 ecommerce or Universal Analytics Enhanced Ecommerce to collect information about the shopping behavior of your users, we have prepared a way to quickly implement Snowplow Ecommerce without making many changes on your current setup.

The transitional API that we provide, depends on the standardized dataLayer structure for both Google Analytics ecommerce implementations. This would make it easier for the transition to happen either through Google Tag Manager, which has more control over the dataLayer, or custom code that uses the standard ecommerce structures.
