After watching this video https://stape.io/facebook-conversion-api-for-shopify/ it explains how to use universal GA (method what we are using) and GTM server to create events for page view, view content & add to cart. Great.
I’m on Shopify Plus though. Not sure if we need to grab more data layers and build triggers in GTM for the initiate checkout, add payment info and purchase (confirmation) pages also?
Thanks very much
