Each funnel button pushes a GA4-standard ecommerce event to the dataLayer with proper items, value, and currency parameters. The purchase event also includes a unique transaction_id.
GTM setup reminder: Update the GA4 Event - Purchase tag's Event Name to {{Event}}, and change its trigger to match the whitelist regex ^(view_item|add_to_cart|begin_checkout|purchase|gtm_purchase_test)$.
