We are selling some products through upsell. We already put some tracking code in the Post Purchase box.
But those are not firing when someone lands on the post purchase page or after the initial offer. After debugging with making test purchase we found out that Shopify is not pushing a special global variable which is supposed to contain the order details. We are talking about this variable:
There is no order details on window.Shopify.
Therefore even though in their reference guide it's promised that they will push the order details on this global variable, we are are unable to retrieve this data from this variable.
