When Cartfunnel exports an order to Shopify, Cartfunnel sends the total discount value in the Order record. In your Shopify dashboard, within the Order details, you’ll see a special order attribute that indicates how much discount was applied to the order:
The discount value, although passed to Shopify, is not displayed. This isn’t something Cartfunnel can control as it’s the way Shopify handles the order record information on their system.
Each line item also has a discount value that can be associated with it. Cartfunnel does not currently populate the discount value on the line item record. The reason for this is that there are so many ways to attribute a discount to an order (eg. discount is only applied to one item but not another), the system treats the discount only at the order level.
