Automatically applied discounts / EDI integration

[SmeadDev]

Hello,

We have a unique situation that I'm hoping someone will be able to help with. We created a Back to School automatic discount for all items in our store, and while it's functioning fine on the order and checkout processes, the discount amount is not being sent back to our EDI integration with Shopify. Our EDI partner is TrueCommerce, which is integrated with D365.

We had TrueCommerce create a custom mapping where all discounts roll up at the order header rather than the line level. The field in TC that isn't being populated is called "Order Discount Code," however, when orders come in with a static discount code that customers have to manually type in at checkout, that field is populated with the discount.

I realize Shopify can't support all outside integrations, but I'm hoping someone in here will be able to shed some light on the underlying metadata differences between these two discount types and provide a clue that we can send back to TrueCommerce, as ultimately, this seems like it's an issue on their side.

Thanks!

Ben
