We have an app that returns shipping cost and duties/taxes real time during checkout. However, we observed that details we receive from Shopify to quote rates does not include discounted price.
The buyer is applying a discount code at checkout, still Shopify sends actual item price while hitting our app for rates. This is resulting in calculating duties/taxes on higher price than the actual price paid by the buyer.
We need discount price details to quote duties/taxes correctly.
