We are Webgility and have mutual customers. We are consuming the Shopify order/refund download API in our Webgility application.
Our mutual customers are experiencing an issue while downloading the Orders and their refunds. As we checked in API response and we are getting Order with the Tax amount of 1.47 but in its refunds Tax amount is less, that is 1.04 but on the store is showing similar to the orders.
I am attaching the screenshot of the store and response of the API, Could you please check and help us to resolve the customer issue on priority.
It looks like the difference of ($0.43) between the total_tax in the refund_line_items ($1.04) and the total tax on the order ($1.47) is due to the difference in tax on the shipping label.
