Hi,
We’re reaching out to address a critical issue regarding the order total amount in delivery customization. (Delivery customization is an extension)
As per the documentation provided by Shopify, we understand that the total amount parameter should include both the subtotal and tax amount. However, we have noticed that we are only receiving the subtotal amount, without the inclusion of tax.
That does sound unusual - just to test, are you able to recieve values for totalTaxAmount? As a temporary measure you may be able to do calculations to display the full total?
We already passed the same query as you suggested, but it still gives an empty object even if the tax amount is on the checkout page.
Could you please suggest another way?
