Hey I just wanted to make sure that I was doing this correctly. In order to calculate tax on an order - the way to do it would be to take an item, manually subtract any discounts, modifiers, etc. And then manually take the tax amount for each line item & calculate the tax amount owed. And thats the total amount? Is that Correct? There is pre-calculated response out of the API that is the generated tax amount on line items which would be the tax rate of that item times the amount?
