It is ridiculous that there is no way for Shopify apps to get override tax from Shopify API.
From Shopify's general tax configuration, we can only get one tax for each country,
but what happens when some countries have different tax values for different product categories. For example, in Germany there are two tax values 7% and 19%.
This is very important for our customers. Because our app should generate order in Shopify-shop with tax of existing products.
I have already read this post, but I could not believe that there is no solution for this so important feature.
