Can not provide tax information on Shopify Stripe checkout via StoreFront API

Technical Q&A
1

I try to implement a Shopify Stripe checkout via StoreFront API. The steps performed for this are:

  1. Creating checkout via this endpoint
  2. Getting Stripe token from Stripe API
  3. Completing checkout via this endpoint

The problem is that tax information is not encountered in the resulting order.

I can not pass total amount(including tax amount) in the 3rd step as I get TOTAL_PRICE_MISMATCH error from Shopify. So I have to pass sub total amount. And this causes tax information not to be included in the resulting order.

Can anyone help me to solve this problem?
