Selling products online is subject to different types of taxes that may vary according to inventory location, shipping addresses, and, of course, the product itself. For some stores, especially those that operate in a B2B model, tax calculations can be so complex that it is necessary to use an external tax calculation provider.

For such cases, it is possible to build an integration that allows a store to send Checkout information to an external tax calculation API. The external API should then respond with the appropriate taxes and values that apply to the purchase.
