Goal

How to implement external tax calculation webhook if the tax amount depends on payment method? There are following two issues in this scenario:

1. Timing

Normally tax is calculated before payment method is selected. Since the tax depends on payment method, the actual tax can only be calculated after payment method is selected.

2. Pass payment method to external tax calculation webhook

According to this webhook's doc at https://docs.oracle.com/en/cloud/saas/cx-commerce/22c/cxocc/op-ccadmin-v1-webhook-externaltaxcalculation-post.html, payment info is not passed to this webhook.

This article will describe the solution for the above issues.
