Scenario 1: Full or Partial Refund

You can refund a tax calculation request before requesting an authorization if you have access to the original transaction data. For example:
  1. Refund the full or partial amount of the original transaction.
  2. If the refund is successful, request the tax calculation service for the refunded item(s) and include the refund indicator by using the
    taxService_refundIndicator
    field set to
    true
    .
