Scenario 2: Stand-alone Credit

You can credit a transaction if you do not have access to the original transaction data. For example:
  1. Request the tax service with the
    taxInformation.refundIndicator
     field set to
    true
    .
  2. Credit the payment.
NOTE
You can include the commit indicator by setting the
taxInformation.commitIndicator
 field to
true
 to indicate the credit was successfully processed in the Tax Detail Report. The commit indicator can also be sent during the first tax service request, such as Scenario 1, or in subsequent tax service requests, such as Scenario 2. If the credit fails, void the previously committed tax service request. See Void Tax Calculation.
