Surcharge Fees

This feature enables you to charge the customer a surcharge fee for a PIN debit purchase or credit transaction.
IMPORTANT
Surcharge fees are not allowed on debit or prepaid cards in the U.S.
Include the surcharge amount in the total transaction amount, and set the
orderInformation.amountDetails.surcharge.amount
field to the surcharge amount. This information is passed to the issuer and acquirer for tracking. The issuer can provide information about the surcharge amount to the customer.
When there is no surcharge fee, do not include the
orderInformation.amountDetails.surcharge.amount
field in the request.
