The PaymentExpress back-office application allows users to
initiate voids and refunds of card transactions. A void is a
same-day reversal that stops money from moving. A refund is an
after-same-day reversal that returns money to the cardholder.
Your system of record can use the Reversals will to initiate
voids and refunds in real-time using the paymentId of the
transaction. Any void or refund actions will be reflected in the
your elected Post-Payment Operations.
