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.
