Voiding Merchant Account Service credit card payments
Credit card transactions that have been authorized using Merchant Account Service can be voided within a certain period. You may need to void a payment if a customer no longer wants to purchase the product and you have already authorized the payment.
You will know if a transaction has been authorized when an Authorization Code and Trace ID appear in the Applied Payment Details window. You’ll also see that the Authorize button has been changed to a Void Authorization button. If you try to void an authorized transaction after the set period, the void transaction will be declined and you will have to process a credit transaction.
