Transactions eligible for settlement are automatically settled once every 24 hours. If the transaction you wish to void has already been settled, you cannot void the transaction. Instead, you must issue a refund transaction to send funds back to the customer's card or bank account. For instructions about issuing a refund transaction, please see the articles "How do I refund a credit card transaction?" and "How do I refund an eCheck.Net® transaction?" in the Related Items below this article.

If the transaction you wish to void has been approved and is pending settlement, the transaction can be voided.
