Refunds and voids

Refunds and voids are related to the process of reversing a purchase already confirmed or the cancellation of a pre-authorized purchase.

Before we start, let’s review some concepts.

Void: A void is the act of canceling a pre-authorized transaction (rollback) before it is finalized or settled. When a transaction is voided, it is as if the purchase never occurred, and no money is transferred. Voids usually occur before the payment is fully processed, so the customer’s payment method is not charged for the voided transaction.
Refund: A refund, on the other hand, is a transaction that occurs when a customer returns a purchased item or cancels a service, and the merchant reimburses the customer for the amount paid. The refunded amount is usually returned to the original payment method used by the customer. Unlike voids, the refund occurs after the transaction has been settled.

The rollback operation is only available for purchases previously authorized with state PreAuthorized.
