Reverse Method

Reverses a transaction in the current batch.


public void Reverse(string PNRef);
Public Sub Reverse(ByVal PNRef As String)


A credit card Reversal transaction removes an unsettled, previously-submitted transaction. The PNRef parameter should be set to the PNRef from the transaction response of the transaction you wish to cancel.

A Reverse transaction differs from a VoidTransaction in one key way. A standard credit card sale puts a hold on the cardholder's open-to-buy funds until the batch is settled. If submitting a VoidTransaction, no money changes hands but a hold on the funds remains for a certain amount of time (usually around 7 days, depending on the issuing bank). A Reverse transaction releases the hold on the funds, and makes the funds available again immediately.

When two Reverse requests for the same transaction are submitted, a Reversal only occurs on the first transaction. If a Reversal request is submitted on a transaction which has already been reversed, Global Transport returns a "NO TRANS FOUND" message in the Response. Some standard card issuers may not support a Reversal. In this case, Global Transport returns a "DECLINE" response message. In this case, you should void it with the VoidTransaction method instead.

.NET Standard Notes

To call this method in an asynchronous manner call ReverseAsync instead. When the method completes (or an error is encountered) the ReverseCompleted event will fire.
