VoidTransaction Method

Voids a previous transaction.

Syntax

public void VoidTransaction();
Public Sub VoidTransaction()

Remarks

This method is used to void a transaction previously made with the RedeemCard, LoadCard, or ActivateCard methods. The VoidType property indicates the type of transaction you wish to void. Voiding a redemption adds the TransactionAmount back onto the gift card. Voiding a Load removes the TransactionAmount from the card. Voiding an Activation removes the TransactionAmount from the card and resets the state of the card to unactivated. However, Activations can only be voided if any subsequent transactions after the initial activation are voided first. See the VoidType property for more information.

The Response Code and Text fields indicate whether this transaction was successful.

Important Note: You must ping your list of service provider URLs and update the URL property to the service provider with the shortest response time every 100 transactions, as well as when your application initially starts. This is not a normal ICMP ping - to determine the fastest transaction URL you must use the special Ping method inside the FDMSRegister component. (You may update your list of service provider URLs with the FDMSRegister component's ServiceDiscovery method).

.NET Standard Notes

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