CheckVoid is used to cancel a previously successful CheckSale transaction. It can also be used to cancel a prior CheckSale transaction. This should be used in timeout situations or when a complete response is not received.
Note:CheckVoid transactions should be submitted within 31 days of the original transaction.
Note:If the CheckVoid also fails to return a complete response (likely due to a timeout), wait until connectivity is restored and try again or contact support to ensure the proper result was achieved. CheckQuery can be used to check the status of a prior CheckSale transaction.
