Void Last Purchase

Overview

The void last purchase command allows you to void the last completed transaction. You cannot use this command consecutively to void more than one transaction. In a partial approval transaction flow, the void last purchase will only void the last completed transaction. You must use the Void Purchase command to void all the remaining transactions.
