APPROVEREVERSAL

An ApproveReversal command modifies the approved amount of a payment. For example, if a payment enters the ApprovalExpired state, then you can use the ApproveReversal command either to get a new approval or to void the payment. ApproveReversal is valid for payments in the Approved state. If the ApproveReversal is successful, and the amount specified is "0," then the payment moves to Void state. If the amount specified is not "0," then the payment stays in Approved state and the approved amount is modified.
