Void Membership Charge

Voids a membership charge, returning the redeemed balance to the membership.

Wix calls this method to reverse a charge, for example when an order is canceled or refunded, after Get Membership Voidability has reported the charge as voidable.

Your implementation should: Reverse the charge identified by transactionId and restore the balance it consumed. Treat a repeat request for a charge you've already voided as TRANSACTION_ALREADY_VOIDED rather than restoring the balance a second time.

Error handling: Report an unrecognized transactionId as TRANSACTION_NOT_FOUND, a charge that can no longer be reversed as TRANSACTION_CANNOT_BE_VOIDED, and one already reversed as TRANSACTION_ALREADY_VOIDED.
