Refunds all the transactions of an account that have taken place since the most recent payout. This request is on a account basis (as opposed to a payment basis), so only the portion of the payment that was made to the specified account is refunded. The commissions, fees, and payments to other accounts remain in the accounts to which they were sent as designated by the original payment's split details.
