Implement payout reversal for an ACH credit that has already settled using Modern Treasury's ledger and reverse payment order flow

Steps

1. Identify the settled payment order that needs reversal and confirm the settlement date and effective date in Modern Treasury
2. Create a reversal object via the POST /payment_orders/{id}/reversals endpoint specifying the reason for the reversal
3. Modern Treasury will originate a return entry (CCD or PPD debit) against the settled credit; confirm the reversal object status transitions from pending to submitted
4. Monitor the reversal for its own return risk: the originating bank can reject the reversal if the account has since been closed or if the reversal window has passed
5. Update your internal ledger to reflect the reversed credit and reconcile against the Modern Treasury ledger transaction object
6. Notify the downstream recipient of the reversal and trigger any required customer communication
