## What happens next

When you submit the reversal request, the system creates a reversal entry in **Payment History**. The system transmits the request to the receiving financial institution (RDFI) to debit or credit the receiver’s account, depending on whether the original transaction was a Push or Pull. The status of the payment changes to **Hold**.

When the reversal succeeds, the status of the payment changes to **Complete**.
