ACH is the main network for the transfer of electronic funds within the US. Using ACH, both credits and debits are available, but ACH is typically slower than other payment transfer types (Wire, RTP, etc.). For more information on ACH, cutoff times, and transaction states, see ACH Payments.

This endpoint provides the ability to update an ACH transaction that has been submitted to Victor. Only transactions that are in a Pending state may be updated.
