Transactions

Cancel a bank transfer

Changed on

Request cancellation of a pending bank transfer — an ACH transfer (push or pull) or a wire — before it has settled, for example a payment or collection initiated outside of the receiving bank's processing window. Whether a transfer can still be cancelled is determined by the banking partner that is settling it: the request is forwarded to the partner's own cancellation facility, and a transfer that the partner has already processed (or that is otherwise past its cancellation window) cannot be cancelled. Cancellation applies to bank-rail transfers; requests for transaction types that cannot be cancelled are rejected.
