Account transfers are instant therefore they cannot be canceled, however, if you created a payment and haven’t paid by fulfilling the Interac e-Transfer yet, you can let it expire which will result in the transaction being ‘Declined’. For Cash Pickups, if you have already fulfilled the Interac e-Transfer request – you can cancel the transaction until the status shows ‘Ready For Pickup’ which means the Contact has not yet collected the funds from NBP.
