Cancel can only be used on ACH credit payments associated with funded payrolls whose payment attempt has not yet been transmitted to the payment processor. These payments have a 'draft' or 'processing' status — a payment reads 'processing' from the moment it is created with the processor, which is before it is transmitted — so use the can_cancel boolean rather than the status to determine whether a payment can be canceled.

Cancel must be used prior to the payment's fulfillment being sent out. This is denoted by the cancel_deadline field and is generally around 1 pm ET the day before the payday of the credit's associated payroll.

Canceled payments have a status of failed.
