When you send a cancel order, you will see the status of the order change by way of receiving an "oc" message. You will also receive a notification that the order was requested to be canceled of the type "oc-req".

You can cancel the order by the Internal Order ID or using a Client Order ID (supplied by you). The Client Order ID is unique per day, so you also have to provide the date of the order as a date string in this format YYYY-MM-DD.
