Fulfillment Order Notification - Cancellation Not Received

New Member
2 0 1

I'm new to the Fulfillment API and am coding the callback for the fulfillment_order_notification functionality. The FULFILLMENT_REQUEST call works fine, but I'm not receiving the CANCELLATION_REQUEST calls after I cancel fulfillment on test orders. My flow is to add an order, request fulfillment, verify that it's received on the call back (which it is) and then cancel fulfillment. I've logged everything arriving on the call back and so far, none of the cancellation requests are getting there. I'm sure I'm missing something obvious. Any ideas?

I'm getting the same problem. Were you able to find out why this is happening?
