[AhmedRaza]

I want to try cancelling an order by using respective API's .

Customer have purchase two Line Items. But He want to cancel a one line Item. How can we do that.?

Can you help me which value are required to pass API's Call in Line Item cancellation. In Order cancellation case we pass a OrderID in respective API call. He work fine.
