Passing shipping option in xml rpc api

I am using xml-rpc api. I did not get any method of passing shipping option(shipping price) while creating order. Can anyone please help.

if you are using order API than use create an order item and set item shipping and price https://developer.infusionsoft.com/docs/rest/#!/E-Commerce/createOrderItemsOnOrderUsingPOST , if you are using XML invoice API use add order item method https://developer.infusionsoft.com/docs/xml-rpc/#invoice-add-an-item-to-an-invoice
