we are having issue with ebay api. We are try to integrating ebay api with our website <Removed>
1) seller will download their active orders to our website.
2) once order are downloaded they will calculate the shipping using our website courier services for the order which are still not paid.
3) once shipping cost calculated the shipping cost for the selected item will be uploaded automatically to the item so buyer can see the cost of postage and place the order.
we can able to complete the point 1 & 2 but point 3 is important for us. we can not able to find the correct xml request to update the shipping cost for the order. please help us to find that.
