How to get total shipping cost for an order ebay getOrders API

Question

I'm trying to get the total shipping cost for an order via the eBay GetOrders call in the API. I have created a test order that has 1 item with free postage, one item with a calculated shipping cost, and one item with a flat shipping cost (to cover all scenario's).

I've tried getting the shipping cost for each item using TransactionArray/Transaction/ActualShippingCost and then adding the total. Ive also tried ShippingDetails/ShippingServiceOptions/ShippingServiceCost but I can't seem to figure it out.

Here is the latest code I could come up with but it keeps reporting the error: "Object reference not set to an instance of an object"

double ShippingCost = 0.00;
foreach (TransactionType transaction in orderTrans)
{

    ShippingCost += transaction.ActualShippingCost.Value; //this line causes error
}
MessageBox.Show("Total Shipping Cost is: " + ShippingCost.ToString());

Answer 1

Try reading shipping cost from order:

if (order.ShippingServiceSelected.ShippingServiceCost != null)
{
    ShippingCost = order.ShippingServiceSelected.ShippingServiceCost.Value
}

we use this method in our code and it works.
