I am looking for the ad fee for a specific order. I see that the GetTransactions api gives you back ad fees but there is no way to safely associate that to a specific order. I thought it would be included marketplaceFees array but it is not. There is a separate entry for the ad fees with a transaction type of NON_SALE_CHARGE but it is hard to associate that with an order.
One way would be to get the first AD_FEE transaction after the payment transaction for the order, but can I be sure that it will be the correct fee ALWAYS?
