first of all I ask you for some flexibility, I have the ebay portal in Italian and I don't know if the translations of the menus are correct with the English counterpart.
From the portal, on the "sales rules manager" I have a shipping rule to which I would like to link my new items that I add to the catalog for sale (all with the "AddFixedPriceItem" function). But when I create the new listing it also generates a new shipping rule, which is correct except for the "Apply my rule for flat rate shipping" checkbox under "Discounts on combined shipping".
The software is developed with the SDK for .net, and to set the my shipping rules I use the "ShippingDetailsType" class.
Any suggestions ?
