I am using the findItemsAdvanced API of the eBay Finding API. The call is working fine but I need it to return item specifics, you know the details that you see at the top of an eBay, such as :
EAN, MPN, ISBN, Manufacturer etc. I am specifically interested in getting the
I by default the item attributes fields where these items are stored aren't returned. The documentation seems ambiguous (to me) about this particular field stating that it is not controlled by the output selector.

findItemsAdvanced does not return the item specifics. You can instead use the itemID that is returned in the search results and use this to make a separate call to GetSingleItem in the Shopping service. This call will return the item specifics as long as you pass ItemSpecifics in the IncludeSelector field.
