I've been trying to use findItemsAdvanced to get all of the vehicle listings in a given category (Make/Model). Here is a sample call:
http://svcs.ebay.com/services/search/FindingService/v1?OPERATION-NAME=fi...
That should return all of the items under Porsche, but there are only 1066 whereas on ebay.com there are 1,216. I've discovered the difference is with Classified Ads, which do NOT show up in my API call at all. I tried revising it to limit it to classified ads by adding:
itemFilter%280%29.name=ListingType&itemFilter%280%29.value=Classified
But that comes back with ZERO entries. Interestingly it returns:
<itemSearchURL>http://www.ebay.com/sch/6013/i.html?LH_CAds=1&_ddo=1&_ipg=100&_pgn=1</it...
Following that link indeed only shows Porsche classifieds listings, and with 150 of them! Why would the API return 0 results?
I'm pretty much at a loss. I don't want to do a query search since searching broadly I'll get more parts than vehicles, but I've been on this for a while now and can't find an answer. Can anyone please tell me how to get all listings in a given vehicle category, *including* Classified Ads, without a query term?
