I need to find products in certain domains - Art, Vintage, Antique, and a couple of others. None of these are listed here:
http://developer.ebay.com/devzone/shopping/docs/callref/ProductDomains.html#US The API docs suggest sort of a reverse engineering the domains from products. But... I can't get any products in my desired domains by doing the API search, because without a domain name it brings back products from "books" which I guess is the default. And I can't get the Reference ID of a products from the actual product page, because it's not listed there. So basically there's no solution. And the page to open a support ticket appears to be broken and not working.
https://go.developer.ebay.com/ How does anyone have any luck implementing this API is beyond me.
