I have been updating all my old finding api scripts to the browse api. Everything (finally) seems to be working pretty well.
Until I got to a site about motors... I can access the US items by using the globalid EBAY_MOTORS (not EBAY_MOTORS_US as it seems to suggest in places).
My problem is accessing motors from other sites. As far as I can see I should use EBAY_GB as the globalid for the UK, but when I do I get the error 'category_ids' query parameter is invalidThe category number is fine as far as I can tell, and the error goes away if I use any other non-motors categories. Anybody got any suggestions? Thanks!
