I want to a leaderboard to most users purchases but i dont know him id if user change own device .

Answer 1

The best you could do would be to have their app call StoreContext.GetUserCollectionsAsync from the UWP app on the user machine, then forward these results to your services. This isn't really all the purchase, but is all the things the user currently owns.

Or, using your UWP app again, just keep track of it immediately after the purchase succeeded. But I don't think there is any way to look up their purchase history directly.

A more complicated solution would be to use the B2B APIs. This would allow them to query the collections service directly from their service. This is probably the closest to what you are wanting. The token that get back would be unique to the user (not device).
