I thought that user/getSalesData would do this. Querying for "type=subscriptions" (2.) I indeed get the correct result, but I can't seem to get correct values for the paid type (1.). The type parameter can be "all", "standard", "extended" and "subscription". Even if I query for "all" and then subtract the "subscriptions" (so in order to get everything minus subscriptions or "standard" + "extended") The resulting number is way too small.
Also using user/getUserStats the total result for "nb_media_sold" doesn't seem to correlate with the sales data that I get form the API.
Can anybody help me understand these numbers?
