I am calling PurchaseItem and am getting a generic ServiceUnavailable/BadRequest error. I tried passing in:
CatalogVersion (set to my catalog version), ItemId (set to a specific item id), VirtualCurrency (set to RM) and Price (set to 0)
I also tried creating a store and passing in the StoreId.
Does anyone know why this would fail? Is there any way to get a more detailed message?
