I am using Google Analytics. I am currently tracking page view and events on my app, and it works fine. I recently started working on tracking e-commerce data via the transaction event. It partially works.
I see the transactions and revenues coming through, but I am missing: Quantity, Product, Product Sku, and Product Category.
Here are a few sample urls:
http://www.google-analytics.com/collect ... 847&iv=Buyhttp://www.google-analytics.com/collect ... 835&iv=Buyhttp://www.google-analytics.com/collect ... 847&iv=Buyhttp://www.google-analytics.com/collect ... 863&iv=BuyOutside of changing my tid, and cid everything else is verbatim. As you can see item name(in), quantity(iq), category(iv) and sku(ic) have values in all three examples.
