How to get the productId from an iOS consumable in-app purchase?

On my server, I am calling Apple's https://buy.itunes.apple.com/verifyReceipt endpoint which returns a json object with receipt data.

However, this object doesn't seem to have the productId of the purchased in-app purchase.

I need to know the productId so I actually know which IAP was bought...surely there is some sort of identifier for the actual product purchased?

Solution
