iOS In-App Purchase Refunds

[Ralph DiMola]

Does anyone know how to detect when a user that made a valid in-app purchase
and then subsequently asked for and received a refund from Apple? 
This is a in-app purchase for a subscription to intellectual property so I
need a way to know this so I can cut the user off. I have all the backend
server code to do this I just need to know if the user received a refund
from Apple.

Any ideas?
Thanks!
