Checking if subscription is cancelled, but subscription period still active

[djendacott]

Is it possible to find out if a user has cancelled their subscription?

Eg, a user signs up for a 7 day trial, immediately cancels it, but is continuing to use the app for the remainder of the free trial period. In this case we'd like to offer the user a discount to resubscribe.

to identify if the user cancelled the subscription you have to

1. follow the apple guide to get notifications directly from the apple server
2. make a cron job in your server asking for validation of the lastest recipt

for discounts im not sure, but i think it is covered by the apple subscriptions documentation
