store API - supporting subscriptions

I understand from this thread: https://forums.coronalabs.com/topic/73972-ios-in-app-subscription-expire-date/page-2 that there is another version of iOS store API that can handle subscriptions. Can I get instructions on how to access it? I need to perform validation on subscriptions for our latest app.
