To service the subscription, you must be given some token? You should be able to hand that token to Apple and tell them to cancel the associated subscription.

Apple definitely provides you with unique details about the transaction and your system can verify whether renewal occurred or not. Wish they would add an API for cancelling. It would significantly reduce the number of rude emails we get from people if we could offer a cancel button in the app.

However, it would not solve the issue of people that think that simply deleting the app will cancel the subscription, or dissuade people from insisting that we cancel the subscription for them.

That sounds right but the problem is how to associate the user with the token beyond something in your app. I just am not sure how I would go from a twitter support account to canceling the subscription.

I don't know the details of the current API, but wouldn't you already need some basic information about your subscribers before that? To, you know, actually do the thing that the user subscribed to...

I read the docs, but I get the feeling we need someone to detail exactly what the store gives you for personal information. It seems like tokens but I'm probably missing something.
