Laravel Cashier: Hooking into existing webhook

Hi all, With Cashier, it automatically cancels a user's subscription after 3 failed payment attempts. What I'm wondering is if there's a way to hook into not only Stripe canceling their subscription, but also if they cancel it from within my app to fire off an event that can be hooked into to do other items. My use-case is unpublishing records that are only published with an active subscription. Thanks!
