Plan subscription auto renewal, how does it work?

@marlowe-shaeffer We need to interact with a non-Wix service after a subscription has been created and also after it auto renews.
It makes little sense to me that the wixPaidPlans interface provides only the event handling for the subscription creation and not the auto renewal. I’ve worked with Stripe and other payment processors and they have this functionality in their interfaces.
If there is no event handler for auto renewal, are their webhooks that can be used instead of events for both these cases (creation and autorenewal)?
