Hi Tim.
At the moment, Subscription addon requires all hooks to be sent. Stripe is modifying its API, so over time we will narrow down the list of required events only to those that are actually required.
The best way to is to let the addon create webhooks automatically using this manual: https://s-plugins.com/stripe-subscription-payments-addon/#webhooks It will handle all the stuff for you automatically to make sure there are no issues.
