Webhooks
In order to display a list of your customer's invoices, you must configure the appropriate webhooks on Stripe or Braintree.
Stripe webhooks should be configured to point to the /webhook/stripe URI. The Braintree subscription_canceled, subscription_charged_successfully, and subscription_expired webhook events should be configured to point to /webhook/braintree URI.
Another question. Does that mean that Spark only handles these 3 webhooks (subscription_canceled, subscription_charged_successfully, and subscription_expired) or does it handle other Braintree webhooks like Charged Unsuccessfully, Went Past Due, etc??
