 StripeEvent is built on the [ActiveSupport::Notifications API](http://api.rubyonrails.org/classes/ActiveSupport/Notifications.html). Incoming webhook requests are [authenticated with the webhook signature](#authenticating-webhooks-with-signatures). Define subscribers to handle specific event types. Subscribers can be a block or an object that responds to `#call`.
