Subscribing

Add shipment.rebill.dispute.created to a configuration's subscribedEvents with Create a webhook configuration or in the dashboard. The token needs permission to read rebills. Without it, the request answers 403 MISSING_PERMISSION, and opening or resending these deliveries in the dashboard is refused too. Such a token can still remove the event from a configuration.
