How to use a webhook to trigger subscription data refresh

gistfile1.rb

 
EVENTS_THAT_INCLUDE_SUBSCRIPTION_INFORMATION = ["payment_success", "billing_date_change"]
 
def handle_event
  event = params["event"]
  payload = params["payload"]
  return head(:unprocessable_entity) unless if event.blank? || payload.blank?
  return head(:ok) unless EVENTS_ABOUT_WHICH_WE_CARE.include?(event)
  
  subscription_id = payload["subscription"]["id"]
  user = User.find_by_subscription_id(subscription_id)
  
  # normally I'd suggest putting this in the user model, but it is included here for simplicity
  subscription = Chargify::Subscription.find(self.subscription_id) # assuming you've already set things up using activeresource
  user.active = subscription.state == "active" # for example, your user model may vary
  # ... and so on
end
