Instance Method Details

#acknowledge ⇒ Object

We don’t actually acknowledge the notification by making another request ourself, instead, we check the notification by checking the signature that came with the notification. This method has to be called when handling the notification & deciding whether to process the order. Example:

def notify
  notify = Notification.new(params)

  if notify.acknowledge
    ... process order ... if notify.complete?
  else
    ... log possible hacking attempt ...
  end

end
