    ACTIONS = {
        :fax => :send,
        :mailing => :send,

    def initialize(access_token,app_id)
      @graph = Koala::Facebook::API.new(access_token)

    def can_send_action? action
    end

    def send_action(class_name,fb_url)
      fb_post ACTIONS[class_name.to_sym] , fb_url

      response = HTTParty.post("#{FB_URL}",:body => data)
      Rails.logger.debug("FB RESPONSE: #{response.inspect}")
