You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: workhorse.rb
    path of file: ./repos/gitlabhq/lib/api/internal
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module API
  module Internal
    class Workhorse < ::API::Base
      feature_category :not_owned # rubocop:todo Gitlab/AvoidFeatureCategoryNotOwned

      before do
        verify_workhorse_api!
        content_type Gitlab::Workhorse::INTERNAL_API_CONTENT_TYPE
      end

      helpers do
        def request_authen
    
        def request_authenticated?
          authenticator = Gitlab::Auth::RequestAuthenticator.new(request)
          return true if authenticator.find_authenticated_requester([:api])

          # Look up user from warden, ignoring the absence of a CSRF token. For
          # web users the CSRF token can be in the POST form data but Workhorse
          # does not propagate the form data to us.
          !!request.env['warden']&.authenticate
        end
      end
