Grape

Starting from version 2.2 Doorkeeper provides helpers for the Grape framework >= 0.10. One of them is doorkeeper_authorize! that can be used in a similar way as an example above to protect your API with OAuth. Note that you have to use require 'doorkeeper/grape/helpers' and helpers Doorkeeper::Grape::Helpers in your Grape API class.

For more information about integration with Grape see the Wiki.

require 'doorkeeper/grape/helpers'
​
module API
  module V1
    class Users < Grape::API
      helpers Doorkeeper::Grape::Helpers
​
      before do
        doorkeeper_authorize!
      end
​
      # route_setting :scopes, ['user:email'] - for old versions of Grape
      get :emails, scopes: [:user, :write] do
        [{'email' => current_user.email}]
      end
​
      # ...
    end
  end
