How to prefill API key for swagger UI

I’m using:

• Rails 4.2.6
• Grape, Win Bouncer, Doorkeeper

How can I pre-fill API key for logged in user for swagger UI? The only way I figured out how to get the current token is by creating on separate rails app as an OauthClient. However, for convenience and in production I would like to prefill the api key in swagger UI. Or how can a logged in user get the api key easily?

wine_bouncer.rb:

WineBouncer.configure do |config|
  config.auth_strategy = :swagger

  config.define_resource_owner do
    User.find(doorkeeper_access_token.resource_owner_id) if doorkeeper_access_token
  end
end

swagger.rb:

GrapeSwaggerRails.options.url      = '/api/mobile/swagger_doc.json'
GrapeSwaggerRails.options.app_url  = 'https://www.domain.com'
GrapeSwaggerRails.options.api_key_name = 'access_token'
GrapeSwaggerRails.options.api_key_type = 'query'
