This is the OmniAuth strategy for authentication to Hootsuite.

Add this line to your application's Gemfile:

gem 'omniauth-hootsuite'

And then, you need to add the following to your config/initializers/omniauth.rb:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :hootsuite, "consumer_key", "consumer_secret"
end

You will obviously have to put in your key and secret, which you get when you register with Hootsuite.
