This is the OmniAuth OAuth2 strategy for authentication to FreshBooks.

Add this line to your application's Gemfile:

gem 'omniauth-freshbooks-oauth2'

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

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :freshbooks, ENV['FRESHBOOKS_KEY'], ENV['FRESHBOOKS_SECRET'] 
end
