Haycamp is a sample Ruby on Rails app using the Chargify API. You can view the live demo here: http://haycamp.heroku.com

cp config/database.yml.sample config/database.yml
rake db:create:all
rake db:migrate

Add your subdomain and api key credentials to chargify.rb. For use with heroku you can set ENV variables as such http://docs.heroku.com/config-vars.

Chargify.configure do |c|
  c.subdomain = ENV['CHARGIFY_SUBDOMAIN']
  c.api_key   = ENV['CHARGIFY_API_KEY']
end

Add a few products to your chargify test account. Similar setup can be seen in the demo video.
