A Ruby Gem to simplify creation of PHG iTunes affiliate links
Add gem 'itunes-affiliate-link to your gemfile and run bundle install
Run bundle exec rails g itunes_affiliate:install.
This will create the file config/initializers/itunes_affiliate.rb - you should edit this and add
your affiliate token.
ItunesAffiliateLink.create_link(url, campaign_token)
The URL should be a standard iTunes link.
The campaign token is optional but can be used to identify the source of the affiliate commission.
