title: Connecting to Google Analytics API in a Rails app
body: <p>Is there a good tutorial available re: how to interact with the Google Analytics API within a Rails app? I've found <a href="https://gist.github.com/joost/5344705" rel="nofollow">this gist</a>, but I'm not sure if every step listed in that gist is necessary.</p>
  
  <p>If that is a good tutorial to follow, where can I download the "key_file" that's mentioned? I can't seem to find it within <a href="https://code.google.com/apis/console/" rel="nofollow">https://code.google.com/apis/console/</a>. Also, where do I find out my API client email address / SERVICE ACCOUNT EMAIL?</p>
