title: Get list of custom dimensions names with GA API v3?
body: <p>How to <strong>get a list of custom dimensions</strong> from Google Analytics API (v3)?</p>
  
  <p>I have setup a custom dimension named "Foo" in analytics console.</p>
  
  <p>I have used GA <a href="https://developers.google.com/analytics/devguides/reporting/metadata/v3/reference/metadata/columns/list" rel="nofollow">Metadata API v3</a> to retrieve all the columns, but I just did not find any item amongst that holds "Foo" in any way.</p>
  
  <p>Did anybody retrieve such a <strong>custom dimension column names</strong> list ever?</p>
