title: can I access the unique client Id through GA API?
body: <p>I am currently querying my Google Analytics data using the <a href="https://developers.google.com/analytics/devguides/reporting/" rel="nofollow noreferrer">Google Analytics API</a> via R. </p>
  
  <p>I would like to query based on the unique <a href="https://developers.google.com/analytics/devguides/collection/protocol/v1/parameters#cid" rel="nofollow noreferrer">client ID</a> as my primary dimension, but I can't find this dimension using the API.</p>
