title: Use "default channel grouping" as a dimension in Google Analytics API
body: <p>I would like to use the Google Analytics API to get the data displayed on the Acquisition Overview webpage. Especially, I need to get the sessions (formerly called visits) break by Default channel grouping : Direct, Organic Search, Referral, Social, Paid Search, Email, Display and (Other).</p>
  
  <p>As explained <a href="http://www.seerinteractive.com/blog/new-google-analytics-channel-groupings#definitionofchannels" rel="noreferrer">here</a>, these groups are based on regex. Therefore, it might be possible to recode these rules, but I would prefer to use these groups as a dimension.</p>
  
  <p>I googled it and most of the answers are referring to Multi-Channel Funnels (MCF), but according to the <a href="https://developers.google.com/analytics/devguides/reporting/mcf/dimsmets/" rel="noreferrer">MCF dimensions &amp; metrics reference</a>, it's more about conversion. </p>
  
  <p>Does anyone know how to use the Google Analytics API (or GA MCF API) to get such data ?</p>
  
  <p>Thanks a lot !</p>
