title: How to get the start date in analytics reporting api?
body: <p>I am currently using Google Analytics Reporting API in my application. It has only one method, which is accessible on the next url - <a href="https://analyticsreporting.googleapis.com/v4/reports:batchGet" rel="nofollow noreferrer">https://analyticsreporting.googleapis.com/v4/reports:batchGet</a>.
  Using this method, I should specify the time range to get data from that period. </p>
  
  <p>Example of request body:</p>
  
  <pre><code>{
  "reportRequests": [
      {
          "metrics": [
              {
                  "expression": "ga:users"
              }
          ]
          "dateRanges": [
              {
                  "startDate": "2017-01-01",
                  "endDate": "2017-12-01"
              }
          ],
          "viewId": "1111111"
      }
  ]
  }
  </code></pre>
  
  <p>Is there any way to know the date when analytics started? Any suggestions?</p>
