title: What is a viewId in Google Analytics?
body: <p>According to the Google Analytics "<a href="https://developers.google.com/analytics/devguides/reporting/core/v4/basics" rel="noreferrer">Creating a Report</a>" guide, a required field for a request is the viewId:</p>
  
  <blockquote>
    <p>A valid view ID for the viewId field.</p>
  </blockquote>
  
  <p>Cool. So what is a viewId and where do I find it? I click on the <a href="https://developers.google.com/analytics/devguides/reporting/core/v4/rest/v4/reports/batchGet#reportrequest" rel="noreferrer">viewId</a> link and it says:</p>
  
  <blockquote>
    <p>Unique View Id for retrieving Analytics data.</p>
  </blockquote>
  
  <p>Umm. Ok. But what <em>is</em> it, and how do I find it for the report I want? It doesn't appear to be the same as "property ID". Come on Google, we need a little more to work with here.</p>
