title: How can I get Amplitude metrics for New Users via the API?
body: <p>For the Amplitude REST API, the 'event_type' for the system event '[Amplitude] Any Event' is '_active', as mentioned here:

  <p>I use this to get my active users like so:</p>
  
  <pre><code>curl -u KEY:SECRET 'https://amplitude.com/api/2/events/segmentation?e=\{"event_type":"_active"\}start=20170301&amp;end=20170321'
  </code></pre>
  
  <p>What is the 'event_type' for the system event '[Amplitude] New User'?</p>
