title: How do I find the immutable id of my Google Apps account?
body: <p>Many of the Directory API calls require a <strong>customer</strong> parameter referred to as the "Immutable id of the Google Apps account. (string)".</p>
  
  <p>e.g. GET <a href="https://www.googleapis.com/admin/directory/v1/customer/">https://www.googleapis.com/admin/directory/v1/customer/</a><strong><em>customer</em></strong>/domains</p>
  
  <p>I have no idea how to find/generate this for my Google Apps account. I am an admin.</p>
  
  <p>Can someone point me in the right direction please?</p>
