title: What minimal permission a Global Admin user should have to retrieve data via CSOM API from site collection?
body: <p>I am trying to get some content from site collections in O365 via CSOM API.<br>
  I am using the <strong>Global Administrator</strong> account and getting the following error:     <em>Access denied. You do not have permission to perform this action or access this resource.</em>  </p>
  
  <p>If I give the Global Administrator user that I use the Site Collection Administrator permission, then I am not getting the exception.  </p>
  
  <p>Is it possible to give the Global Admin another <strong>less powerful then Site Collection Administrator</strong>  to achieve the same result?<br>
  If no, is there any other API that doesn't require adding the Site Collection Administrator permissions to the Global Administrator?</p>
