title: Policy API support
body: <p>Are there any box-api's for applying policies on any of the activity? For eg., collaboration/sharing restriction per user basis, or file type upload restriction per user or organization level.</p>
  
  <p>We have an enterprise account, we want to enable such policies. As an admin, I was wondering what are the APIs available for me.</p>
  
  <p>Thanks in Advance
