title: Facebook Messenger: How to access "last active" time of friends?
body: <p>I'm trying to build an app that displays the information when a particular friend was last active simply by pulling it from your messenger app if an fb api access token has been granted. </p>
  
  <p>But..does anyone know how to get this information because unless I missed it, facebook doesn't have a specific API call for it. Any recommendations on how I might go about pulling this data in a custom way? I know that anyone logged into the messenger app on either mobile and/or messenger.com has access to this data for their friend's list. </p>
  
  <p>Thanks in advance for any advice. </p>
