This gist shows a very simple way of fetching all admin users in your desk.com account and displaying it in a knowledge base article. IMPORTANT: this will only work if you're logged in as a desk.com agent and should never be a public article.

AdminReport.html

<style>
    table#users { width: 100%; }
    table#users th { font-weight: bold; font-size: 120%; }
</style>

<table class="table table-striped" id="users">
  <thead>
    <tr>
      <th>Name</th>
      <th>Email</th>
      <th>Level</th>
      <th>Last Login</th>
  </thead>
  <tbody>
  </tbody>
</table>

  (function($) {
    $el = $('#users tbody');
    
    function processUsers(users) {
      $.each(users._embedded.entries, function(idx, user) {
        if (!user.level.match('admin')) return;

        $([
          '<tr>',
          '  <td>' + user.name + '</td>',
          '  <td><a href="mailto:' + user.email + '">' + user.email + '</a></td>',

          '  <td>' + moment(user.last_login_at).format('lll') + '</td>',
          '</tr>'
        ].join("\n")).appendTo($el);
      });

      if (users._links.next) { $.getJSON(users._links.next.href, processUsers); }

    $.getJSON('/api/v2/users', processUsers);
