VigLink

After you sign up, you'll see a snippet of code like this:

<script type="text/javascript">
  var vglnk = { api_url: '//api.viglink.com/api',
                key: 'ef9e930d0a57fddabc39ec15c05123ef' };

  (function(d, t) {
    var s = d.createElement(t); s.type = 'text/javascript'; s.async = true;
    s.src = ('https:' == document.location.protocol ? vglnk.api_url :
             '//cdn.viglink.com/api') + '/vglnk.js';
    var r = d.getElementsByTagName(t)[0]; r.parentNode.insertBefore(s, r);
  }(document, 'script'));
</script>

The code needs to be present on every page where you'd like VigLink to work. The best way to install this code everywhere is to add it to your site's template.
