        message: "Incorrect request"
      };

      try {
        res = JSON.parse(res);
        if (res.error) {
          e = {
            debug: res.error,
            message: res.error
          };
          res = null;
        }
      } catch (error) {
        e = error;
        e = {
          debug: "Couldn't JSON.parse response from the server: " + res,
          message: res

Vervolgens kan je het volgende doen:

var params = {
  sys_id: 'j40skldhG40dJ2i3jnn4',
  search: 'i can not find my printer settings',
  type: 'ticket'
}

            "Script-Include",  "functie" 'object met data', 'callback'
SN.get('ITGuardian',       'ticket',    params,               function(e, data) {});

Je krijgt dan in je callback een eventuele error terug of data.
