Wesley van Wyk

The code returns the client ID of the first element in the ga.getAll() array.

function(){
  return ga.getAll()[0].get('clientId');
}

function() {
  try {
    var tracker = ga.getAll()[0];
    return tracker.get('clientId');
  } catch(e) {
    console.log("Error fetching clientId");
  }
}
