Google Groups Directory API - Add user to group - PHP Function - php

Question

How do I use this function?
I have a userid and a group id.
The error message I get when I try to add my fields has to do with the Google_Member instance. How would I use this in my PHP code?
BTW it is from the Google Apps API
/**
* Add user to the specified group. (members.insert)
*
* #param string $groupKey Email or immutable Id of the group
* #param Google_Member $postBody
* #param array $optParams Optional parameters.
* #return Google_Member
*/
public function insert($groupKey, Google_Member $postBody, $optParams = array()) {
$params = array('groupKey' => $groupKey, 'postBody' => $postBody);
$params = array_merge($params, $optParams);
$data = $this->__call('insert', array($params));
if ($this->useObjects()) {
return new Google_Member($data);
} else {
return $data;
}
}

Follow the instructions listed here to setup the application in Google Console and to enable Domain Delegation of Authority.

Download the client from: https://code.google.com/p/google-api-php-client/downloads/list
Here is my working code:
require_once "google-api-php-client/src/Google_Client.php";
require_once "google-api-php-client/src/contrib/Google_DirectoryService.php";
require_once "google-api-php-client/src/contrib/Google_Oauth2Service.php";
session_start();
const GROUP_SCOPE = 'https://www.googleapis.com/auth/admin.directory.group';
const SERVICE_ACCOUNT_EMAIL = '.....#developer.gserviceaccount.com';
const SERVICE_ACCOUNT_PKCS12_FILE_PATH = '/path/to/...privatekey.p12';
const CLIENT_ID = '....apps.googleusercontent.com';
$userEmail = 'email-address-with-admin-rights#domain.com';
$key = file_get_contents(SERVICE_ACCOUNT_PKCS12_FILE_PATH);
$auth = new Google_AssertionCredentials(SERVICE_ACCOUNT_EMAIL, array(GROUP_SCOPE), $key, 'notasecret', 'http://oauth.net/grant_type/jwt/1.0/bearer', $userEmail);
$client = new Google_Client();
$client->setClientId(CLIENT_ID); // from API console
$client->setApplicationName("Project Name from API Console");
$client->setUseObjects(true);
$client->setAssertionCredentials($auth);
$member = new Google_Member(array('email' => 'abc#testing.com',
'kind' => 'admin#directory#member',
'role' => 'MEMBER',
'type' => 'USER'));
$service = new Google_DirectoryService($client);
$results = $service->members->insert('mailing-list-name#domain.com', $member);
print '<h2>Response Result:</h2><pre>' . print_r($results, true) . '</pre>';

$updateEmail = $_POST["email"];
//USING A SERVICE ACCOUNT TO CALL GOOGLE CLIENT
