to change it to your!
$iMaxResults = 20; // max results
$sStep = 'auth'; // current step

/system/plugins/GmailContacts/GmailOath.php?r=11
include_once('GmailOath.php');
session_start();
// prepare new instances of GmailOath and GmailGetContacts
$oAuth = new GmailOath($sClientId, $sClientSecret, $argarray, false, $sCallback);
$oGetContacts = new GmailGetContacts();
if ($_GET && $_GET['oauth_token']) {
$sStep = 'fetch_contacts'; // fetch contacts step
// decode request token and secret
$sDecodedToken = $oAuth->rfc3986_decode($_GET['oauth_token']);
$sDecodedTokenSecret = $oAuth->rfc3986_decode($_SESSION['oauth_token_secret']);
// get 'oauth_verifier'
$oAuthVerifier = $oAuth->rfc3986_decode($_GET['oauth_verifier']);
// prepare access token, decode it, and obtain contact list
$oAccessToken = $oGetContacts->get_access_token($oAuth, $sDecodedToken,
$sDecodedTokenSecret, $oAuthVerifier, false, true, true);
$sAccessToken = $oAuth->rfc3986_decode($oAccessToken['oauth_token']);

There are several ways to make access token request, and they vary based on the type of application you are building.
For example, a JavaScript application might request an access token using a browser redirect to Google, while an application installed on a device that has no browser uses web service requests.
Some requests require an authentication step where the user logs in with their Google account. After logging in, the user is asked whether they are willing to grant the permissions that your application is requesting. This process is called user consent.
If the user grants the permission, the Google Authorization Server sends your application an access token (or an authorization code that your application can use to obtain an access token). If the user does not grant the permission, the server returns an error.
Here is link for oauth play ground which helps to understand the concepts of Oauth .
