I am using Yii and the google API for yii from here yii google api. I want to fetch the contact list with this api but this is throwing the error

                'grant_type'=>  urlencode('authorization_code')
            );
            $post = '';
            foreach($fields as $key=>$value)
            {
                $post .= $key.'='.$value.'&';

            $result = $this->curl('https://accounts.google.com/o/oauth2/token',$post);

maybe this link helps you. This person made an effort to get solutions for issues common like yours. http://stackoverflow.com/questions/33754177/google-analytics-custom-plugin-getting-error-invalid-grant — izk, Mar 04 '16 at 10:52
The Code was already redeemed error means that you are trying to use an authorization code that has already been used. A given authorization code can only be used once. Please make sure you are using the authorization code passed in the request to the oauth2_callback when you submit the OAuth request to get the refresh token. — RK12, Mar 04 '16 at 10:57

I have solved this . I just need to use function to get access token by function $client->getAccessToken().

public function actionIndex()
    {
        $client = Yii::app()->GoogleApis->client;
        $client -> setAccessType('online');
        $client -> setScopes('https://www.google.com/m8/feeds');
        $client->authenticate();

        if (isset($_GET['code'])) {

            $accesstoken=json_decode($client->getAccessToken());
            $accesstoken=$accesstoken->access_token;
            Yii::app()->session['accesstoken']=$accesstoken;
            $this->redirect(array('/'));
        }
        $this->render('index');
    }

Nicely done. I only provided a Link so did not do much. Happy you solved it! — izk, Mar 04 '16 at 13:30
but that helped me to find that no need to fetch access token again . thanks again :) — Manoj Dhiman, Mar 04 '16 at 13:31
