PHP Google Analytics API Authorization error - php

Question

I want to fetch Google Analytics data for my website via Google Analytics API.
First, I went to developers console, I enabled Analytics API, then under credentials section I created new ClientID (Service account).
Now, this is my code
include "assets/src/templates/base.php";
require_once 'assets/src/Google/autoload.php';
$client_id = 'xxx.apps.googleusercontent.com'; //Client ID
$service_account_name = 'yyy#developer.gserviceaccount.com'; //Email Address
$key_file_location = 'zzz/key.p12'; //key.p12
echo pageHeader("Service Account Access");
if (strpos($client_id, "googleusercontent") == false
|| !strlen($service_account_name)
|| !strlen($key_file_location)) {
echo missingServiceAccountDetailsWarning();
exit;
}
$client = new Google_Client();
$client->setApplicationName("app");
$service = new Google_Service_Analytics($client);
if (isset($_SESSION['service_token'])) {
$client->setAccessToken($_SESSION['service_token']);
}
$key = file_get_contents($key_file_location);
$cred = new Google_Auth_AssertionCredentials(
$service_account_name,
array('https://www.googleapis.com/auth/analytics.readonly'),
$key
);
$client->setAssertionCredentials($cred);
if ($client->getAuth()->isAccessTokenExpired()) {
$client->getAuth()->refreshTokenWithAssertion($cred);
}
$_SESSION['service_token'] = $client->getAccessToken();
$result = $service->data_ga->get(
'ga:AAA',
'2015-03-03',
'2015-03-03',
'ga:sessions');
?>
where AAA is my ViewID.
So, my problem is this: When I access this script on server it says
*"Fatal error: Uncaught exception 'Google_Service_Exception' with message 'Error calling GET
https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A91249839&start-date=2015-03-03&end-date=2015-03-03&metrics=ga%3Asessions:

Any suggestions?
Thank you in advance!

Edit: I've tried Google Books api and auth is working ok. (I've changed that link in $cred ofcourse.

Answer 1

The key error is this:
(403) User does not have any Google Analytics account
You are logging in with a service account. You need to grant the service account access to your Google analytics account.
Solution:
Go to the google analytics website. On the admin section add a new user using the service account email address, at the ACCOUNT LEVEL it must be the ACCOUNT LEVEL give this new user read access only that's all it really needs.
Then try your script again.
