Answer 1

Use this one it's working for me

# Includes the autoloader for libraries installed with composer
require __DIR__ . '/vendor/autoload.php';

putenv('GOOGLE_APPLICATION_CREDENTIALS=../service-account.json');
$client = new Google_Client();
$client->useApplicationDefaultCredentials();
$client->setScopes(['https://www.googleapis.com/auth/analytics.readonly']);
$client->refreshTokenWithAssertion();
$token = $client->getAccessToken();
$accessToken = $token['access_token'];
