What best practices should be followed when using PHP to interact with the Google Analytics API?

When using PHP to interact with the Google Analytics API, it is important to follow best practices to ensure secure and efficient communication. This includes properly authenticating your requests using OAuth 2.0, handling errors gracefully, and optimizing your code for performance.

// Include the Google API PHP client library
require_once 'vendor/autoload.php';

// Set up the client with your credentials
$client = new Google_Client();
$client->setAuthConfig('client_secret.json');
$client->setAccessType('offline');
$client->setApprovalPrompt('force');
$client->setScopes(['https://www.googleapis.com/auth/analytics.readonly']);

// Authenticate with the client
$client->fetchAccessTokenWithAuthCode($_GET['code']);

// Make a request to the Google Analytics API
$analytics = new Google_Service_Analytics($client);
$profile = $analytics->management_profiles->listManagementProfiles('123456789', 'UA-12345678-1');
print_r($profile);
