What best practices should PHP developers follow when working with external APIs like the Graph API for data analysis tasks?

When working with external APIs like the Graph API for data analysis tasks, PHP developers should follow best practices to ensure smooth integration and efficient data retrieval. Some key practices include handling errors gracefully, implementing proper authentication and authorization mechanisms, optimizing API calls to reduce latency, and securely storing API credentials.

// Example of making a request to the Graph API using cURL in PHP
$accessToken = 'YOUR_ACCESS_TOKEN';
$apiUrl = 'https://graph.facebook.com/v13.0/me?fields=id,name,email';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $apiUrl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Authorization: Bearer ' . $accessToken
));
$response = curl_exec($ch);
if($response === false){
    echo 'Error: ' . curl_error($ch);
} else {
    $data = json_decode($response, true);
    // Process the data as needed
}
curl_close($ch);
