What are the advantages of using PHP SDKs provided by PayPal for integration compared to custom scripts?

When integrating PayPal into a website or application, using PHP SDKs provided by PayPal offers several advantages over custom scripts. SDKs handle the complexities of the PayPal API, provide built-in error handling, offer support for various payment methods, and ensure compatibility with future updates from PayPal. This can save time and effort in development and maintenance.

// Example code using PayPal PHP SDK
require 'vendor/autoload.php';

use PayPal\Rest\ApiContext;
use PayPal\Auth\OAuthTokenCredential;

$apiContext = new ApiContext(
    new OAuthTokenCredential(
        'CLIENT_ID',
        'CLIENT_SECRET'
    )
);

// Make API calls using $apiContext
