What considerations should be taken into account when integrating a custom plugin on external websites that interacts with a Facebook app?

When integrating a custom plugin on external websites that interacts with a Facebook app, it is important to consider the security implications and ensure that proper authentication and authorization mechanisms are in place. Additionally, it is crucial to adhere to Facebook's platform policies and guidelines to avoid any potential issues or violations. 

// Example PHP code snippet for integrating a custom plugin with a Facebook app

// Include the Facebook PHP SDK
require_once 'facebook-php-sdk/autoload.php';

// Initialize the Facebook SDK with your app credentials
$fb = new Facebook\Facebook([
  'app_id' => 'your_app_id',
  'app_secret' => 'your_app_secret',
  'default_graph_version' => 'v10.0',
]);

// Use the SDK to make API calls to interact with the Facebook app
try {
  // Make API calls here
} catch(Facebook\Exceptions\FacebookResponseException $e) {
  // Handle API errors
} catch(Facebook\Exceptions\FacebookSDKException $e) {
  // Handle SDK errors
}
