Helpdesk Bundle Laravel Package

Getting Started

Minimal Steps

1. Installation:

   composer require banckle/helpdesk-sdk-php banckle/helpdesk-bundle
   

   Update AppKernel.php to register the bundle:

   new Banckle\Bundle\HelpdeskBundle\BanckleHelpdeskBundle(),
   

2. Configuration: Add to config.yml:

   banckle_helpdesk:
       apiKey: "YOUR_API_KEY"
       banckleAccountUri: "https://apps.banckle.com/api/v2"
       banckleHelpdeskUri: "https://helpdesk.banckle.com/public/api/v1"
   

3. First Use Case: Inject the service in a controller/service and fetch contacts:

   use Symfony\Component\DependencyInjection\ContainerInterface;
   
   class ContactController {
       protected $container;
   
       public function __construct(ContainerInterface $container) {
           $this->container = $container;
       }
   
       public function indexAction() {
           $helpdesk = $this->container->get('bancklehelpdesk.api');
           $contacts = $helpdesk->getContacts(); // Hypothetical method (adjust based on actual SDK)
           return $this->render('contacts/index.html.twig', ['contacts' => $contacts]);
       }
   }
   

Implementation Patterns

Common Workflows

1. Authentication: Generate tokens for API access:

   $token = $this->get('bancklehelpdesk.api')->getToken('user@example.com', 'password');
   

2. CRUD Operations: Use the service for ticket/contact management:

   // Create a ticket
   $ticket = $this->get('bancklehelpdesk.api')->createTicket($data);
   
   // Fetch a ticket
   $ticket = $this->get('bancklehelpdesk.api')->getTicket($ticketId);
   

3. Event-Driven Integrations: Listen for Banckle Helpdesk webhooks (e.g., new tickets) via Symfony’s event system:

   # config.yml
   banckle_helpdesk:
       webhook:
           enabled: true
           secret: "YOUR_WEBHOOK_SECRET"
           endpoint: "/api/webhook/banckle"
   

   Register a listener:

   // src/Banckle/WebhookListener.php
   class WebhookListener {
       public function onBanckleWebhook(Request $request) {
           $data = json_decode($request->getContent(), true);
           // Process webhook data (e.g., create a local ticket)
       }
   }
   

4. Dependency Injection: Prefer constructor injection for testability:

   class TicketService {
       private $helpdesk;
   
       public function __construct(BanckleHelpdeskApi $helpdesk) {
           $this->helpdesk = $helpdesk;
       }
   }
   

5. Batch Processing: Use pagination for large datasets:

   $contacts = [];
   $page = 1;
   do {
       $pageContacts = $this->get('bancklehelpdesk.api')->getContacts($page);
       $contacts = array_merge($contacts, $pageContacts);
       $page++;
   } while (count($pageContacts) > 0);
   

Gotchas and Tips

Pitfalls

1. API Key Exposure:

   • Never hardcode apiKey in version-controlled files (e.g., config.yml). Use environment variables or Symfony’s parameter bag:

     # config.yml
     parameters:
         banckle.api_key: "%env(BANCKLE_API_KEY)%"
     banckle_helpdesk:
         apiKey: "%banckle.api_key%"
     

   • Restrict file permissions (chmod 600 config.yml).

2. Rate Limiting:

   • Banckle’s API may throttle requests. Implement exponential backoff in custom services:

     try {
         $response = $helpdesk->getTickets();
     } catch (RateLimitException $e) {
         sleep($e->getRetryAfter());
         retry();
     }
     

3. Deprecated Methods:

   • The SDK is in dev-master. Assume breaking changes in minor updates. Pin versions in composer.json:

     "banckle/helpdesk-sdk-php": "1.0.0",
     "banckle/helpdesk-bundle": "1.0.0"
     

4. Webhook Verification:

   • Validate webhook payloads to prevent spoofing:

     public function verifyWebhook(Request $request, string $secret) {
         $payload = $request->getContent();
         $expectedSignature = hash_hmac('sha256', $payload, $secret);
         if (!hash_equals($request->headers->get('X-Banckle-Signature'), $expectedSignature)) {
             throw new \RuntimeException('Invalid webhook signature');
         }
     }
     

Debugging Tips

1. Enable API Logging: Configure Monolog to log Banckle API requests/responses:

   # config.yml
   banckle_helpdesk:
       debug: true
   

   Add a Monolog handler for the banckle channel.

2. Mocking the SDK: For testing, mock the BanckleHelpdeskApi service:

   $mock = $this->createMock(BanckleHelpdeskApi::class);
   $mock->method('getContacts')->willReturn([/* mock data */]);
   $container->set('bancklehelpdesk.api', $mock);
   

3. Common Errors:

   • 401 Unauthorized: Verify apiKey and account URI.
   • 404 Not Found: Check if the Helpdesk URI is correct (e.g., v1 vs. v2).
   • 500 Server Error: Contact Banckle support with the exact request payload.

Extension Points

1. Custom API Clients: Extend the bundle’s service to add domain-specific methods:

   // src/Banckle/CustomHelpdesk.php
   class CustomHelpdesk extends BanckleHelpdeskApi {
       public function getSupportTicketsForUser(string $userId) {
           return $this->get('/tickets', [
               'filter' => ['user_id' => $userId]
           ]);
       }
   }
   

   Override the service in services.yml:

   services:
       bancklehelpdesk.api:
           class: App\Banckle\CustomHelpdesk
           arguments: ['%banckle_helpdesk.api_key%']
   

2. Event Dispatching: Trigger Symfony events for Banckle actions (e.g., ticket.created):

   $dispatcher->dispatch(new TicketEvent($ticket), 'banckle.ticket.created');
   

   Listen globally in EventListener/TicketListener.php.

3. Data Transformers: Use Symfony’s serializer to normalize Banckle responses:

   $serializer = $container->get('serializer');
   $normalized = $serializer->normalize($contacts, 'array');
