We think there are two solutions for you to solve this:
Solution 1: Create a new module
To achieve this, you will need to modify the code, which may be somewhat complex. You can try the following steps.
1. Create the module directory structure:
app/code/Webhook/Notification/
2. Create the `events.xml` file:
<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd"> <event name="sales_order_save_after"> <observer name="webhook_order_update" instance="Webhook\Notification\Observer\OrderUpdateObserver"/> </event> <event name="checkout_cart_product_add_after"> <observer name="webhook_cart_update" instance="Webhook\Notification\Observer\CartUpdateObserver"/> </event> </config>
3. Create the `WebhookService.php` file:
<?php
namespace Webhook\Notification\Model;
use Magento\Framework\HTTP\Client\Curl;
use Magento\Framework\Serialize\Serializer\Json;
use Magento\Store\Model\StoreManagerInterface;
use Magento\Framework\App\Config\ScopeConfigInterface;
class WebhookService
{
private $curl;
private $json;
private $storeManager;
private $scopeConfig;
public function __construct(
Curl $curl,
Json $json,
StoreManagerInterface $storeManager,
ScopeConfigInterface $scopeConfig
) {
$this->curl = $curl;
$this->json = $json;
$this->storeManager = $storeManager;
$this->scopeConfig = $scopeConfig;
}
public function sendWebhook($event, $data)
{
if (!$this->isEnabled()) {
return false;
}
$webhookUrl = $this->getWebhookUrl();
$secretKey = $this->getSecretKey();
$payload = [
'event' => $event,
'data' => $data,
'timestamp' => time()
];
$signature = hash_hmac('sha256', $this->json->serialize($payload), $secretKey);
$this->curl->addHeader('Content-Type', 'application/json');
$this->curl->addHeader('X-Webhook-Signature', $signature);
try {
$this->curl->post($webhookUrl, $this->json->serialize($payload));
return $this->curl->getStatus() === 200;
} catch (\Exception $e) {
return false;
}
}
private function isEnabled()
{
return $this->scopeConfig->isSetFlag('webhook/notification/enabled');
}
private function getWebhookUrl()
{
return $this->scopeConfig->getValue('webhook/notification/webhook_url');
}
private function getSecretKey()
{
return $this->scopeConfig->getValue('webhook/notification/secret_key');
}
}
4. Create the `OrderUpdateObserver.php` and `CartUpdateObserver.php` files in the `Observer` directory:
<?php
namespace Webhook\Notification\Observer;
use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;
use Webhook\Notification\Model\WebhookService;
class OrderUpdateObserver implements ObserverInterface
{
private $webhookService;
public function __construct(WebhookService $webhookService)
{
$this->webhookService = $webhookService;
}
public function execute(Observer $observer)
{
$order = $observer->getEvent()->getOrder();
$this->webhookService->sendWebhook('order_update', $order->getData());
}
}
<?php
namespace Webhook\Notification\Observer;
use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;
use Webhook\Notification\Model\WebhookService;
class CartUpdateObserver implements ObserverInterface
{
private $webhookService;
public function __construct(WebhookService $webhookService)
{
$this->webhookService = $webhookService;
}
public function execute(Observer $observer)
{
$cart = $observer->getEvent()->getCart();
$this->webhookService->sendWebhook('cart_update', $cart->getData());
}
}
5. Enable the module:
Run the following commands in the terminal:
php bin/magento module:enable Webhook_Notification php bin/magento setup:upgrade php bin/magento cache:clean
By following these steps, you will have created a basic Magento 2 module named `Webhook_Notification` that defines a web API endpoint for handling webhook notifications.
Solution 2: Use a Webhook extension
Alternatively, if you prefer not to develop a custom module, you can explore existing webhook extensions provided by third-party Magento vendors (like Mageplaza). Many extension providers offer ready-made solutions that allow you to configure and manage webhook notifications without requiring extensive coding.
Hope this works for you!
