README

A reusable Laravel package for receiving, processing, and managing incoming webhooks reliably. It handles webhooks from multiple providers, prevents duplicates, and ensures high reliability for critical backend systems.

Features

• Signature Verification: Ensures incoming requests are authentic using HMAC-SHA256.
• Automatic Duplicate Prevention: Uses unique job IDs to prevent duplicate processing.
• Reliable Processing: Queue-based asynchronous processing with automatic retries.
• Event Dispatching: Fires Laravel events (WebhookReceived) for easy integration.
• Configurable: Customizable retry intervals, queue names, signature secrets, and more.
• Multiple Providers: Support for Stripe, PayPal, GitHub, and more.

Installation

Requirements

• PHP: ^8.2
• Laravel: ^10.0 || ^11.0 || ^12.0

Via Composer

composer require ayodvr/laravel-webhook-manager

Publish Configuration

Publish the configuration file:

php artisan vendor:publish --tag=webhook-config

Publish Migration

Run the migration to create the webhook events table:

php artisan migrate

Set your webhook signature secret in your .env file:

WEBHOOK_SIGNATURE_SECRET=your-secret-key-here

For Paystack Setup

1. Get your webhook secret from the Paystack Dashboard → Settings → API Keys & Webhooks
2. Set webhook URL to: https://your-domain.com/webhooks/paystack
3. Test webhook using Paystack's dashboard webhook tester

Usage

Receiving Webhooks

Webhooks are automatically handled at the /webhooks/{provider} route. For example:

• Stripe: POST /webhooks/stripe
• PayPal: POST /webhooks/paypal

Configure your webhook providers to send POST requests to these URLs with a X-Webhook-Signature header containing the HMAC-SHA256 signature of the request body.

Listening to Webhooks

Listen to the WebhookReceived event to process webhook data:

<?php

namespace App\Listeners;

use Cybrox\WebhookManager\Events\WebhookReceived;

class ProcessStripeWebhook
{
    public function handle(WebhookReceived $event): void
    {
        $webhookEvent = $event->webhookEvent;

        // Process the webhook based on provider and event type
        switch ($webhookEvent->provider) {
            case 'stripe':
                $this->handleStripeWebhook($webhookEvent);
                break;
            case 'paypal':
                $this->handlePaypalWebhook($webhookEvent);
                break;
            // Add more providers as needed
        }
    }

    private function handleStripeWebhook($event)
    {
        $payload = json_decode($event->payload, true);

        // Example: Handle payment succeeded
        if ($event->event_type === 'payment.succeeded') {
            // Update order status, send notifications, etc.
        }
    }
}

Register the listener in EventServiceProvider:

protected $listen = [
    WebhookReceived::class => [
        ProcessStripeWebhook::class,
    ],
];

Configuration Options

Edit config/webhook-manager.php to customize behavior:

return [
    'signature_secret' => env('WEBHOOK_SIGNATURE_SECRET'),
    'max_attempts' => env('WEBHOOK_MAX_ATTEMPTS', 3),
    'queue' => env('WEBHOOK_QUEUE', 'webhooks'),
    'providers' => [
        'stripe',
        'paypal',
        'github',
    ],
];

Security

• Webhooks are verified using HMAC-SHA256 signatures.
• Use HTTPS in production.
• Store signature secrets securely as environment variables.

Testing

Run the test suite:

php artisan test tests/Feature/WebhookTest.php
