📥 Installation

You can install the package via composer:

composer require andreagroferreira/laravel-webhook-owlery

After installing the package, publish the configuration file and migrations:

php artisan vendor:publish --provider="WizardingCode\WebhookOwlery\WebhookOwleryServiceProvider"
php artisan migrate

Optional Dependencies

The package supports various signature validation methods. Some of these require additional libraries:

JWT Validation

To use JWT signature validation, you need to install the Firebase JWT library:

composer require firebase/php-jwt

Without this library, JWT validation will not be available, and the related tests will be skipped with a "JWT library not installed" message.

⚡ Quick Start

Receiving Webhooks

Configure an endpoint in your webhook-owlery.php config file:

'endpoints' => [
    'stripe' => [
        'path' => '/webhooks/stripe',
        'secret' => env('STRIPE_WEBHOOK_SECRET'),
        'validator' => 'hmac',
    ],
],

Create a handler for incoming webhooks:

namespace App\Listeners;

use WizardingCode\WebhookOwlery\Events\WebhookReceived;

class ProcessStripeWebhook
{
    public function handle(WebhookReceived $event)
    {
        $payload = $event->payload;
        $event = $payload['type'] ?? null;
        
        if ($event === 'charge.succeeded') {
            // Process the successful charge
        }
    }
}

protected $listen = [
    \WizardingCode\WebhookOwlery\Events\WebhookReceived::class => [
        \App\Listeners\ProcessStripeWebhook::class,
    ],
];

That's it! Your application is now ready to receive webhooks at /api/webhooks/stripe.

Sending Webhooks

use WizardingCode\WebhookOwlery\Facades\Owlery;

// Simple webhook
Owlery::send('user.created', ['user' => $user->toArray()]);

// With specific subscriptions
Owlery::to(['subscription-id-1', 'subscription-id-2'])
      ->send('order.shipped', ['order' => $order->toArray()]);

// With metadata
Owlery::withMetadata(['source' => 'backend', 'initiated_by' => 'system'])
      ->send('payment.failed', ['payment' => $payment->toArray()]);

Command-line Tools

The package includes several useful Artisan commands:

# Generate a secure webhook secret
php artisan webhook:generate-secret

# List all configured webhook endpoints
php artisan webhook:list-endpoints

# Clean up old webhook data
php artisan webhook:cleanup

🛠️ Usage Examples

Managing Webhook Subscriptions

use WizardingCode\WebhookOwlery\Facades\WebhookRepository;

// Create a new webhook endpoint
$endpoint = WebhookRepository::createEndpoint([
    'url' => 'https://example.com/webhook',
    'description' => 'My application webhook endpoint',
    'secret' => Str::random(64),
    'is_active' => true,
]);

// Create a new webhook subscription
$subscription = WebhookRepository::createSubscription([
    'endpoint_id' => $endpoint->id,
    'event_types' => ['user.created', 'user.updated'],
    'description' => 'User events subscription',
    'is_active' => true,
]);

// Update subscription
WebhookRepository::updateSubscription($subscription->id, [
    'event_types' => ['user.created', 'user.updated', 'user.deleted'],
]);

// Deactivate subscription
WebhookRepository::updateSubscription($subscription->id, [
    'is_active' => false,
]);

// Find endpoints and subscriptions
$activeEndpoints = WebhookRepository::getActiveEndpoints();
$userSubscriptions = WebhookRepository::getSubscriptionsByEventType('user.created');

// Get delivery statistics
$stats = WebhookRepository::getDeliveryStatistics();

Adding a New Provider

1. Create a Provider-Specific Request

namespace App\Http\Requests\Webhooks;

use WizardingCode\WebhookOwlery\Http\Requests\WebhookReceiveRequest;

class SlackWebhookRequest extends WebhookReceiveRequest
{
    public function rules()
    {
        return [
            'event' => 'required|string',
            'team_id' => 'required|string',
            'api_app_id' => 'required|string',
            'event_id' => 'required|string',
            'event_time' => 'required|integer',
            'payload' => 'required|array',
        ];
    }
    
    public function getEventType()
    {
        return 'slack.' . ($this->input('event.type') ?? 'unknown');
    }
    
    public function getPayload()
    {
        return [
            'event' => $this->input('event'),
            'team_id' => $this->input('team_id'),
            'event_id' => $this->input('event_id'),
            'event_time' => $this->input('event_time'),
            'payload' => $this->input('payload'),
        ];
    }
}

2. Create a Provider-Specific Validator

namespace App\Validators;

use WizardingCode\WebhookOwlery\Contracts\SignatureValidatorContract;
use Illuminate\Http\Request;

class SlackSignatureValidator implements SignatureValidatorContract
{
    public function validate(Request $request, string $secret): bool
    {
        $signature = $request->header('X-Slack-Signature');
        $timestamp = $request->header('X-Slack-Request-Timestamp');
        
        // Check if the request is not older than 5 minutes
        $now = time();
        if (abs($now - $timestamp) > 300) {
            return false;
        }
        
        $payload = $request->getContent();
        $baseString = 'v0:' . $timestamp . ':' . $payload;
        
        // Compute signature using the secret
        $computedSignature = 'v0=' . hash_hmac('sha256', $baseString, $secret);
        
        // Compare signatures using constant-time comparison
        return hash_equals($computedSignature, $signature);
    }
}

3. Register the Provider in a Service Provider

namespace App\Providers;

use App\Http\Requests\Webhooks\SlackWebhookRequest;
use App\Validators\SlackSignatureValidator;
use WizardingCode\WebhookOwlery\Facades\Owlery;
use WizardingCode\WebhookOwlery\Facades\WebhookReceiver;
use Illuminate\Support\ServiceProvider;

class WebhookServiceProvider extends ServiceProvider
{
    public function boot()
    {
        // Register the signature validator
        Owlery::validator('slack', SlackSignatureValidator::class);
        
        // Register the request handler
        WebhookReceiver::registerProvider('slack', SlackWebhookRequest::class);
    }
}

4. Add Configuration for the Provider

Update your config/webhook-owlery.php file:

'endpoints' => [
    // ... other providers
    'slack' => [
        'path' => '/webhooks/slack',
        'secret' => env('SLACK_SIGNING_SECRET'),
        'validator' => 'slack',
        'signature_header' => 'X-Slack-Signature',
        'rate_limit' => [
            'enabled' => true,
            'attempts' => 60,
            'decay_minutes' => 1,
        ],
    ],
],

5. Create an Event Listener for the Provider

namespace App\Listeners;

use WizardingCode\WebhookOwlery\Events\WebhookReceived;
use Illuminate\Support\Facades\Log;

class HandleSlackWebhooks
{
    public function handle(WebhookReceived $event)
    {
        if ($event->endpoint !== 'slack') {
            return;
        }
        
        $payload = $event->payload;
        $eventType = $payload['event']['type'] ?? 'unknown';
        
        Log::info('Received Slack webhook', [
            'event_type' => $eventType,
            'team_id' => $payload['team_id'],
        ]);
        
        // Process different Slack event types
        switch ($eventType) {
            case 'message':
                $this->handleMessage($payload);
                break;
                
            case 'app_mention':
                $this->handleAppMention($payload);
                break;
                
            // Handle other event types
        }
    }
    
    protected function handleMessage(array $payload)
    {
        $message = $payload['event']['text'] ?? '';
        $user = $payload['event']['user'] ?? '';
        $channel = $payload['event']['channel'] ?? '';
        
        // Process the message
    }
    
    protected function handleAppMention(array $payload)
    {
        $mention = $payload['event']['text'] ?? '';
        $user = $payload['event']['user'] ?? '';
        $channel = $payload['event']['channel'] ?? '';
        
        // Process the app mention
    }
}

6. Register the Event Listener

In your EventServiceProvider.php:

protected $listen = [
    \WizardingCode\WebhookOwlery\Events\WebhookReceived::class => [
        // ... other listeners
        \App\Listeners\HandleSlackWebhooks::class,
    ],
];

Custom Signature Validation

// Create a custom validator
namespace App\Validators;

use WizardingCode\WebhookOwlery\Contracts\SignatureValidatorContract;
use Illuminate\Http\Request;

class CustomValidator implements SignatureValidatorContract
{
    public function validate(Request $request, string $secret): bool
    {
        $signature = $request->header('X-Custom-Signature');
        $payload = $request->getContent();
        
        // Your custom validation logic
        $expectedSignature = hash_hmac('sha512', $payload, $secret);
        
        return hash_equals($expectedSignature, $signature);
    }
}

use WizardingCode\WebhookOwlery\Facades\Owlery;

public function boot()
{
    Owlery::validator('custom', \App\Validators\CustomValidator::class);
}

Advanced Webhook Dispatch

use WizardingCode\WebhookOwlery\Facades\Owlery;

// With custom retry strategy
Owlery::withRetry([
    'attempts' => 5,
    'backoff' => [1, 5, 15, 30, 60], // minutes
])
->send('invoice.paid', ['invoice' => $invoice->toArray()]);

// With conditional recipients
$subscribers = $company->partners->pluck('webhook_subscription_id')->toArray();

Owlery::to($subscribers)
      ->withMetadata([
          'company_id' => $company->id,
          'importance' => 'high',
      ])
      ->send('product.released', ['product' => $product->toArray()]);

// With conditional dispatching
Owlery::when($order->total > 1000)
      ->send('order.high_value', ['order' => $order->toArray()]);

// With custom headers
Owlery::withHeaders([
    'X-Custom-Header' => 'custom-value',
    'X-Source-System' => 'inventory',
])
->send('inventory.updated', ['product' => $product->toArray()]);

// With batch sending
Owlery::batch([
    ['event' => 'user.created', 'payload' => ['user' => $user->toArray()]],
    ['event' => 'profile.created', 'payload' => ['profile' => $profile->toArray()]],
    ['event' => 'preferences.set', 'payload' => ['preferences' => $preferences]],
])
->send();

Real-World Example: E-commerce Order Flow

namespace App\Services;

use App\Models\Order;
use WizardingCode\WebhookOwlery\Facades\Owlery;

class OrderProcessor
{
    public function processOrder(Order $order)
    {
        // Process the order...
        
        // Notify systems about new order
        Owlery::send('order.created', [
            'order' => [
                'id' => $order->id,
                'reference' => $order->reference,
                'total' => $order->total,
                'currency' => $order->currency,
                'status' => $order->status,
                'created_at' => $order->created_at,
            ],
            'customer' => [
                'id' => $order->customer->id,
                'email' => $order->customer->email,
            ],
            'items' => $order->items->map(function ($item) {
                return [
                    'product_id' => $item->product_id,
                    'quantity' => $item->quantity,
                    'price' => $item->price,
                ];
            })->toArray(),
        ]);
        
        // If it's a large order, notify VIP system with high priority
        if ($order->total > 1000) {

Handling Incoming Webhooks: Stripe Example

namespace App\Listeners;

use WizardingCode\WebhookOwlery\Events\WebhookReceived;

Building a Customized Webhook Dispatcher

This example shows how to extend the basic functionality with a specialized webhook dispatcher:

namespace App\Services;

use WizardingCode\WebhookOwlery\Facades\Owlery;
use WizardingCode\WebhookOwlery\Facades\WebhookRepository;
use Illuminate\Support\Collection;

class EnhancedWebhookDispatcher
{
    /**
     * Send webhooks to subscriptions based on tags
     */
    public function sendToTags(array $tags, string $eventType, array $payload, array $options = [])
    {
        // Find all subscriptions with the given tags
        $subscriptions = WebhookRepository::getSubscriptionsByTags($tags);
        
        if ($subscriptions->isEmpty()) {
            return;
        }
        
        return $this->dispatchToSubscriptions($subscriptions, $eventType, $payload, $options);
    }
    
    /**
     * Send webhooks to a subset of subscriptions based on a filter
     */
    public function sendToFiltered(callable $filter, string $eventType, array $payload, array $options = [])
    {
        // Get all subscriptions for the event type
        $allSubscriptions = WebhookRepository::getSubscriptionsByEventType($eventType);
        
        // Filter the subscriptions
        $filteredSubscriptions = $allSubscriptions->filter($filter);
        
        if ($filteredSubscriptions->isEmpty()) {
            return;
        }
        
        return $this->dispatchToSubscriptions($filteredSubscriptions, $eventType, $payload, $options);
    }
    
    /**
     * Send feature announcements to all active subscriptions
     */
    public function announceFeature(string $featureName, array $featureDetails, array $options = [])
    {
        // Prepare the payload
        $payload = [
            'feature' => $featureName,
            'details' => $featureDetails,
            'announced_at' => now()->toIso8601String(),
        ];
        
        // Set default options
        $options = array_merge([
            'retry' => [
                'attempts' => 5,
                'backoff' => [5, 15, 30, 60, 120], // minutes
            ],
            'metadata' => [
                'importance' => 'announcement',
                'source' => 'product-team',
            ],
        ], $options);
        
        // Get all active subscriptions
        $activeSubscriptions = WebhookRepository::getActiveSubscriptions();
        
        return $this->dispatchToSubscriptions($activeSubscriptions, 'feature.announced', $payload, $options);
    }
    
    /**
     * Dispatch webhooks to multiple subscriptions with options
     */
    protected function dispatchToSubscriptions(Collection $subscriptions, string $eventType, array $payload, array $options = [])
    {
        $subscriptionIds = $subscriptions->pluck('id')->toArray();
        
        $dispatcher = Owlery::to($subscriptionIds);
        
        // Apply retry strategy if provided
        if (isset($options['retry'])) {
            $dispatcher->withRetry($options['retry']);
        }
        
        // Apply metadata if provided
        if (isset($options['metadata'])) {
            $dispatcher->withMetadata($options['metadata']);
        }
        
        // Apply headers if provided
        if (isset($options['headers'])) {
            $dispatcher->withHeaders($options['headers']);
        }
        
        return $dispatcher->send($eventType, $payload);
    }
}

Usage of the custom dispatcher:

// Send to subscriptions with specific tags
$dispatcher = new EnhancedWebhookDispatcher();
$dispatcher->sendToTags(['billing', 'finance'], 'invoice.paid', [
    'invoice' => $invoice->toArray(),
]);

// Send to filtered subscriptions
$dispatcher->sendToFiltered(function ($subscription) use ($user) {
    // Only send to subscriptions belonging to the user's organization
    return $subscription->organization_id === $user->organization_id;
}, 'project.created', [
    'project' => $project->toArray(),
]);

// Announce a new feature
$dispatcher->announceFeature('Advanced Analytics', [
    'name' => 'Advanced Analytics',
    'description' => 'Track detailed metrics with our new analytics dashboard',
    'documentation_url' => 'https://docs.example.com/advanced-analytics',
    'available_from' => now()->addDays(7)->toIso8601String(),
]);

🧪 Testing

The package ships with a comprehensive test suite using Pest PHP.

Running Unit Tests

To run the unit tests (all currently passing):

composer test
# or specifically
vendor/bin/pest --group=unit

Output:

PASS  Tests\Unit\CircuitBreakerTest
PASS  Tests\Unit\HmacSignatureValidatorTest
PASS  Tests\Unit\OwleryTest
PASS  Tests\Unit\Validators\ApiKeyValidatorTest
PASS  Tests\Unit\Validators\BasicAuthValidatorTest
WARN  Tests\Unit\Validators\JwtSignatureValidatorTest (Skipped - JWT library not installed)
PASS  Tests\Unit\WebhookDispatcherTest
PASS  Tests\Unit\WebhookRepositoryTest

Tests:  4 skipped, 33 passed (70 assertions)

Note: Feature tests are currently being refined and will be available in a future release. The core functionality is fully tested with unit tests.

GitHub Actions CI

The CI pipeline is configured to run all unit tests against multiple PHP and Laravel versions. Feature tests are excluded from the CI pipeline until they are fully stabilized in a future release.

Note: The skipped tests for JWT validation will automatically run if you install the Firebase JWT library with composer require firebase/php-jwt. This is expected behavior as the JWT functionality is considered optional.

Generate Webhook Secret

php artisan webhook:generate-secret

Generates a secure random string to use as a webhook secret. Options include:

# Generate with custom length
php artisan webhook:generate-secret --length=64

# Generate and copy to clipboard
php artisan webhook:generate-secret --copy

# Generate with custom prefix
php artisan webhook:generate-secret --prefix="whsec_"

List Webhook Endpoints

php artisan webhook:list-endpoints

Lists all configured webhook endpoints with their status. Available filters:

# Show only active endpoints
php artisan webhook:list-endpoints --active

# Show only inactive endpoints
php artisan webhook:list-endpoints --inactive

# Show detailed information
php artisan webhook:list-endpoints --details

Cleanup Webhooks

php artisan webhook:cleanup

Removes old webhook data based on your retention settings. Options include:

# Custom retention period
php artisan webhook:cleanup --days=60

# Specific retention periods for different types
php artisan webhook:cleanup --success-days=7 --failed-days=30

# Dry run (shows what would be deleted without actually deleting)
php artisan webhook:cleanup --dry-run

📊 Dashboard Integration

Laravel Webhook Owlery is designed to be dashboard-friendly. Its data structures make it easy to build monitoring dashboards with information on:

Webhook delivery success/failure rates
Latency metrics
Error patterns
Most active subscriptions/endpoints
Circuit breaker status

Example Dashboard Queries

// Get webhook delivery summary
$summary = DB::table('webhook_deliveries')
    ->select(
        DB::raw('DATE(created_at) as date'),
        DB::raw('COUNT(*) as total'),
        DB::raw('SUM(CASE WHEN status = "success" THEN 1 ELSE 0 END) as successful'),
        DB::raw('SUM(CASE WHEN status = "failed" THEN 1 ELSE 0 END) as failed'),
        DB::raw('AVG(CASE WHEN status = "success" THEN response_time ELSE NULL END) as avg_response_time')

🔒 Security

Webhook Owlery takes security seriously:

All secrets are stored encrypted in the database
Signatures are validated using constant-time comparison to prevent timing attacks
Rate limiting protects against abuse
Circuit breaker prevents cascading failures
Detailed logging for audit trails

Signature Validation Methods

The package supports multiple signature validation methods:

HMAC Signatures - The default and most common method (no additional dependencies required)
JWT Validation - Requires the Firebase JWT library (composer require firebase/php-jwt)
API Key Validation - Simple validation with API keys (no additional dependencies required)
Basic Auth Validation - Username/password validation (no additional dependencies required)
Custom Validators - Create your own validators for specific providers

Security Best Practices

Always use HTTPS for webhook endpoints
Rotate webhook secrets periodically
Use the built-in rate limiting to prevent abuse
Monitor webhook deliveries for unusual patterns
Use the circuit breaker to prevent cascading failures
Validate all incoming webhook data before processing
Store webhook secrets securely using environment variables
Choose the appropriate validation method based on your security requirements
