📥 Installation

You can install the package via composer:

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

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:

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

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

2. Create a handler for incoming webhooks:

3. Register your handler in your EventServiceProvider:

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

🧪 Testing

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

Running Unit Tests

To run the unit tests (all currently passing):

Output:

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.

Writing Tests for Webhook Handling

⚙️ Artisan Commands

Laravel Webhook Owlery comes with several helpful Artisan commands:

Generate Webhook Secret

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

List Webhook Endpoints

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

Cleanup Webhooks

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

📊 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

🔒 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:

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

Security Best Practices

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