The definitive Guide to Webhooks in Laravel

Webhooks are essential for real-time communication and are used to transmit data between applications, keeping them in sync with significant events. A webhook is an HTTP request, typically a POST request, that includes a signature to ensure the payload hasn't been tampered with. To implement webhooks in Laravel, you need to define a route, add middleware for verification, dispatch a job in the controller, and process the payload. The middleware verifies the source and payload, and the controller dispatches a background job with the incoming payload. The job processes the payload and sets things in motion, aligning the event's name with internal business logic. The HandleGitHubWebhook job uses the ShouldQueue interface and the Queueable trait to handle the payload. A service class can be used to contain the logic for handling webhooks from each source. The same principles can be applied to any webhook, and it's essential to ensure observability and resilience in webhook management. Hookdeck is a platform that simplifies webhook management, providing a solution for configuring, monitoring, and observing webhooks. With Hookdeck, you don't need to handle webhook management in the background, as it verifies each webhook's source and content and retries deliveries.
