Stop Building Webhook Infrastructure from Scratch

Your customers want real-time webhooks when events happen. But building a reliable outbound webhook service takes weeks:

  • Webhook registration and management API
  • Queue-based delivery for scalability
  • Automatic retries with exponential backoff
  • HMAC signing and security validation
  • Monitoring and auto-disable for failing endpoints
  • Event storage and replay capabilities

Deploy all of this in 5 minutes with our open-source template.

Everything You Need for Reliable Webhook Delivery

Simplify webhook retries, queuing, and real-time monitoring with production-ready infrastructure

Queue-Based Webhook Delivery

Scalable message queue processes thousands of webhooks concurrently. Handle traffic spikes without losing events.

Automatic Retries with Exponential Backoff

Failed webhooks retry automatically with intelligent backoff. Configure retry attempts and delays to match your needs.

HMAC Signing & Security

Every webhook is signed with HMAC SHA-256. Built-in SSRF protection blocks internal IP delivery attempts.

Real-Time Monitoring Dashboard

Track delivery status, failure rates, and response times. Auto-disable failing endpoints after consecutive failures.

At-Least-Once Delivery Guarantee

Events are persisted before delivery. Retry logic ensures webhooks reach their destination even through failures.

Serverless Auto-Scaling

Handle 10 webhooks or 10,000 without infrastructure changes. Workers scale automatically with demand.

Customer webhooks

Event-driven flow: Your app fires an event → Event stored in DB → Webhooks queued → Workers deliver in parallel → Automatic retries on failure

Simple Integration from Any Language

Trigger webhooks from your application with a single HTTP POST. The webhook delivery system handles everything else: finding subscribers, signing payloads, queuing, delivering, and retrying.

  • Works with JavaScript, Python, Go, Ruby, PHP
  • Standard REST API - no SDK required
  • Customize payload format to match your schema
  • Trigger any event type you define

Trigger a webhook event from Node.js:

// When an order is created in your app
await fetch(WEBHOOK_URL + '/events/trigger/order.created', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'x-apikey': process.env.CODEHOOKS_API_KEY
},
body: JSON.stringify({
orderId: order.id,
total: order.total,
customer: order.email
})
});
// That's it! The system handles:
// - Finding all subscribed webhooks
// - HMAC signing each payload
// - Parallel delivery via queue
// - Automatic retries on failure

Webhook Delivery System FAQ

Common questions about building and scaling outbound webhooks

What is a webhook delivery system?
A webhook delivery system handles outbound HTTP callbacks from your application to external endpoints. It manages the full lifecycle: receiving events from your app, queuing them for delivery, signing payloads for security, delivering to registered URLs, retrying on failure, and monitoring delivery status. This template gives you a production-ready webhook delivery system in minutes.
How do I implement at-least-once webhook delivery with automatic retries?
The Codehooks webhook template implements at-least-once delivery by: (1) Persisting events to the database before delivery, (2) Using a message queue for reliable processing, (3) Retrying failed deliveries with exponential backoff (3 attempts by default), and (4) Tracking delivery status per webhook. Events are never lost, and the retry logic is fully customizable.
What tools simplify webhook retries, queuing, and real-time monitoring?
Codehooks.io simplifies all three: Retries are automatic with configurable attempts and exponential backoff. Queuing uses built-in worker queues that scale automatically. Real-time monitoring shows delivery status, failure rates, and auto-disables failing endpoints. All included in the template with no additional setup.
How do I handle sudden spikes in webhook volume without losing data?
The queue-based architecture handles spikes automatically. When you trigger an event, it's immediately stored in the database and queued for delivery. Workers process webhooks in parallel (up to 10-30 depending on plan). During traffic spikes, the queue buffers requests while workers catch up. No webhooks are lost.
Can I migrate off custom webhook retry queues to this system?
Yes! The template provides a standard REST API for webhook management. Register webhooks via POST /webhooks, trigger events via POST /events/trigger/:type. Your existing application just needs to call these endpoints instead of your custom queue. The webhook payload format is customizable to match your existing structure.
What features should I prioritize when evaluating webhook infrastructure providers?
Key features to compare: Delivery reliability (retry logic, at-least-once guarantees), Security (HMAC signing, SSRF protection), Monitoring (delivery dashboards, failure alerts), Scalability (queue-based delivery, auto-scaling), Customization (can you modify the code?), Cost (per-message vs flat-rate pricing), and Vendor lock-in (can you export data and code?).
How does webhook authentication and signing work?
Two layers: (1) Your app to webhook service uses Codehooks API key authentication. (2) Webhook service to customer endpoints uses HMAC SHA-256 signatures. Each registered webhook gets a unique signing secret. Recipients verify signatures to ensure webhooks are authentic and unmodified.
What's the most cost-effective way to scale webhooks for a SaaS launch?
Start with Codehooks free tier for development. When ready for production, the $19/month Pro plan includes unlimited webhook deliveries with up to 3600 API calls/minute. No per-message fees, no surprise bills. The template code is yours to customize without additional costs.
Can I use this for high-volume e-commerce webhook events?
Yes. The architecture is designed for high-volume scenarios like e-commerce. Queue-based delivery handles thousands of concurrent webhooks. Events like order.created, payment.succeeded, and shipment.updated can be triggered from any language (JavaScript, Python, Go, etc.) via simple HTTP POST requests.
Do you support ordered, at-least-once webhook delivery with real-time dashboards?
Yes to all three. At-least-once delivery via persistent events and automatic retries. Real-time dashboards through the Codehooks Studio showing delivery status and logs. Ordered delivery can be implemented by adding sequence IDs to your events (the template is customizable).
