webhook.js

// That's the whole API.
const response = await fetch('https://hooksniff-api-1046140057667.europe-west1.run.app/v1/webhooks', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer hr_live_...',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    url: 'https://your-app.com/webhook',
    event: 'order.created',
    payload: { id: 'ord_123', total: 49.99 }
  })
})

Features

Everything you need. Nothing you don't.

Built for developers who want reliable webhooks without the complexity of a full event platform.

⟳

Reliable delivery

Automatic retries with exponential backoff. Failed webhooks are retried up to 5 times over 24 hours with jitter to avoid thundering herds.

🔐

HMAC signatures

Every webhook is signed with your secret. Verify the payload is authentic using standard HMAC-SHA256 — no custom crypto, no proprietary signing.

📊

Dashboard

Monitor every delivery in real-time. See success rates, response times, and error details. Filter by endpoint, event type, or status code.

⚡

Simple API

4 endpoints. That's it. Send a webhook, list deliveries, get a delivery, retry a delivery. RESTful JSON with predictable responses.
