Welcome to Relae

Relae is a webhook relay service that ensures 100% delivery reliability for your critical webhook events. We sit between your vendors (like Stripe, Shopify, GitHub, etc.) and your application, providing automatic retries, monitoring, and a dead letter queue for failed events.

Why Relae?​

Webhooks are critical for real-time integrations, but they're notoriously unreliable:

  • ❌ Lost events when your server is down
  • ❌ No retry mechanism from most vendors
  • ❌ Difficult to debug webhook failures
  • ❌ Security concerns with unverified webhooks
  • ❌ Manual monitoring required

Relae solves all of this​

  • ✅ Guaranteed delivery with automatic retries
  • ✅ Dead letter queue to never lose an event
  • ✅ Real-time monitoring and analytics
  • ✅ HMAC signature verification for security
  • ✅ Automatic retry with exponential backoff
  • ✅ Per-vendor endpoint isolation for security

How It Works​

  1. Vendor sends webhook → Your vendor sends a webhook to your unique Relae endpoint
  2. Relae receives & validates → We validate the signature (if configured) and store the event
  3. Forward to your app → We forward the webhook to your destination URL with custom headers
  4. Automatic retries → If delivery fails, we retry up to 5 times with exponential backoff
  5. Dead Letter Queue → Failed events go to the DLQ where you can review and manually retry

Key Features​

🔄 Automatic Retries​

Failed webhooks are retried automatically (up to 5 times) with exponential backoff before moving to the dead letter queue.

📬 Dead Letter Queue​

Never lose a webhook. All failed events are stored in a DLQ where you can review, debug, and manually retry them.

🔐 Security First​

  • Incoming verification: Validate webhooks from vendors using their signature secrets
  • Outgoing signing: All forwarded webhooks include an HMAC-SHA256 signature you can verify
  • Per-endpoint isolation: Each vendor gets its own unique endpoint that can be rotated independently

📊 Analytics & Monitoring​

Track delivery rates, response times, and failure patterns with detailed analytics (Scale tier and above).

⚡ Lightning Fast​

Sub-100ms processing and forwarding times. Your webhooks are delivered in real-time.

🎯 Custom Headers​

Add authentication tokens, API keys, or any custom headers to forwarded webhooks.
