Production-grade webhook delivery.
One API call to send a webhook. Hookbridge signs, queues, retries, rate-limits, and delivers—with full observability and alerting at every step.
Send once. We handle the rest.
1. Send to Hookbridge
POST your webhook payload to our API with your project key. HTTPS enforced, idempotency supported. You get a message ID back immediately.
2. Store, sign, and deliver
Payload is stored durably and signed with HMAC-SHA256. Delivery is attempted immediately. If it fails, we retry automatically with backoff.
3. Monitor and recover
Full delivery logs with HTTP timing breakdowns. Alerts when endpoints fail. Replay any delivery from the console or API.
Your customers can trust every delivery.
HMAC-SHA256 signatures
Every outbound webhook is signed with HMAC-SHA256. Timestamp headers are included so your customers can reject replayed requests outside the verification window.
Signing key rotation
Rotate signing keys with configurable overlap periods. Old keys stay valid during the transition window so your customers don't see verification failures during a rotation.
Constant-time signature checks
Signature verification uses constant-time comparison to prevent timing attacks. Your customers get cryptographically sound verification with our SDKs or their own implementation.
HTTPS-only delivery
All outbound deliveries are sent over HTTPS with TLS 1.2+. Payloads are encrypted at rest and in transit. No plaintext delivery, no exceptions.
Resilient delivery that handles real-world failures.
Two-tier retry system
Fast retries with exponential backoff and jitter for transient failures like timeouts and 5xx responses. A separate slow-retry tier handles persistent issues with longer intervals, giving endpoints time to recover.
Dead-letter queue
When all retry attempts are exhausted, the message moves to a dead-letter queue. Nothing is silently dropped. Review, debug, and replay failed deliveries whenever you're ready.
Idempotent delivery
Send the same webhook with an idempotency key and Hookbridge ensures it's only delivered once. Safely retry from your application code without worrying about duplicates.
Respect your customers' infrastructure.
Per-endpoint rate limiting
Set rate limits individually for each destination. Hookbridge queues excess deliveries and sends them within the limit—no manual throttling, no dropped events.
Burst capacity
Configure burst allowances so endpoints can absorb short spikes without triggering rate limit delays. Useful for endpoints that handle bursts well but need sustained-rate protection.
Configurable timeouts
Set per-endpoint timeout thresholds. Slow endpoints don't hold up deliveries to fast ones. Each destination is tuned independently.
Connection management
Connection pooling and DNS caching reduce latency and avoid exhausting destination resources. Hookbridge manages the connection lifecycle so you don't have to.
Know what's happening. Get notified when it goes wrong.
Delivery logs
Every attempt logged with HTTP status, response body, and headers. See exactly what your customer's endpoint returned.
HTTP timing breakdowns
Per-attempt timing for DNS resolution, TCP connect, TLS handshake, and time to first byte. Pinpoint where slowdowns occur.
Slack & email alerts
Get notified when endpoints start failing. Configure thresholds and severity levels so you know about problems before your customers do.
Metrics API
Success rates, latency percentiles, and failure breakdowns per endpoint. Pull into your own dashboards or use the console.
Fix it and replay. No manual reconstruction.
One-click replay
Replay any delivery from the console or API while the payload is still in retention. The original payload is delivered exactly as it was, with a fresh signature and timestamp.
Replay guardrails
Max replay limits, delivery status checks, and rate limiting on replays prevent accidental duplicate sends. Guardrails are built in so replays are safe by default.
CSV exports
Export delivery logs filtered by status, endpoint, or time range. Share with your team, feed into analytics, or use for incident post-mortems.
