Webhook delivery
Fast, reliable webhooks without the babysitting.
Queue, sign, and retry automatically—start delivering in minutes.
How it works
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.
2) Store and queue
Payload is stored durably, queued instantly, and scheduled with backoff + jitter.
3) Deliver with confidence
Workers sign requests (HMAC-SHA256), deliver fast, and retry automatically. You get logs and metrics.
Reliability & performance
Retries, backoff, and speed baked in.
- Exponential backoff with jitter and a dead-letter queue for exhausted attempts.
- Durable, encrypted payload storage and time-ordered UUIDs.
- Endpoint-level rate limiting and burst controls.
- Replay support and idempotent sends to avoid duplicates.
What you get
- Fast workers tuned for low latency delivery.
- Structured logs and metrics API for observability.
- Configurable retry policies per project.
- HTTPS-only outbound for safer deliveries.
Security
Signatures, encryption, and transport safety.
HMAC signatures
Every delivery includes `X-Webhook-Timestamp` and `X-Webhook-Signature` (HMAC-SHA256) with replay window checks.
Encryption by default
Payloads encrypted at rest; secrets stored in dedicated secret storage; API keys hashed (argon2id/bcrypt).
Transport controls
TLS 1.2+ everywhere. Customer endpoints must be HTTPS before delivery begins.
SDKs
Ship in minutes. Same API across SDKs.
curl -X POST https://api.testing-hookbridge.io/v1/webhooks/send \\
-H "Authorization: Bearer wrc_live_123" \\
-H "Content-Type: application/json" \\
-d '{
"endpoint": "https://example.com/hooks",
"payload": {"user_id": "abc123", "event": "signup"},
"hmac": true
}'

FAQ
Answers to common questions
How do retries work?
We retry with exponential backoff and jitter, then move to a dead-letter queue for later replay.
How do I verify signatures?
Use the `X-Webhook-Timestamp` and `X-Webhook-Signature` headers to compute HMAC-SHA256 over `timestamp.body` with your secret and compare in constant time.
Do you store payloads?
Yes—payloads are stored durably and encrypted at rest so you can replay deliveries and inspect failures safely.
Is HTTPS required?
Yes. We only deliver to HTTPS endpoints to keep transport secure.
How fast is delivery?
Messages are enqueued in milliseconds and dispatched by low-latency workers. Retries schedule automatically.
Can I replay failures?
Yes. Failed deliveries land in a dead-letter queue and can be replayed from the console or API.
