Webhook delivery
Fast, reliable webhooks — send and receive.
Queue, sign, and retry automatically — outbound and inbound, handled for you.
Reliability & performance
Retries, backoff, and speed baked in.
- Exponential backoff with jitter and a dead-letter queue for exhausted attempts.
- Durable, encrypted payload storage with unique message IDs.
- 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.
- Logs and metrics API for full observability.
- Manual replay for any message from the console or API.
- Idempotency keys to prevent duplicate 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
All data encrypted at rest and in transit. API keys securely hashed.
Transport controls
TLS 1.2+ everywhere. Customer endpoints must be HTTPS before delivery begins.
Highlights
Fast by default
Enqueue in milliseconds and push via tuned workers for low-latency delivery.
Retries handled
Exponential backoff with jitter, dead-letter queue after configured attempts, replay when you're ready.
Secure delivery
HMAC signatures, HTTPS-only outbound, encrypted payload storage by default.
Observability
Structured logs and metrics API plus console views for quick debugging.

FAQ
Answers to common questions
How do retries work?
Failed deliveries are retried automatically with exponential backoff and jitter. You can also manually replay any message from the console or API.
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.
How are payloads protected?
All payloads are encrypted at rest and in transit. We retain them only as long as needed for delivery, retries, and observability, then delete them automatically.
How is data encrypted?
All data is encrypted at rest and in transit. Transport uses TLS 1.2+ and we enforce HTTPS on every endpoint.
How fast is delivery?
Messages are enqueued in milliseconds and the first delivery attempt is made immediately. Total delivery time depends on your endpoint's response speed.
Can I replay messages?
Yes. Any message can be replayed manually from the console or API whenever you need to redeliver.
