Every message arrives
Retries, circuit breakers, dead letter queue, and cryptographic proof on every delivery.
You sent a webhook.
It failed.
You retried.
It failed again.
The endpoint came back an hour later.
Your retry budget was gone.
The event was lost.
Your customer never knew.
You never knew either.
Delivery should just work.
Now it does.
Automatic retry engine
Every event follows a precise path. Signature, delivery, retries, circuit breaker, and dead letter queue. No event disappears.
Per endpoint circuit breaker
Endpoints go down. The circuit breaker protects your system by pausing deliveries, probing periodically, and resuming automatically.
Monitor
Every delivery is tracked. Consecutive failures are counted in real time.
Trip
After five consecutive failures, the circuit breaker opens. Deliveries pause.
Probe
npayload sends periodic probes to detect when the endpoint recovers.
Resume
The endpoint responds. The circuit breaker closes. Pending deliveries resume in order.
Failed events are never lost.
Every event that fails after all retries lands in the dead letter queue. Inspect the failure reason, retry count, and timestamp. Replay individually or in bulk. No event disappears. No data is lost.
Cryptographic proof on every delivery
Every delivered event carries an HMAC SHA 256 signature. Your endpoint verifies authenticity and integrity without trusting the network.
Sign
npayload generates a unique HMAC SHA 256 signature for every delivery.
Deliver
The event and signature are sent together to your endpoint.
Verify
Your endpoint recomputes the signature and confirms authenticity and integrity.
Before and after npayload Delivery
Without npayload Delivery
- Custom retry logic in every service
- No visibility into failures
- Manual DLQ management
- No delivery proof
- Circuit breakers built from scratch
- Lost events discovered by customers
With npayload Delivery
- Automatic retries with configurable backoff
- Real time delivery dashboard
- Inspect and replay with one click
- HMAC signature on every delivery
- Built in circuit breaker per endpoint
- Dead letter queue catches everything
npayload vs. building it yourself
| Feature | npayload | Build it yourself |
|---|---|---|
