How it works
A reliable path
for every event.
From the first database write to delivery or recovery, follow the components that carry each event.
The event and its outbox entry are committed in one database transaction. The API returns success after that commit, before webhook delivery.
- S3
- Large payload claim-checks & dead-letter archives.
- Redis
- Tenant rate limits & destination circuit breakers.
Accept the event
POST /events validates the tenant and payload, applies the ingestion limit and uploads oversized payloads to S3.
Atomic acceptance
The event and outbox entry share one PostgreSQL transaction. Acceptance means the event was saved, not that its endpoint has received it.
At-least-once delivery
Duplicate sends remain possible, including a crash after SQS accepts a publication or after the receiver accepts a webhook. Deduplicate by event ID at the receiver.
Bounded automatic retries
Failed attempts use exponential backoff with jitter and a configurable attempt limit. A permanently failing endpoint is not guaranteed eventual delivery.
Durable failure recovery
Exhausted deliveries retain a PostgreSQL dead-letter record and an S3 payload archive. Explicit replay creates a new event and outbox entry; it is not automatic.
Delivery semantics: at-least-once, with bounded retries. Receivers must tolerate duplicates.
Features
Everything you need
for reliable delivery.
From ingestion to recovery, the pieces to deliver webhooks and understand their outcome.
Transactional outbox
Commit the event and its outbox entry together, then publish saved work to SQS.
Retries and backoff
Retry failed deliveries with exponential backoff, jitter and a bounded attempt budget.
Dead-letter recovery
Inspect archived payloads and explicitly replay a failed delivery as a new event.
Multi-tenant fairness
Rotate outbox publication across tenants and bound each tenant’s dispatch turns.
Secure delivery
Verify outbound webhook authenticity with a tenant-specific HMAC-SHA256 signature.
Delivery visibility
Query delivery status, attempt counts and retry state through replica-backed history APIs.
Built for developers
Integrate
in minutes.
One endpoint. A familiar request. Connect your application using the tools you already work with.
Start with plain HTTP
Send a tenant ID, event type and JSON payload. Use your own HTTP client.
Keep the receiver verifiable
Workers sign each outgoing webhook with the tenant’s HMAC secret.
Inspect the outcome
Read delivery status, attempt counts and scheduled retries through the history API.
Examples target the local API on port 3000. The current API requires no authentication header.
