VERITYAuth & billing module
Signed, retried, replay-safe outbound webhooks with a delivery log your buyers can read.
Relay is the outbound webhook service we run in production, packaged. HMAC signatures with key rotation, exponential retry with jitter, per-endpoint circuit breaking, and a delivery log with the full request and response of every attempt.
Postgres is the only dependency. It runs as a sidecar container or as a library inside your existing Node process.
Four engineers who got tired of rewriting the same queue, webhook, and auth plumbing on every contract. Everything we sell runs in our own production.
Every purchase generates a license code you can verify from your own application through the purchase-code API.
Overlapping keys meant we rotated signing secrets across 400 endpoints without a single failed delivery. Worth it for that alone.
No dashboard beyond the delivery log, which is fine by me. Would like a Prometheus endpoint.
