Exactly-once webhook side effects.
No duplicate charges. No double emails. No “we’ll fix it later” logic.
WebhookGate guarantees your webhook handlers execute once — and only once.
Webhooks are unreliable by design.
Stripe, GitHub, Shopify, and others will retry events.
- customers charged twice
- emails sent twice
- state mutated twice
- emergency hotfixes at 2am
Idempotency sounds simple — until it isn’t.
WebhookGate enforces exactly-once execution.
It sits between the webhook sender and your handler and guarantees:
- each event is processed once
- retries are safely ignored
- side effects never repeat
No race conditions. No fragile ad-hoc guards. No guesswork.
How it works (high-level)
WebhookGate provides durable intake + execution locking, so your business logic never runs twice — even under retries, crashes, or concurrency.
You keep your existing handlers. WebhookGate handles the hard parts.
Who it’s for
WebhookGate is for teams who:
- handle money, emails, or irreversible actions
- rely on third-party webhooks
- are tired of writing bespoke idempotency logic
- want correctness > cleverness
If duplicate side effects would be a serious incident for you, this is for you.
Pilot program
We’re onboarding 5–10 teams into a private pilot.
This is not a free beta. This is paid, serious infrastructure.
