Stripe webhook idempotency
Make Stripe webhook handlers safe to retry in Node.
Stripe Webhook Replay Kit is a paid source package for teams that need event ID storage, duplicate-delivery checks, replay locks, and retry-safe handlers without starting from an empty app.
Idempotency paths the kit helps you wire
Duplicate events
Check the incoming Stripe event ID before applying subscription, invoice, or entitlement changes.
Retry-safe handlers
Separate intake from business logic so failed work can be retried without re-verifying stale request bodies.
Replay locks
Use processing state and attempt records to keep manual or scheduled replay from running twice at once.
Buyer workflow

2. Inspect
Run the included smoke checks and read the integration notes before adapting code.
3. Adapt
Map the event storage and handler examples to your database and Stripe event types.
4. Test
Use Stripe test events and duplicate deliveries to prove retries do not double-apply changes.
