Reliable webhook handoff — a self-initiated Rivetfern demonstration using synthetic events.
A Python receiver validates a documented HMAC signature and event schema, records accepted events in SQLite, then processes them with duplicate protection and bounded retries. The repeatable demo covers duplicate events, forged signatures, conflicting payloads, temporary failures and a permanent dead-letter outcome.
Three unique events enter the queue; two create local tasks. No external messages or orders are sent. This is a local engineering sample, not a deployed client system or a Stripe integration.
