Podium Webhook Reliability
Hardens Podium webhook receivers against forged events, replay attacks, duplicate deliveries, and silent data loss.
Podium Webhook Reliability provides production-tested patterns for building secure, fault-tolerant Podium webhook receivers. It prevents common integration pitfalls such as unverified payloads, duplicate execution during Podium's 24-hour retry window, timing attacks on HMAC validation, and out-of-order batch deliveries. By implementing constant-time signature verification, Redis-backed atomic deduplication, timestamp-bounded replay windows, and dead-letter queues (DLQ), this skill ensures mission-critical conversation, review, and webchat events are processed reliably and securely.
