Replay protection stops the same webhook event from triggering automation multiple times.
Webhook Replay Protection prevents duplicate processing when events are retried or delivered more than once. This is common with network issues, queue retries, or provider event systems. Without replay protection, a single “reply received” event can trigger multiple follow-ups, labels, or CRM writes. A solid solution uses idempotency keys, event IDs, and time windows to ignore duplicates safely. For Gmailo-like platforms, replay protection is a reliability feature that quietly prevents embarrassing automation mistakes.
