Webhook

A callback URL that one system pings when an event occurs in another system.

A webhook is a callback mechanism: system A holds a URL provided by system B, and pings that URL when a specific event occurs (a new booking, a payment captured, a check-in completed). Webhooks enable real-time integration without polling, which is the foundation of low-latency PMS-to-guest-journey-platform sync. Vendors that only support polling APIs (no webhooks) introduce minutes of latency that compound into operational issues.
