# Webhook Event

A webhook event is sent when an entity in our system changes state. Select an
event type below to see the exact payload it delivers. Webhook events contain
metadata about the change (entity ID, event type, event ID, and event
timestamp) but do not include the actual entity data.

To get the current state of the entity that triggered the webhook, fetch it
from the corresponding GET endpoint using the `entityId`. We send webhooks
asynchronously, so by fetching the entity data separately, you always have the
most up-to-date information from a single source of truth.
