Subscribe to an event type Changes data

POST/hooks

Subscribes a callback address to one event type, for every event of the workspace or one of them. The answer's Location header is the address to DELETE to unsubscribe. Each delivery is a plain JSON body: id, type, timestamp and what happened. A callback that answers 410 Gone is unsubscribed, and every subscription goes when its key is revoked or expires. Needs webhooks:write (keys made before 15 October 2026: webhooks:read) and the scopes of what the type delivers.

Parameters

header

Idempotency-Keystring
A key of your own, such as a UUID, so a retry after a lost connection is answered with the first answer instead of doing it twice. Kept 24 hours.

Body NewHookWithType

The callback, the event type and optionally the event.

urlstringrequired
The https address to call with each event.
eventstringrequired
The event type to receive.
One of: attendee.registered, attendee.updated, attendee.cancelled, attendee.erased, order.paid, checkin.created, feedback.given, lead.captured, certificate.issued, content.published, stay.requested, stay.assigned, stay.changed, stay.cancelled, member.joined, member.left, travel.changed, claim.submitted, claim.approved, claim.paid, shift.signed_up, shift.dropped
eventIdstring (uuid)
Only this event of the workspace; every event when absent.
