Source: Stack Overflow #55734473 (accepted answer, 3 votes): the asker called the Calendly hooks endpoint expecting scheduled appointment data and got only webhook subscription data back. The accepted answer explains the confusion: a webhook is a listener, not a data endpoint. You register the subscription once, and Calendly then POSTs the appointment payload to your webhook URL whenever an invitee books or cancels. To list existing meetings, use the regular API instead.
