When creating the webhook, you should provide a
url for receiving POST messages, and an array of
events in the request body.
You may specify specific booking lifecycle events you wish to subscribe to, or you can pass the
booking event to trigger the POST payload message whenever any of the supported booking lifecycle events occurs. Learn more about events
Make sure that you pass the full URL. For security reasons, we only accept HTTPS URLs.
