Confluence Cloud API, creating secure webhook

Hi Community,

Im working on a solution to listen to events on Confluence pages, like, page_created, page_updated etc.

So far, have registered successfully a webhook using Rest API: POST ‘https://domain.atlassian.net/wiki/rest/webhooks/1.0/webhook
The above webhook fires events to our route with payload.

Im unable to find out how to secure the webhook communication to our route.

So far, I have been told:
The API you’re using is an unsupported internal API. You can use it to register and de-register webhooks, but it doesn’t provide a mechanism to secure them.

Question:
is there a way to secure the confluence webhook? if not, is there any other way to listen to the events on confluence pages?

Best Regards
Kamran
