Possible to run a web hook on ticket raised event?

I think that my request might be answered by:

But I wasn’t clear. To verify - is it not possible to call a web hook when the Ticket is Raised? I have set up a web hook that works when using Postman or the built-in test tool in the Workflow Automator interface but it doesn’t seem to call the web hook when creating a new ticket.

Thanks so much for any help.
