Update friendly name using Automation WebHook

Hello, I am trying to create and automation from where I can change Entity Friendly name. I think Webhook is one good option for me. But not sure if I can send any parameter in it.

And how to call it! Even that is one big challenge at the moment. So any way someone can suggest how can I do?

Guys automation UI is good, but really difficult to understand for the first time.

Thank you!
