Restful Notification, PV Data every 5 minutes

I have to send my solar photovoltaic plant’s real time power and total energy yield data every 5 minutes to a service. I have the API for it but i am not sure how to do it. I was told to us the Restful notification.
I have all the data. I still use it for energy board etc.

First i wrote this in my configuration.yaml


But i dont know how the automation should look like.

Pherhaps someone has an idea.

Thank you
