Having trouble connecting to Power BI with the API Key


I’m new here, just trying to work out how to connect the API to Power BI.

I’ve gone to new source


in Power Bi then put in the web url as basic


it then came up with the API key spot and a drop down of the above url.

I put in my API key but it then said “A web API key can only be specified when a web API key name is provided.”

I tried to add a web API key name but I don’t think I can, all I could see was the revoke button on the API key page. I’m only using a personal account at the moment. Not sure if I am doing something wrong.
