How to get data from a database through an API connection

Hello, I am trying to obtain data from Xedule into powerBI and I have a URL link and the key for my API connection (I can't share them because of privacy), however I don't know how to combine these two to retrieve my dataset. I tried to use Odatafeed but it shows the error: "A web API key can only be specified when a web API key name is provided".

When I enter the URL link in google it shows me a file similar to a swagger editor file. Can anybody help me? 🙂
