Python script to load REST API output

We have an application that just made REST API available. 

We want to extract data from here and make nice dashboards in PowerBI. So the final goal for this is to be realtime. 

Now the token for the REST API expires every 60 minutes. So we made a python script that fetches the token. The final output is a json file. How can i feed this output directly in powerbi instead of saving the file to my local workstation?
