Generating Authorization: Bearer token for calling Power BI Rest API

[innocence84]

Hi,

When I  called a Power BI Rest API via the try it page in the web site (https://learn.microsoft.com/en-us/rest/api/power-bi/admin/datasets-get-datasets-as-admin ),
Microsoft is generating a token that starts with: 

Authorization: Bearer ey...

 I need to call Power BI Rest APIs from a dataset/dataflow. For that reason I need to generate Authorization: Bearer token. 
Which API should I call for generating this token?

Thanks

Thank you.

We want to call the Power BI rest API from a Power BI data flow. So it's not an embedded app. We also want to call via Azure Active directory app registration instead of user/password. How can we call Power BI rest API from a dataflow by using app registration?
