Power Bi Rest Api App Endpoints

I am trying to interact with an App on a workspace using a service principal. The documentation states that service principals are not allowed. https://learn.microsoft.com/en-us/rest/api/power-bi/app...

The service principal is merely polling from an app. There is nothing that could go pear shaped because the only authorization bit you can assign is read access to a service principal. Users, who are viewing the app's reports in a different form on a website, have their own RLS, permissions, and identity management with auditing invovled. I am not interested in leaking a credential that could risk PHI loss. 

I'm trying to understand why a service principal cannot access a domain's endpoints. I have found, 

https://ideas.fabric.microsoft.com/ideas/idea/?ideaid=7f91faef-43f4-45b4-bbb6-80ca1fd8a627, which means we cannot embed the app. Our options are pretty limited unless we forgo the app and create something custom on our end, to forgo a service principal, which goes against a lot of the domains on the power bi rest api.

Hi jmoore11 , If you have access to fabric trial / fabric capacity and an admin user. You can run this piece of code in your fabric notebook and store it in a lakehouse and further clean the data to get the list of reports mapped to their respective apps.

No Service principal is needed and credentials are not exposed in this approach but the user who is running this code should be a Power BI Admin . The App ID will be present in web url column of the json response. I have used sempy library which is an official library released by Microsoft

import sempy.fabric as fabric

client = fabric.FabricRestClient()
reports_url = "v1.0/myorg/admin/reports?$top=5000"
reports_json = client.get(reports_url).json()

apps_url = "v1.0/myorg/admin/apps?$top=5000"
apps_json = client.get(apps_url).json()

 

Thanks,

Jai
