ADMIN Rest API request using Service Principal

[Anonymous]

Hi all, 

I am trying to use ADMIN REST API for Power BI (e.g., GetGroupsAsAdmin) using a Service Principal (Read-Only). 

I have follow the MS documentation for this process: 

1. Create App in Azure (Without any PBI Admin-consent credential)

2. Add the App into a Secure Group in Azure

3. Enable the Service Principal in Power BI and add the Secure Group as an specific group

4. Add the App as a member of the workspaces in Power BI Service

Then I generate the access token in PowerShell and try to pull out data from REST API using Anonynous connection in Power BI Desktop.

Yet I was getting a forbidden access message...

Then we allow the Delegated Permission (Tenant.ReadAll) but message just changed to "Credential provided are not valid"

Does anyone know what could be happening?

Many thanks

1. Allow service principals to use Power BI APIs
2. Allow service principals to use read-only Power BI admin API
