Issue with MS Fabric REST API : PowerBINotAuthorizedException

[akanane]

Hello everyone,

I am encountering issues while trying to access the admin scope of the Fabric REST API. Here's the steps that I followed:

- Created an app registration in Azure AD

- Set up a security group and assigned the roles Fabric Administrator (and Power Platform Administrator)

- Added the service principal to this security group

- Added API permissions Tenant.Read.All & Tenant.ReadWrite.All

- Created a secret & used it to get token (successful and with the right scopes):

However, i couldn't list all the workspaces (PowerBINotAuthorizedException)

Notes:

- both scopes powerbi & fabric don't work

- when i authentify with an admin account using MSAL's PublicClientApplication, i can list all the workspaces

I've thoroughly checked the setup, but I'm unable to identify the issue. Any guidance or insights would be greatly appreciated.

Thank you

Hi. Is this still a limitation? I see conflicting information in the docs. Below links suggest that we can use Entra ID app to work with Fabric REST APIs:

https://learn.microsoft.com/en-us/rest/api/fabric/articles/get-started/fabric-api-quickstart

https://learn.microsoft.com/en-us/rest/api/fabric/articles/get-started/create-entra-app

I followed these steps but still can't get it to work.
