How to get a proper bearer token using Postman for a Service Principal

[Collins_Rowan]

I was previously using the .net sdk and pulling the token out of there and using it in Postman.

I'm trying to get a proper bearer token using Postman for Power Bi.

I'm hitting "GET https://login.microsoftonline.com/:tenantId/oauth2/token"

with my tenantId being inserted by Postman

with my client_id, client_secret,
grant_type = client_credentials
scope = 'https://analysis.windows.net/powerbi/api/.default'

But all of the calls now return a 403 Forbidden with the token returned.

I encountered the same issue, and just solved it myself. read it here: Solved: Dynamic Token refresh for PBI Admin API calls not ... - Microsoft Fabric Community
