REST API App only token getting 401 unauthorised errors

I need to deploy a pbix file to power I online, inside a workspace, but I cannot use a username and password. Only an app clientID and secret. I’m trying to create an unattending PowerShell script.


There is a delegation role for power I that is Tenant.ReadWrite.All, which by the sounds of things should allow you to do anything within powerBI.


Unfortunately, any attempts at a connection, I can get a bearer token, but any REST API calls after that always returns with a 401 unauthorised status message.


I can share my code tomorrow (when I’m on my work pc), but is it actually possible to do what I’m attempting. Any examples or prebuilt PowerShell powerBI modules always needs a username and password for authentication.
