'Service Principal Authentication to Microsoft Dynamics 365 API issue

For the life of me I cannot figure this out. I am trying to write a PowerShell Script that will get a list of solutions in a tenant

The Url to do this is as following: https://(MyCRM).dynamics.com/api/data/v9.x/solutions

Service principal items I have are: ClientId, ApplicationId, ClientSecret

In my case I am using Invoke-WebRequest

How do I build the Authentication part of the Invoke-WebRequest, to successfully get the request through?

so someone pointed me to a solution :) basically its a two step process:

  1. you get the access token from https://login.microsoftonline.com
  2. than you use the token in your authorisation header for any calls you do to the server
