Create Or Invite User To Veracity Using Service API

I want to create a user to my service using the rest api

  • https://api.veracity.com/veracity/services/v3

At first I have collected token using Client Credentials grant Sign in to your account

After that I posted service api to create user.
https://api.veracity.com/veracity/services/v3/this/user

But I am getting 401 unauthorized.

What is the way to create user in Veracity using Rest Api and Client Credential flow.

Are other endpoints working?

Have you included the Ocp-Apim-Subscription-Key header with API subscription key for your application?
