vRealize Automatio-Reservation API Unathorized

Have been working on some vRA APIs for Reservation creation. I am trying to see all business groups and compute resources using these urls

https://$host/identity/api/tenants/qe/subtenants

https://$host/reservation-service/api/data-service/schema/Infrastructure.Reservation.Virtual.vSphere/default/computeResource/values

Keep running into issues with output

{

    "errors": [

        {

            "code": 10108,

            "message": "Invalid data access API use.",

            "systemMessage": "HTTP/1.1 401 Unauthorized : ",

            "moreInfoUrl": null

        }

    ]

}

I have all Tenant Admin, Infra Admin, and Fabric Admin access. Anyone using Reservation API ?
