How to manage reservations?

[kelnerrr]

Hi,

is there any way to to manage Reservations with AzureRMR?
I'm thinking about getting the list of Reservation Orders and then the list of all Reservations.

I was trying to get the resource with:

az <- get_azure_login()
az_resource$new(
  token = az$token$credentials$access_token,
  subscription = sub_id, 
  id = "/providers/microsoft.capacity/reservationOrders/{guid}/"
)

When I added the required subscription parameter I got this:

Error: No API versions found
In addition: Warning message:
No stable API versions found, falling back to the latest preview version

That would be great to have a possibility to manage Reservations.
What I need now would be to only assign permissions for people/groups to the Reservation Orders.

Have you tried it using the recommended approach?

az <- get_azure_login()
az$
  get_subscription(...)$
  get_resource_group("resgroupname")$
  create_resource(
    type="microsoft.capacity/reservationOrders",
    name="whatever"
  )

Reservations are a strange thing and are not under any resource group.
They are billed on a specific subscription but may be used by other subscriptions as well. So probably they do not even belong to a subscription (not counting for billing purposes).
Unfortunately, I do not know how the reservations look under the hood.

I found a confirmation that a reservation is not a subscription's resource.

The reservation lifecycle is independent of an Azure subscription, so the reservation isn't a resource under the Azure subscription. Instead, it's a tenant-level resource with its own Azure RBAC permission separate from subscriptions.

Would there be any way to manage such a resource with AzureRMR?
