I am also looking for a solution to this. The path suggested by @Retired_mod does not work! When I run the proposed az cli, this is what I get:
```
$> az databricks workspace show --resource-group $my_rg --name $my_ws --query 'id'
"/subscriptions/64e..<my_tenant_id>/resourceGroups/<my_rg>/providers/Microsoft.Databricks/workspaces/<my_ws>"
```
This is not the account ID that is needed for the account API. So this is not a solution. Since terraform and REST API are directly aligned with the cli, the result is the same. So at present there is no solution to this. Unless anyone has any other suggestions?
