Unfortunatelly, no. You always have to poll the API to check the status
of the operation.
Just for info, we have new Python SDK version 4. Python SDK version
3 will be removed someday in future. So you would have to migrate your
scripts, so maybe better to write it in version 4 now, then rewrite it
And also, if you don't know Python, but you know Ansible, you can use
Ansible VMs module.
