How to associate a tag using vAPI

Hi guys,

I'm trying to associate a vCenter tag to some VMs using the vAPI in orchestrator.

I've found the "com_vmware_cis_tagging_tag_association" object that has the attach method. The input parametes to the method are tag_id (string) and object_id (com_vmware_vapi_std_dynamic_id).

I've found a way to get the tag_id but I was not able to get the object_id. How can I get an object of the type "com_vmware_vapi_std_dynamic_id" from a VcVirtualMachine?

Thanks.
