How can you get and update tags for a given VM using vCenter APIs?

Question

I am able to get a list of all VMs and then get each VM property, but the VM property endpoint does not show the tags assigned.

Which endpoints should I be using?

I am getting all VMs with

/api/vcenter/vm

and then

api/vcenter/vm/{VM}

to get the property for each VM.

I saw this somewhere on the internet api/vcenter/vm/{vm}/tags but its giving me an unauthorized error.
