API: get custom properties of a machine

Hi guys

I need to get the custom properties of a machine over the vRA rest api. We currently have vRA 7.3 in place.

The strange thing they seems not to be available on the machine resource itself e.g.

https://{{vra-fqdn}}/catalog-service/api/consumer/resources/{id}

or

https://{{vra-fqdn}}/catalog-service/api/consumer/resourceViews/{id}

I searched now hours to find a way in the REST API doc of vRealize Automation 7.3. But without any success.

Use case I:

I have to get the custom property Snapshot.Policy.Limit value of a machine.

Use case II:

I have to get all the custom properties of a machine.

I hope you can help me with this issue. Thanks a lot in advance.

BR,

Simon
