OpenText REST - Get Additional Node Attributes

Sam Foster

I have created an "Additional Node Attribute" within Content Server and set a value for this on some of my documents. 

Is it possible to get the value set for this field for a given document via the API? - The field does not seem to be returned by "/api/v1/nodes/{id}", "/api/v1/nodes/{id}/properties" or "forms/nodes/properties/general?id=" ... 

Any pointers would be greatly appreciated!
