I guess the question is more an underlying REST design principle. This
article describes
the idea quite well.

Short: you do a POST to a generic resource /things. The server
responds with a 201 Created response telling you the Location where it
has generated the actual thing, like /things/123. Then you can use
this Location as the subject.

Does this help?
