I don't see any way to retrieve the file ID, ie, "id:ABAASD123422" from a session_finish call, ie what is returned is the path of the uploaded file, not an id.
I can use the alpha calls (getmetadata) supplying the "path" but of course these are alpha calls.
Any way to force the V2 call of session finish to return id's vrs literal names?
V2 -- 'user' http interface
