SharePoint 2013 REST Create "document set" folder

Hi,

Is there a way in rest api model to create a "document set" folder into a Library?

I have already created a folder through this code :

body: { '__metadata': { 'type': 'SP.Folder' }, 'Name': 'New name' }

Do i need to use another namespace ? Or do i add new properties into the body section ?

Regards.
