Smarts EDAA device creation payload

Hello,

I'm starting to do some automation using the Smarts 9.4 EDAA. According to the EDAA Programmer Guide, to create a device, you simply POST a device payload to /types/$device/instances. However, the only information I can find about the payload is that "Name" is required. I've tried posting various payloads to the server, but always get "DMT createInstance Name not specified" which goes back to "Name" being required. Does anybody know what the payload is supposed to look like or know of a document that has this information?

Thanks.
