Who Me Too'd this topic

I have Panorama managing my firewalls. I would like to leverage Postman to make API POSTS to Panorama for new security policies. 

Can someone provide an example of a filled-out body with bogus data to show me how the API wants it?

I'm particularily getting stuck on the first part of the body.. I have a device group called "firewalls" and the device is named "firewall1"

{

            "entry": {

                        "@name": "testrule",

                        "target": {

                              "devices": {

                                       "entry": [

                                             null

                                        ]

                              },
