Alternative CreateThing commands

If you want to copy an Existing policy instead of creating a new one by yourself or reference an existing Policy, you can adjust the CreateThing command like demonstrated in the following examples.

CreateThing with copied Policy by Policy ID

Creates a new Thing with ID com.acme:xdk_53 with a Policy copied from the Policy with ID com.acme:the_policy_id_to_copy.

{
  "topic": "com.acme/xdk_53/things/twin/commands/create",
  "headers": {},
  "path": "/",
  "value": {
    "__schemaVersion": 2,
    "__lifecycle": "ACTIVE",
    "_revision": 1,
    "_namespace": "com.acme",
    "thingId": "com.acme:xdk_53",
    "policyId": "com.acme:the_policy_id",
    "_copyPolicyFrom": "com:acme:the_policy_id_to_copy"
  }
}

CreateThing with copied Policy by Thing reference

Creates a new Thing with ID com.acme:xdk_53 with a Policy copied from a Thing with ID com.acme:xdk_52.

{
  "topic": "com.acme/xdk_53/things/twin/commands/create",
  "headers": {},
  "path": "/",

  }
}
