The example JSON body is

{
  "group_perms": {
    "property1": "admin",
    "property2": "admin"
  },
  "user_perms": {
    "property1": "admin",
    "property2": "admin"
  }
}

What does this mean? What are property1 and property2?

A customer is trying to use this API and can't figure it out; neither can I from the docs!
