Rest Order Api Put - Order Properties

[jobo]

Hi,
I want to update via Rest Api the order properties, which customers have made. I use the following json theme. But unfortunately nothing happens... Can someone help me?

{
  "order": {
    "line_items": {
      "0": {
        "properties": {
          "0": {
            "value": "test"
          }
        }
      }
    },
    "note": "Only a test"
  }
}
