You can register an event on one / multiple nodes depending on the event.

The API to use is


        "eventType": "",
        "level": "error",
        "message": "This is a test",
        "nodes": [
        "nodeType": "",
        "parts": {
          "part1": "part1value"
        "startTime": "2020-01-09T14:34:00Z",
        "endTime": null,
        "data": {}

The "nodes" section is the place where you can reference one to multiple nodes that are affected by the event.

"endTime" can be null if the event does not have a duration.

"data" can be empty, but can also contain any custom JSON object
