Creating notifications via the API

Development

I don’t get this to work…

POST https://XXX/notifications
Api-Key:XXX
Api-Username:system
Content-Type:application/json
Accept:application/json

{
    "notification_type":9,
    "user_id": 123,
    "post_number": 1,
    "topic_id": 956,
    "data": {
        "topic_title": "Test",
        "original_post_id": 2222,
        "original_post_type": 1,
        "original_username": "User.Name",
        "revision_number": 1,
        "display_username": "Text"
            }

}

I get as response:


{
  "errors": [
    "Data can't be blank"
  ],
  "error_type": "record_invalid"
}

Formatting error, misunderstanding? Or am I missing something in data?

I can’t really reverse engineer this from the web - Or is this API called somewhere?
