Note is null after acknowledging an alert

aycode

When I use the Orion API:

/SolarWinds/InformationService/v3/Json/Invoke/Orion.AlertActive/Acknowledge

{
 "alertObjectIds" = "1234",
 notes = "this has been acknowledged"
}

the note is always null on the Orion.AlertActive:

{
  "AlertActiveID": 1234,
  "AcknowledgedBy": "theuser",
  "AcknowledgedDateTime": "2025-01-30T13:13:15.527Z",
  "AcknowledgedNote": null,
  "NumberOfNotes": null,
}

instead, it's stored in the linked Orion.AlertActive.AlertObjects.AlertNote:

{
  "AlertActiveID": 0001,
  "AcknowledgedBy": "theuser",
  "AcknowledgedDateTime": "2025-01-30T13:13:15.527Z",
  "AcknowledgedNote": null,
  "NumberOfNotes": null,
  "AlertObjectID": 1234,
  "AlertNote": "this has been acknowledged"
}

Is this how it works? Why is the acknowledgement null in Orion.AlertActive?

Also, is there a way to overwrite the note? It just accumulates lines every time it's acknowledged with a note:

this has been acknowledged\r\n
this has been acknowledged\r\n
this has been acknowledged\r\n
this has been acknowledged\r\n
