March 31, 2026 Karbon API release adds ParentEntity fields to NoteComment webhook notification payloads.

New ParentEntityKey and ParentEntityType Fields in NoteComment Webhook Payloads

Webhook notifications for

JSONCopied!

NoteComment

events now include two new fields —

JSONCopied!

ParentEntityKey

and

JSONCopied!

ParentEntityType

— identifying the entity the comment belongs to, making it possible to retrieve the comment and the context around it with a call to the

JSONCopied!

/v3/Notes

API endpoint.

For example, when receiving the payload:

JSONCopied!
{
  "ResourcePermaKey": "fS9TJ5TrRxZ",
  "ResourceType": "NoteComment",
  "ActionType": "Updated",
  "Timestamp": "2026-03-24T10:25:44Z",
  "ParentEntityKey": "2TTFWz8L5SSt",
  "ParentEntityType": "Note"
}

You can then call

JSONCopied!

GET /v3/Notes/2TTFWz8L5SSt

to retrieve the details of the Note and all comments on the Note.

Field	Type	Description
JSONCopied! `ParentEntityKey`	string	The unique key of the parent entity that the comment belongs to.
JSONCopied! `ParentEntityType`	string	The type of the parent entity (e.g. JSONCopied! `Note` ).
