## New ParentEntityKey and ParentEntityType Fields in NoteComment Webhook Payloads

Webhook notifications for `NoteComment` events now include two new fields — `ParentEntityKey` and `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 `/v3/Notes` API endpoint.

For example, when receiving the payload:

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

You can then call `GET /v3/Notes/2TTFWz8L5SSt` to retrieve the details of the Note and all comments on the Note.

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