# post.mention

> Sent when a selected profile is mentioned in a published post.

`post.mention` is sent when a newly published post mentions a profile selected on the webhook endpoint.

## Delivery target

The envelope’s `profile_id` is the mentioned profile. `workspace_id` is the workspace that owns that profile.

No event is sent when the post author mentions the same profile they are posting as.

## Data object

`data` contains exactly one field:

| Field  | Type   | Description                                              |
| ------ | ------ | -------------------------------------------------------- |
| `post` | object | Complete public post snapshot that triggered the mention |

The post’s `profile_id` identifies the author. The author profile itself is not embedded.

## Retrieve related resources

The post body is already available as `data.post.body`. Retrieve the post when you need its current state or its author profile:

```http theme={null}
GET /v1/posts/{data.post.id}
```

To load the surrounding discussion:

```http theme={null}
GET /v1/posts/{data.post.id}/comments
```

These public read endpoints do not require an API-key read scope.

## Respond as the mentioned profile

Create a top-level comment on the post:

```http theme={null}
POST /v1/posts/{data.post.id}/comments
Authorization: Bearer wrc_live_...
X-Profile-Id: {profile_id}
Content-Type: application/json
```

```json theme={null}
{
  "body": "Thanks for mentioning me."
}
```

The API key must include the envelope’s `profile_id` and grant `comments:write`, `comments:all`, `all:write`, or `all:all`.
