# User Type Targeting

Use user type targeting to control whether a line targets only addressable users or also includes non-addressable users. On non-addressable supply where third-party cookies or device IDs are unavailable (for example, Safari ITP 2.0), Yahoo DSP leverages contextual-based signals to apply demographic, audience and frequency capping logic to expand audience reach.

## Endpoint

```plaintext
/traffic/lines/{id}/targeting
```

Use the following HTTP methods.

- Use the `GET` method to retrieve the user type configured for the specified line.
- Use the `POST` method to apply the user type targeting to a specified line.

Required and Supported Parameters

| Parameter | Type | Description | Data Type | Required |
| --- | --- | --- | --- | --- |
| `id` | path | The line ID. | integer | Yes |
| `targetOnlyAddressableUsers` | body | Specifies whether the line targets only addressable users or includes non-addressable users. If `true`, the line will only target addressable users. If `false`, the line will expand targeting to non-addressable users by applying demographic, audience, and frequency capping through contextual-based signals. | Boolean | Yes |
