# Luma: Post V1 Calendars Contact Tags Apply

> Apply a tag to existing calendar contacts. Includes SDK V2 guidance, input constraints, response fields, and Deepline credit cost.

Apply a tag to existing calendar contacts.

<Info>
  Tool ID: `luma_post_v1_calendars_contact_tags_apply`
</Info>

## Run this action

Use the TypeScript SDK for a single call. Put `ctx.tools.execute(...)` inside a Play when the call should be durable, scheduled, or run across a CSV.

```ts theme={null}
import { Deepline } from 'deepline';

const deepline = await Deepline.connect();
const result = await deepline.tools.execute(
  'luma_post_v1_calendars_contact_tags_apply',
  {
    "tag": "example"
  },
);

console.log(result.toolResponse.raw);
```

### CLI

```bash theme={null}
deepline tools execute luma_post_v1_calendars_contact_tags_apply --input '{
  "tag": "example"
}' --json
```

## Example response

The SDK exposes this shape at `result.toolResponse.raw`. Values below are representative.

```json theme={null}
{
  "data": {
    "applied_count": 123,
    "skipped_count": 123
  }
}
```

Use `deepline tools get luma_post_v1_calendars_contact_tags_apply --json` for the latest machine-readable contract.
