# Unipile: Send Message In Chat

> Send a text message in an existing LinkedIn, WhatsApp or other connected chat, by its chat ID. Includes inputs, outputs, SDK V2 examples, and Deepline cost.

Send a text message in an existing LinkedIn, WhatsApp or other connected chat, by its chat ID.

> [!NOTE]
>
> Tool ID: `unipile_send_message_in_chat`

## Run this action

Use the TypeScript SDK for one call. Use `ctx.tools.execute(...)` inside a Play for durable calls, scheduled calls, or CSV processing.

```ts theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
import { Deepline } from 'deepline';

const deepline = await Deepline.connect();
const result = await deepline.tools.execute(
  'unipile_send_message_in_chat',
  {
    "chat_id": "chat_123",
    "text": "example"
  },
);

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

### CLI

```bash theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
deepline tools execute unipile_send_message_in_chat --input '{
  "chat_id": "chat_123",
  "text": "example"
}' --json
```

## Example response

The SDK returns this shape at `result.toolResponse.raw`. The example values illustrate the response.

```json theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
{
  "data": {
    "object": "MessageSent",
    "message_id": "message_123"
  }
}
```

Use `deepline describe unipile_send_message_in_chat --json` for the latest machine-readable contract.
