# Attio: Create Comment

> Post a comment in Attio on a record, a list entry, or an existing comment thread. Includes inputs, outputs, SDK V2 examples, and Deepline cost.

Post a comment in Attio on a record, a list entry, or an existing comment thread.

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

## 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(
  'attio_create_comment',
  {
    "format": "plaintext",
    "content": "Example message",
    "author": {
      "type": "workspace-member",
      "id": "id_123"
    },
    "thread_id": "thread_123"
  },
);

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

### CLI

```bash theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
deepline tools execute attio_create_comment --input '{
  "format": "plaintext",
  "content": "Example message",
  "author": {
    "type": "workspace-member",
    "id": "id_123"
  },
  "thread_id": "thread_123"
}' --json
```

## Example response

The static output schema lacks the details for a reliable example. Use `deepline describe attio_create_comment --json` for the complete live contract.

## Input reference

Create a comment on an existing thread, record, or list entry.
