> Tool ID: `attio_create_attribute`

## 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_attribute',
  {
    "target": "objects",
    "identifier": "example_123",
    "title": "VP of Engineering",
    "api_slug": "example",
    "type": "text"
  },
);

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

### CLI

```bash theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
deepline tools execute attio_create_attribute --input '{
  "target": "objects",
  "identifier": "example_123",
  "title": "VP of Engineering",
  "api_slug": "example",
  "type": "text"
}' --json
```

## Example response

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