## 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(
  'lemlist_post_sequences_sequenceid_steps_stepid_ab_test_winner',
  {
    "sequenceId": "sequence_123",
    "stepId": "step_123",
    "variant": "A"
  },
);

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

### CLI

```bash theme={null}
deepline tools execute lemlist_post_sequences_sequenceid_steps_stepid_ab_test_winner --input '{
  "sequenceId": "sequence_123",
  "stepId": "step_123",
  "variant": "A"
}' --json
```

## Example response

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

```json theme={null}
{
  "data": {
    "stepId": "step_123",
    "abTest": "A"
  }
}
```

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