> Update Coupon. Luma Post V1 Events Coupons Update reference includes SDK V2 and CLI requests, input constraints, response fields, and Deepline cost.

Update Coupon.

<Info>
  Tool ID: `luma_post_v1_events_coupons_update`
</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_events_coupons_update',
  {
    "event_id": "event_123",
    "code": "example"
  },
);

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

### CLI

```bash theme={null}
deepline tools execute luma_post_v1_events_coupons_update --input '{
  "event_id": "event_123",
  "code": "example"
}' --json
```

## Example response

The static output schema is not detailed enough to generate a reliable example. Use `deepline tools get luma_post_v1_events_coupons_update --json` for the complete live contract.
