## 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(
  'apollo_bulk_update_contacts',
  {
    "contacts": [
      {
        "contact_id": "contact_123"
      }
    ]
  },
);

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

### CLI

```bash theme={null}
deepline tools execute apollo_bulk_update_contacts --input '{
  "contacts": [
    {
      "contact_id": "contact_123"
    }
  ]
}' --json
```

## Example response
