## 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(
  'affinity_v2_persons_person_id_fields_field_id_post',
  {
    "personId": 123,
    "fieldId": "field_123",
    "value": {
      "type": "company-multi",
      "data": [
        {
          "id": 123
        }
      ]
    }
  },
);

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

### CLI

```bash theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
deepline tools execute affinity_v2_persons_person_id_fields_field_id_post --input '{
  "personId": 123,
  "fieldId": "field_123",
  "value": {
    "type": "company-multi",
    "data": [
      {
        "id": 123
      }
    ]
  }
}' --json
```
