| `campaign_id`    | string or SelectItem | Yes      | -       | Snapchat campaign ID to update.

| `update_payload` | object or string     | Yes      | -       | Campaign fields to update as a JSON object; only the fields you include are changed (each key becomes a JSON-Patch add operation, and a null value removes an optional attribute).

Prefer the dedicated operations for plain changes: snapchat\_ads\_update\_campaign\_status, snapchat\_ads\_rename\_campaign, snapchat\_ads\_update\_campaign\_budget. Example: \{"end\_time": "2026-09-30T00:00:00Z", "daily\_budget\_micro": 50000000} |
