      "parameters": {},
      "name": "Start",
      "type": "n8n-nodes-base.start",
      "typeVersion": 1,
      "position": [
        250,
        300
      ]
    },
    {
      "parameters": {
        "path": "235cdfe3-ddba-4567-b8c7-fb9aff056d5b",
        "options": {}
      },
      "name": "Webhook",
      "type": "n8n-nodes-base.webhook",
      "typeVersion": 1,
      "position": [
        450,
        450
      ],
      "webhookId": "235cdfe3-ddba-4567-b8c7-fb9aff056d5b"
    }
  ],
  "connections": {}
}
