I am receiving some data via Webhook but the information is grouped

“body”: {

}

I need the data to be returned this way in order to use the data

I looked here for a way to remove the data via an array using a function, but unfortunately I can’t make it work

can you help me? Thank you very much

Hey @Rodrigo_Barbosa, this looks like the data is simply stringified. Would you be able to parse it using JSON.parse()? Here’s an example where I am using the Function Item node to do so:

Example Workflow 
{
  "nodes": [
    {
      "parameters": {},
      "name": "Start",
      "type": "n8n-nodes-base.start",
      "typeVersion": 1,
      "position": [
        240,
        300
      ]
    },
    {
      "parameters": {
        "functionCode": "return [{\n  json: {\n    body: {\n      data: \"{\\\"retorno\\\": \\\"...\\\"}\"\n    }\n  }\n}]"
      },
      "name": "Set Example Data",
      "type": "n8n-nodes-base.function",
      "typeVersion": 1,
      "position": [
        460,
        300
      ]
    },
    {
      "parameters": {
        "functionCode": "item.data = JSON.parse(item.body.data);\n\nreturn item;"
      },
      "name": "Parse JSON",
      "type": "n8n-nodes-base.functionItem",
      "typeVersion": 1,
      "position": [
        680,
        300
      ]
    }
  ],
  "connections": {
    "Start": {
      "main": [
        [
          {
            "node": "Set Example Data",
            "type": "main",
            "index": 0
          }
        ]
      ]
    },
    "Set Example Data": {
      "main": [
        [
          {
            "node": "Parse JSON",
            "type": "main",
            "index": 0
          }
        ]
      ]
    }
  }
}

If that’s not what you’re looking for, could you share your code snippets in preformatted blocks? You can either use this button:

Or manually put three backticks ``` above and below your code snippets. This would prevent the forum from applying formatting to your code which makes it really hard to use it.

Thank you!
