Write your expression in the parameter, or select **Open expression editor** to open the expressions editor. You can browse the available data in the **Variable selector**. All expressions have the format `{{ your expression here }}`.\n\n### Example: Get data from webhook body\n\nIf your webhook data looks like this:\n\n```json\n[\n {\n \"headers\": {\n \"host\": \"n8n.instance.address\",\n ...\n },\n \"params\": {},\n \"query\": {},\n \"body\": {\n \"name\": \"Jim\",\n \"age\": 30,\n \"city\": \"New York\"\n }\n }\n]\n```\n\nYou can use the following expression to get the value of `city`:\n\n```js\n{{$json.body.city}}\n```\n\nThis expression accesses the incoming JSON-formatted data using n8n's custom `$json` variable and finds the value of `city` (in this example, \"New York\").", "codeSnippet": "{{$json.body.city}}" }, { "role": "assistant", "type": "message", "text": "Did this answer solve your question?", "quickReplies": [ { "text": "Yes, thanks", "type": "all-good", "isFeedback": true }, { "text": "No, I am still stuck", "type": "still-stuck", "isFeedback": true } ] } ] }
