Can I use external Python libraries like Pandas or Requests in n8n?

No, n8n Code nodes are limited to the Python standard library. For HTTP requests, use the n8n HTTP Request node or JavaScript helpers.

How do I access webhook data in an n8n Python node?

Webhook data is typically nested under the 'body' property. Use _json['body'] or _json.get('body', {}) to access it safely.

Should I use JavaScript or Python in n8n?

JavaScript is recommended for 95% of use cases due to better helper support; use Python only when you need specific standard library functions or have a strong syntax preference.

What is the difference between Python (Beta) and Python (Native) in n8n?

Python (Beta) includes n8n-specific helpers like _input and _now, whereas Python (Native) uses a more restricted pure Python environment with _items.

What is the mandatory return format for n8n Python nodes?

You must always return a list of dictionaries where each dictionary contains a 'json' key, for example: return [{'json': {'data': 'value'}}].
