To run Python code in an n8n Code node, write standard library-only scripts using _input.all(), _input.first(), or _input.item to access data, then return a list of {"json": ...} objects for valid output.

No, you cannot use external Python libraries inside n8n. Python execution in Code nodes is limited to the standard library only, meaning complex transformations requiring external packages are not supported.

To handle webhook payloads in n8n Python Code nodes, access incoming data via the body located in _json, navigating nested structures as needed before processing and returning the required list of json objects.

Your n8n Python Code node returns an error typically due to KeyError, IndexError, missing returns, or wrong output formats. Python scripts must return a list of {"json": ...} objects and handle data access safely.

You should use JavaScript instead of Python in n8n Code nodes for HTTP requests, date handling, or complex transformations, as JavaScript handles these operations more natively without standard library limitations.

The best way to process batch data with Python in n8n is using _input.all() to read all items, applying your standard library transformations, and returning a properly formatted list of {"json": ...} objects.
