Python in n8n Code nodes supports the standard library only, including json, datetime, re, base64, hashlib, and math. You cannot install or import external libraries, so all data transformations and webhook payload handling must rely on these built-in modules.

Access webhook payloads in n8n Python Code nodes by referencing the body key within your input data. Apply safe dictionary access patterns to extract fields, then process the payload using standard library tools like json and hashlib for consistent return formats.

No, n8n Code nodes enforce a strict no external libraries rule for Python. You must perform batch and per-item data transformations using only the standard library, such as json, re, base64, and datetime, without importing third-party packages.

The correct return format for n8n Python Code nodes is a list of {"json": ...} objects. After processing input items with standard library functions, structure your output consistently as a list of these dictionaries to ensure downstream workflow nodes receive the transformed data.

Handle per-item data transformations in n8n Python Code nodes by iterating through _input.all() or accessing a single item with _input.first(). Apply standard library functions like re and datetime to each item, then return the transformed results as a list of {"json": ...} objects.

The primary limitation of Python in n8n Code nodes is the strict no external libraries rule. You are restricted to standard library modules like json, datetime, and math, and you must follow specific underscore data access patterns and consistent return formats to ensure safe execution.
