Overview
The Scripting node enables you to run custom code directly within your workflow, providing powerful programming capabilities for data processing, calculations, and logic implementation. With support for multiple programming languages and flexible variable management, this node serves as a versatile tool for complex workflow operations.
Language Configuration
Select Language
The language selection dropdown allows you to choose your preferred programming environment:
JavaScript - Full-featured JavaScript execution environment, ideal for web-based operations, JSON processing, and general-purpose scripting
Python - Complete Python runtime for data analysis, mathematical operations, and advanced processing tasks
The selected language determines the execution environment and available libraries for your script.

Error Detection: Built-in validation to identify syntax errors before execution
Variable Management System
Variables Section
The expandable Variables section provides dynamic variable management for your scripts:
Variable Definition Interface
Variable Name Field: Enter custom variable names (shown as "varOne" in the example)
Variable Value Field: Set variable values with placeholder "Enter number or words"
Add/Remove Functionality: Dynamic addition and removal of variables as needed
Delete Icon: Remove individual variables using the trash can icon
Information Icon: Access help documentation for variable usage
Variable Types Support
Numeric Values: Support for integers, floats, and mathematical expressions
String Values: Text data, including complex strings and formatted content
Boolean Values: True/false logical values for conditional operations
Array/Object Support: Complex data structures depending on the selected language
Execution and Output
Run Script Button
The prominent "Run Script" button initiates code execution:
Execution Trigger: Click to run your custom code with the defined variables
Real-time Processing: Immediate execution within the workflow environment
Error Handling: Comprehensive error reporting for debugging
Output Management
The node provides dual output streams for comprehensive result handling:
