Critical Node Patterns

String-Based API

workflow.add_node("PythonCodeNode", "node1", {
    "code": "result = input_data * 2"
})

Parameter Passing

workflow.add_connection("node1", "result", "node2", "input_data")

Common Nodes

• PythonCodeNode: Most flexible, use for custom logic
• SwitchNode: Conditional routing based on values
• CSVReaderNode: Reading CSV files
• APICallNode: HTTP API calls
• LoggerNode: Debug and production logging
