How to Use

1. Select an Example - Choose from the dropdown or write your own
2. Edit Rules - Modify the rule JSON on the left panel
3. Edit Payload - Customize the input payload on the right panel
4. Process - Click “Process”, or press Ctrl/Cmd+Enter with the cursor in either editor
5. View Results - See the processed output with data, metadata, and audit trail

Tips

• Parse First - The payload is not part of the evaluation context. Start every rule with a parse_json action ({"source": "payload", "target": "input"}) and read the parsed value at data.input.… — that is what every built-in example does
• JSONLogic - Use JSONLogic expressions in your rules for dynamic data access and transformation
• Multiple Actions - Add multiple actions (tasks) to a rule for sequential processing
• Multiple Rules - Define multiple rules that execute in priority order
• Conditions - Add conditions to actions or rules to control when they execute (conditions can access data, metadata, and temp_data)
• Audit Trail - The output shows all changes made during processing
