This avoids duplicating workflows and makes maintenance much easier.\n\n## How it works\n\nThe pattern is simple: **Normalize then Consolidate.**\n1. **Normalize:** Each trigger path has a `Set` node that reformats its unique output into a standard data structure with consistent key names.\n2. **Consolidate:** All paths then merge into a single `Set` node that uses the generic `$json` expression to accept the standardized data from whichever path ran. The rest of the workflow is now trigger-agnostic.\n\n## How to adapt this pattern\n\n1. **Replace the triggers** with your own.\n2. **Update the \"Normalize\" nodes:** After each of your triggers, use a `Set` node to map its specific output to a common schema.\n3. **Build your logic:** Connect all your \"Normalize\" nodes to the **\"Consolidate trigger data\"** node and build your main workflow from that point onward.\n\n\n\n*A template provided by Guillaume Duvernay*"
