đź§ 10 practical ways to use $execution.customData like a pro
n8n gives us powerful no-code/low-code capabilities—but when it comes to state tracking, counters, flags, or conditional skips, the UI has its limits.
That’s where JavaScript and $execution.customData come in. With 10 slots per run, you can build:
- âś… Smart retry counters
- âś… Flag-based node skipping
- âś… Branch coordination logic
- âś… Execution time tracking
- âś… Debug toggles and more...
💡 I compiled 10 ready-to-use Function Item snippets that unlock these features — all using $execution.customData.get() and .set().

- Building resumable workflows
- Avoiding duplicated logic in IF/Switch nodes
- Creating pseudo-global variables in a single execution
