Custom Function
Runs custom JavaScript and returns a value to the flow.
Coding
Use this when you need custom data logic but do not need to inject a script tag into the page.
When to use it
- Compute a value with JavaScript.
- Normalize a payload in one place before the next node.
Routing behavior
Continues through its connected downstream path when it completes successfully.
Properties
| Property | Type | Required | Details |
|---|---|---|---|
code code | code | Optional | JavaScript function body. Use return to pass data downstream. Available variables: $ (event data), $eventData (original data), $input (previous node output), $consent (consent state). DO NOT use {{ }} here. |
Common mistakes
- The function should return a value.
- Keep custom code short and intentional so flows stay maintainable.
