Overview
The Loop step iterates over an array and executes nested child steps for each item. On the canvas, the loop appears as a container node — drag child steps inside it to define the logic that runs per iteration.
Configuration
| Field | Description |
|---|
| Iterator Path | Path to the array to iterate over (template variable) |
| Mode | Sequential or Parallel (with configurable batch size) |
| Delay | Milliseconds to wait between iterations |
| Max Iterations | Maximum number of iterations (capped at 10,000) |
| Error Handling | Continue (skip failed items) or Stop (halt on first error) |
Execution Modes
| Mode | Description |
|---|
| Sequential | Items are processed one at a time in order |
| Parallel | Items are processed concurrently. Set a batch size to control how many run at once. |
Accessing Loop Data
Inside child steps, use these template variables:
| Variable | Description |
|---|
{{iteration.item}} | The current item being processed |
{{iteration.item.field}} | A specific field on the current item |
{{iteration.parent.*}} | Parent loop context when loops are nested |
Nesting Loops
Loops can be nested by placing one loop inside another on the canvas. Use {{iteration.parent.item}} to access the outer loop’s current item from within the inner loop.
When dragging a step over overlapping loops, the canvas places it in the innermost loop automatically. You can also move a step from one loop to another at any time — drag it to the target loop and release when the loop highlights. To remove it from a loop, drag it outside the loop’s boundary.
Output
| Field | Type | Description |
|---|
data | array | Results from all iterations |
success | boolean | Whether the loop completed |
success_count | number | Number of successful iterations |
error_count | number | Number of failed iterations |
