Node Inputs

​
Required Fields

Input Data:
The array or collection to iterate over.
Example: ["item1", "item2", "item3"] or [{"name": "John"}, {"name": "Jane"}]

​
Optional Fields

Loop Variable Name:
The name of the variable to use for the current item.
Example: "item"
Default: "item" Index Variable Name:
The name of the variable to use for the current index.
Example: "index"
Default: "index" Max Iterations:
Maximum number of iterations to execute (safety limit).
Example: 1000
Default: No limit Batch Size:
Number of items to process in each batch.
Example: 10
Default: 1 (process one at a time) Continue on Error:
Whether to continue loop execution if an iteration fails.
Example: true
Default: false

​
Node Output

Loop Results:
An array containing the results from each iteration. Example Output: 
{
  "total_iterations": 3,
  "successful_iterations": 3,
  "failed_iterations": 0,
  "results": [
    {
      "iteration": 0,
      "item": "item1",
      "result": "processed item1",
      "status": "success"
    },
    {
      "iteration": 1,
      "item": "item2",
      "result": "processed item2",
      "status": "success"
    },
    {
      "iteration": 2,
      "item": "item3",
      "result": "processed item3",
      "status": "success"
    }
  ],
  "execution_time": 1.25
}

Node Functionality

The Loop Node:
  • Iterates over arrays and collections.
  • Executes workflow steps for each item.
  • Provides access to current item and index in nested nodes.
  • Supports batch processing for efficiency.
  • Handles errors gracefully with continue-on-error option.
  • Collects and returns results from all iterations.
  • Essential for processing lists, CSV rows, API paginated results, etc.
