Loop

Walk through an array one item at a time so downstream logic can repeat safely.

Overview#

Loop takes an array and exposes each entry along with its index. Downstream blocks can run the same logic for every item in a list.

Use it for batch enrichment, list processing, or any product that applies one template across many entries.

Max Iterations: Safety cap to prevent runaway loops.
Body Node IDs (optional): Explicit node IDs for the loop body on newer graphs , required for per-item execution when set.
Result Node ID (optional): Which body node output becomes each iteration result when body metadata is configured.

Confirm upstream output is actually an array before you connect Loop.
Set a sane max iteration limit for customer-supplied lists.
Keep the loop body simple , complex graphs inside loops are hard to debug.
Without body metadata on new graphs, the loop may pass the array through unchanged.

Ask the customer one clear question and turn their answer into data your workflow can use.

Collect several run-modal fields in one grouped form, each with a stable key for downstream steps.

Define what the customer receives when the workflow finishes.
