How to Use the Loop Node in n8n — a Complete Guide with a Practical Example

By default n8n processes items in batches — but sometimes you need to walk through an array item by item: with API rate limits, delays, or per-item error handling. That is what the Loop Node (Split in Batches) is for.

What you will learn

• How to iterate over array items and process them one at a time.
• How to make an HTTP request for each item inside the loop.
• How to handle a single item's error without bringing down the whole loop.
• How to end the loop and collect the results of all iterations.

When to loop and when not to

In the episode I also show when a loop is unnecessary — many n8n nodes already execute per input item. The Loop Node makes sense when you need control over order, pace, or the reaction to a single item failing.
