Overview

This node implements a looping mechanism within n8n workflows, allowing repeated execution of subsequent nodes or actions. It is useful for scenarios where you need to iterate over a set of items or repeatedly perform a task until a condition is met. For example, it can be used to process batches of data, retry operations multiple times, or create custom loops in automation workflows.

Use Case Examples

1. Processing a list of items in batches by looping through each batch.
2. Retrying an API call multiple times until a successful response is received.
3. Creating a custom loop to perform a series of actions repeatedly based on dynamic conditions.

Output

JSON

• loopCount - The current iteration count of the loop
• loopData - Data associated with the current loop iteration

Dependencies

• An API key credential for the loop API

Troubleshooting

• Ensure the loop API credential is correctly configured to avoid authentication errors.
• If the loop does not behave as expected, verify the workflow logic and conditions controlling the loop iterations.
• Timeouts or infinite loops can occur if exit conditions are not properly set; always define clear stopping criteria.
