Ready for 3.0. This template uses no nodes that n8n 3.0 removes. No removed nodes, versions or helpers found. Static check, last run 2026-10-19.

What this workflow does

This workflow has 4 nodes and runs when an HTTP GET request hits its webhook URL. It uses only n8n's built-in nodes.

How it runs

Trigger: When an HTTP GET request hits its webhook URL.

Extract & Parse Vectors (Edit Fields (Set)): sets 1 field: vectors
Validate & Compute Centroid (Code): runs custom JavaScript code
Return Centroid Response (Respond to Webhook): sends the response back to the webhook caller

Before you upgrade to n8n 3.0

Nothing in this workflow is removed in n8n 3.0, so it should import and run after the upgrade.
