Quick Start

Installation

npm install n8n-nodes-vars-pro

Using Workflow Templates

Note: n8n community nodes cannot be directly integrated into the right-side Templates panel (which is based on n8n cloud services). Please use the following methods to import templates.

Method 1: Copy JSON Directly (Recommended)

Copy the following JSON code and paste it into the n8n editor using Ctrl+V (Windows) or Cmd+V (Mac):
