N8N
n8n Overview
Learn what n8n is and how to use it on OpenCloud for AI-powered workflow automation.
n8n — AI Workflow Automation
n8n (pronounced "n-eight-n") is a powerful workflow automation tool that lets you connect different apps and services together without writing code. Build AI-powered automations that connect to any service.
What can you do with n8n?
- Build AI-powered automations — Connect LLMs to your workflows for intelligent processing
- Post a Slack message when a new order comes in on your website
- Send a daily summary email with data from a spreadsheet
- Sync contacts between your CRM and email marketing tool
- Monitor a website and get notified when it goes down
- Process form submissions and add them to a database
How it works
n8n uses a visual workflow editor where you drag and drop "nodes" (building blocks) and connect them together:
- Trigger nodes start the workflow (e.g., "when a new email arrives", "every day at 9 AM")
- Action nodes do something (e.g., "send a Slack message", "create a database record")
- Logic nodes make decisions (e.g., "if the amount is over $100, do X; otherwise, do Y")
