# n8n Workflow Automation Skill This skill enables creating and managing n8n workflows for automation tasks. ## Prerequisites n8n instance running with API access: ```bash N8N_HOST=localhost N8N_PORT=5678 N8N_API_KEY=your-api-key ``` ## Core Concepts ### Workflow Structure Every n8n workflow is JSON with this structure: ```json { "name": "Workflow Name", "nodes": [], "connections": {}, "settings": { "executionOrder": "v1" } } ``` ### Node Structure Each node has: ```json { "id": "unique-id", "name": "Display Name", "type": "n8n-nodes-base.nodetype", "typeVersion": 1, "position": [x, y], "parameters": {}, "credentials": {} } ``` ### Connection Structure Connections define data flow between nodes: ```json { "Source Node": { "main": [ [{"node": "Target Node", "type": "main", "index": 0}] ] } } ``` ## Common Workflow Patterns ### 1. Webhook-Triggered Workflow Creates an HTTP endpoint that triggers workflow execution: ```json { "name": "Webhook Handler", "nodes": [ { "id": "webhook", "name": "Webhook", "type": "n8n-nodes-base.webhook", "typeVersion": 2, "position": [250, 300], "webhookId": "my-webhook", "parameters": { "path": "my-endpoint", "httpMethod": "POST", "responseMode": "responseNode" } }, { "id": "respond", "name": "Respond", "type": "n8n-nodes-base.respondToWebhook", "typeVersion": 1.1, "pos...
