N8n Workflow Templates

Permission Setup Review

python scripts/_tool_policy_note.py is an optional setup helper for the n8n Workflow Templates skill. It may apply broad filesystem permissions for compatibility. Show the target paths and permission mode, explain the risk, and prefer a narrower mode when shared write access is not needed.

API Reference

The scripts use n8n REST API v1:

GET  /api/v1/workflows          # List workflows
POST /api/v1/workflows          # Create workflow
GET  /api/v1/workflows/:id      # Get workflow
PUT  /api/v1/workflows/:id      # Update workflow
POST /api/v1/workflows/:id/activate    # Activate
POST /api/v1/workflows/:id/deactivate  # Deactivate

Full API docs: ${N8N_HOST}/api/v1/docs

Customizing Templates

Templates are standard n8n workflow JSON. Edit in n8n UI or modify the JSON directly:

# Copy and customize
cp templates/health-check.json my-custom-check.json
# Edit my-custom-check.json with your favorite editor
bash deploy.sh "$N8N_HOST" "$N8N_API_KEY" my-custom-check.json

Troubleshooting

"Unauthorized" error

• Verify API key is correct
• Check API key hasn't expired in n8n settings

"Connection refused"

• Verify n8n is running
• Check N8N_HOST includes correct port
• Ensure firewall allows connection

Workflow won't activate

• Check all credentials are configured in the workflow
• Verify webhook nodes don't conflict with existing webhooks
• Check n8n execution logs for errors

Template deployment fails

• Validate JSON: python3 -c "import json; json.load(open('template.json'))"
• Check n8n version compatibility (templates tested on v1.0+)

Requirements

• n8n instance v1.0 or later
• API access enabled in n8n settings
• curl and bash
• Network access to n8n instance
