## 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:

```bash
# 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
