# n8n Workflow Templates Deploy production-ready n8n workflows in seconds. Five battle-tested templates plus management scripts for the complete n8n workflow lifecycle. ## Quick Start ```bash # Set your n8n credentials export N8N_HOST="http://localhost:5678" export N8N_API_KEY="n8n_api_xxxxx" # List existing workflows bash list-workflows.sh # Deploy a template bash deploy.sh "$N8N_HOST" "$N8N_API_KEY" templates/webhook-to-telegram.json ``` ## Templates | Template | Description | Use Case | |----------|-------------|----------| | `webhook-to-telegram.json` | Webhook receiver → Telegram alerts | Instant notifications from any service | | `rss-monitor.json` | RSS feed monitoring with filtering | Track blogs, news, releases | | `health-check.json` | HTTP health checks with alerts | Monitor services, APIs, websites | | `social-metrics.json` | Scheduled social media collection | Track followers, engagement | | `data-backup.json` | Automated backup with notifications | Database/file backups | ## Detailed Usage ### Environment Variables | Variable | Required | Default | Description | |----------|----------|---------|-------------| | `N8N_HOST` | Yes | - | n8n instance URL | | `N8N_API_KEY` | Yes | - | API key from n8n settings | ### Deployment ```bash bash deploy.sh <n8n-url> <api-key> <template-file> [workflow-name] ``` **Arguments:** - `n8n-url` - Full URL to n8n instance (e.g., `http://10.0.0.120:5678`) - `api-key` - n8n API key - `template-file` - Path to workflow JSON file - `workflow-name` (optional) - Override the workflow name **Example:** ```bash bash deploy.sh "http://10.0.0.120:5678" "n8n_api_abc123" templates/health-check.json "My Health Monitor" ``` ### Listing Workflows ```bash bash list-workflows.sh <n8n-url> <api-key> ``` Lists all active workflows with their IDs, names, and activation status. ## Template Details ### webhook-to-telegram Receives HTTP POST requests, processes JSON payload, sends formatted messages to Telegram. **Webhook URL:** `${N8N_HOST}/webhook/workflow-id` **Expected payload:** ```json { "message": "Alert from my service", "level": "warning", "timestamp": "2026-02-10T22:00:00Z" } ``` **Required setup:** Configure Telegram bot token and chat ID in the workflow. ### rss-monitor Monitors RSS feeds on schedule, filters by keywords, alerts on new items. **Features:** - Runs every 15 minutes - Keyword filtering (include/exclude) - Duplicate detection - Multi-channel alerts (Telegram, Discord, email) **Required setup:** Set RSS feed URL and alert destination. ### health-check Performs HTTP health checks, alerts on failure, tracks response times. **Features:** - Configurable check interval - Response time thresholds - Consecutive failure alerts - Status history tracking **Required setup:** Set target URLs and alert channels. ### social-metrics Collects social media metrics on schedule, stores for trending. **Features:** - Daily metric collection - Multi-platform support (X/Twitter, LinkedIn, etc.) - Data storage in n8n or external DB - Trend analysis ready **Required setup:** Configure API credentials for each platform. ### data-backup Automated backup workflow with pre/post checks and notifications. **Features:** - Schedule-based execution - Pre-backup validation - Backup verification - Success/failure notifications - Retention policy enforcement **Required setup:** Configure backup source, destination, and credentials. ## API Reference The scripts use n8n REST API v1: ``` GET /api/v1/workflows # List workflows POST /api/v1/workflows # Create workflow GET /api/v1/workflows/:id # Get workflow PUT /api/v1/workflows/:id # Update workflow POST /api/v1/workflows/:id/activate # Activate POST /api/v1/workflows/:id/deactivate # Deactivate ``` Full API docs: `${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 ## See Also - n8n Documentation: https://docs.n8n.io/ - n8n API Reference: https://docs.n8n.io/api/ - Workflow examples: https://n8n.io/workflows/
