Executes schedule routines, and triggers alerts via telegram

1364-cron-routines-with-telegram

This n8n workflow provides a basic template for triggering routines on a schedule or via a webhook, with the capability to interact with a MySQL database and send messages to Telegram. It's a foundational setup for automating tasks that require scheduled execution, external triggers, database interaction, and user notifications.

What it does

This workflow demonstrates a flexible triggering mechanism and the integration of database operations and messaging:

Scheduled Trigger: The workflow can be initiated at predefined intervals using the Cron node. This allows for routine tasks to be automated without manual intervention.
Manual/External Trigger: Alternatively, the workflow can be started manually within n8n or triggered by an external system via a Webhook. This provides flexibility for on-demand execution or integration with other services.
Database Interaction (MySQL): It includes a MySQL node, indicating the capability to perform database operations such as querying, inserting, updating, or deleting data. This is useful for routines that involve data management.
Telegram Notifications: The workflow is set up to send messages to Telegram, enabling it to deliver notifications, alerts, or reports to a specified chat or user.

Prerequisites/Requirements

n8n Instance: A running n8n instance to import and execute the workflow.
Telegram Account & Bot: A Telegram account and a Telegram Bot token to send messages. You'll need to create a bot via BotFather on Telegram and obtain its API token.
MySQL Database: Access to a MySQL database with appropriate credentials if you intend to use the MySQL node for actual database operations.

Setup/Usage

Import the Workflow:
- Save the provided JSON content as a .json file.
- In your n8n instance, go to "Workflows" and click "New".
- Click the "Import from JSON" button and paste the workflow JSON or upload the saved file.
Configure Credentials:
- Telegram:
  - Locate the "Telegram" node.
  - Click on "Credential" and select "Create New".
  - Choose "Telegram API" as the credential type.
  - Enter your Telegram Bot Token (obtained from BotFather).
  - Save the credential.
- MySQL:
  - Locate the "MySQL" node.
  - Click on "Credential" and select "Create New".
  - Choose "MySQL" as the credential type.
  - Fill in your MySQL database credentials (host, port, database, user, password).
  - Save the credential.
Configure Triggers:
- Cron: If you want to use the scheduled trigger, configure the "Cron" node with your desired schedule (e.g., "Every day at 9 AM").
- Webhook: If you plan to trigger the workflow via a webhook, activate the "Webhook" node and copy its URL. You can then send HTTP requests to this URL to start the workflow.
- Start: The "Start" node is for manual execution within n8n.
Customize Workflow Logic:
- Modify the "MySQL" node to perform your specific database queries or commands.
- Adjust the "Telegram" node to send the desired messages, potentially including dynamic data from previous nodes.
Activate the Workflow: Once configured, activate the workflow by toggling the "Active" switch in the top right corner of the workflow editor.

Demo Personalized Email This n8n workflow is built for AI and automation agencies to promote their workflows through an interactive demo that prospects can try themselves. The featured system is a deep personalized email demo. --- 🔄 How It Works Prospect Interaction A prospect starts the demo via Telegram. The Telegram bot (created with BotFather) connects directly to your n8n instance. Demo Guidance The RAG agent and instructor guide the user step-by-step through the demo. Instructions and responses are dynamically generated based on user input. Workflow Execution When the user triggers an action (e.g., testing the email demo), n8n runs the workflow. The workflow collects website data using Crawl4AI or standard HTTP requests. Email Demo The system personalizes and sends a demo email through SparkPost, showing the automation’s capability. Logging and Control Each user interaction is logged in your database using their name and id. The workflow checks limits to prevent misuse or spam. Error Handling If a low-CPU scraping method fails, the workflow automatically escalates to a higher-CPU method. ⚙️ Requirements Before setting up, make sure you have the following: n8n — Automation platform to run the workflow Docker — Required to run Crawl4AI Crawl4AI — For intelligent website crawling Telegram Account — To create your Telegram bot via BotFather SparkPost Account — To send personalized demo emails A database (e.g., PostgreSQL, MySQL, or SQLite) — To store log data such as user name and ID 🚀 Features Telegram interface using the BotFather API Instructor and RAG agent to guide prospects through the demo Flow generation limits per user ID to prevent abuse Low-cost yet powerful web scraping, escalating from low- to high-CPU flows if earlier ones fail --- 💡 Development Ideas Replace the RAG logic with your own query-answering and guidance method Remove the flow limit if you’re confident the demo can’t be misused Swap the personalized email demo with any other workflow you want to showcase --- 🧠 Technical Notes Telegram bot created with BotFather Website crawl process: Extract sub-links via /sitemap.xml, sitemap_index.xml, or standard HTTP requests Fall back to Crawl4AI if normal requests fail Fetch sub-link content via HTTPS or Crawl4AI as backup SparkPost used for sending demo emails --- ⚙️ Setup Instructions Create a Telegram Bot Use BotFather on Telegram to create your bot and get the API token.

Automate Reddit brand monitoring & responses with GPT-4o-mini, Sheets & Slack

How it Works This workflow automates intelligent Reddit marketing by monitoring brand mentions, analyzing sentiment with AI, and engaging authentically with communities. Every 24 hours, the system searches Reddit for posts containing your configured brand keywords across all subreddits, finding up to 50 of the newest mentions to analyze. Each discovered post is sent to OpenAI's GPT-4o-mini model for comprehensive analysis. The AI evaluates sentiment (positive/neutral/negative), assigns an engagement score (0-100), determines relevance to your brand, and generates contextual, helpful responses that add genuine value to the conversation. It also classifies the response type (educational/supportive/promotional) and provides reasoning for whether engagement is appropriate. The workflow intelligently filters posts using a multi-criteria system: only posts that are relevant to your brand, score above 60 in engagement quality, and warrant a response type other than "pass" proceed to engagement. This prevents spam and ensures every interaction is meaningful. Selected posts are processed one at a time through a loop to respect Reddit's rate limits. For each worthy post, the AI-generated comment is posted, and complete interaction data is logged to Google Sheets including timestamp, post details, sentiment, engagement scores, and success status. This creates a permanent audit trail and analytics database. At the end of each run, the workflow aggregates all data into a comprehensive daily summary report with total posts analyzed, comments posted, engagement rate, sentiment breakdown, and the top 5 engagement opportunities ranked by score. This report is automatically sent to Slack with formatted metrics, giving your team instant visibility into your Reddit marketing performance. --- Who is this for? Brand managers and marketing teams needing automated social listening and engagement on Reddit Community managers responsible for authentic brand presence across multiple subreddits Startup founders and growth marketers who want to scale Reddit marketing without hiring a team PR and reputation teams monitoring brand sentiment and responding to discussions in real-time Product marketers seeking organic engagement opportunities in product-related communities Any business that wants to build authentic Reddit presence while avoiding spammy marketing tactics --- Setup Steps Setup time: Approx. 30-40 minutes (credential configuration, keyword setup, Google Sheets creation, Slack integration) Requirements: Reddit account with OAuth2 application credentials (create at reddit.com/prefs/apps) OpenAI API key with GPT-4o-mini access Google account with a new Google Sheet for tracking interactions Slack workspace with posting permissions to a marketing/monitoring channel Brand keywords and subreddit strategy prepared Create Reddit OAuth Application: Visit reddit.com/prefs/apps, create a "script" type app, and obtain your client ID and secret Configure Reddit Credentials in n8n: Add Reddit OAuth2 credentials with your app credentials and authorize access Set up OpenAI API: Obtain API key from platform.openai.com and configure in n8n OpenAI credentials Create Google Sheet: Set up a new sheet with columns: timestamp, postId, postTitle, subreddit, postUrl, sentiment, engagementScore, responseType, commentPosted, reasoning Configure these nodes: Brand Keywords Config: Edit the JavaScript code to include your brand name, product names, and relevant industry keywords Search Brand Mentions: Adjust the limit (default 50) and sort preference based on your needs AI Post Analysis: Customize the prompt to match your brand voice and engagement guidelines Filter Engagement-Worthy: Adjust the engagementScore threshold (default 60) based on your quality standards Loop Through Posts: Configure max iterations and batch size for rate limit compliance Log to Google Sheets: Replace YOURSHEETID with your actual Google Sheets document ID Send Slack Report: Replace YOURCHANNELID with your Slack channel ID Test the workflow: Run manually first to verify all connections work and adjust AI prompts Activate for daily runs: Once tested, activate the Schedule Trigger to run automatically every 24 hours --- Node Descriptions (10 words each) Daily Marketing Check - Schedule trigger runs workflow every 24 hours automatically daily Brand Keywords Config - JavaScript code node defining brand keywords to monitor Reddit Search Brand Mentions - Reddit node searches all subreddits for brand keyword mentions AI Post Analysis - OpenAI analyzes sentiment, relevance, generates contextual helpful comment responses Filter Engagement-Worthy - Conditional node filters only high-quality relevant posts worth engaging Loop Through Posts - Split in batches processes each post individually respecting limits Post Helpful Comment - Reddit node posts AI-generated comment to worthy Reddit discussions Log to Google Sheets - Appends all interaction data to spreadsheet for permanent tracking Generate Daily Summary - JavaScript aggregates metrics, sentiment breakdown, generates comprehensive daily report Send Slack Report - Posts formatted daily summary with metrics to team Slack channel
