Automated Website Change Notifier with Telegram Alerts
detail.loadingPreview
Stay informed about critical updates on any website. This n8n workflow automatically monitors specified web pages for content changes and instantly sends you a notification via Telegram when a modification is detected, ensuring you never miss an important update.
About This Workflow
This powerful n8n workflow provides a robust solution for automated website change detection. Configured to run at regular intervals (e.g., every 5 minutes), it first fetches the current content of a target URL. After a brief wait, it performs a second fetch of the same page. By comparing the content from both requests, the workflow intelligently identifies any modifications. If a change is detected, a customizable alert is immediately dispatched to your designated Telegram chat, keeping you in the loop without manual checks. Ideal for tracking dynamic web content, competitor updates, or critical news.
Key Features
- Automated Website Monitoring: Set it and forget it – your chosen websites are checked periodically for changes.
- Instant Telegram Notifications: Receive real-time alerts directly to your mobile device when changes occur.
- Customizable Check Intervals: Adjust the frequency of monitoring and the delay between checks to suit your needs.
- No-Code Web Scraping: Easily fetch webpage content without writing any code.
- Flexible Alerting: Customize your Telegram message to provide specific details about the detected change.
How To Use
- Set up Cron Trigger: Configure the 'Cron' node to define how often the workflow should run (e.g., every 5 minutes).
- Define Target URL: In both 'HTTP Request' and 'HTTP Request1' nodes, specify the URL of the webpage you wish to monitor.
- Adjust Wait Time (Optional): Modify the 'Wait' node's 'Amount' and 'Unit' parameters to control the delay between the initial and subsequent web content fetch.
- Configure Change Detection (Crucial): Update the 'IF' node's conditions to accurately compare the data from 'HTTP Request' and 'HTTP Request1'. For example, set
Value 1to{{$node["HTTP Request"].json["data"]}},OperationtoNot Equal, andValue 2to{{$node["HTTP Request1"].json["data"]}}. - Set up Telegram Alerts: Provide your 'chatId' in the 'Telegram1' node and customize the 'Text' message that will be sent upon detecting a change. Ensure your Telegram API credentials are set up in n8n.
