Webpage Content Change Monitoring and Notification Workflow
This workflow is designed to automatically monitor content changes on specified web pages, regularly scraping the pages and using a hash algorithm to accurately identify changes. Subsequent actions are triggered only when actual content changes occur. The changed content will be saved to Google Drive and recorded in Google Sheets to ensure easy historical queries. Additionally, the system automatically sends email notifications to relevant personnel via Gmail, helping users stay informed about web updates in a timely manner, effectively saving time and labor costs.
