Automated Webpage Change Detector and Notifier
detail.loadingPreview
This workflow automatically monitors a specified webpage for content changes. It uses hashing to detect modifications and instantly notifies you via email, while also logging the changes to a Google Sheet for historical tracking.
About This Workflow
Never miss a critical update on your favorite websites or business-critical pages again. This powerful n8n workflow automates the process of monitoring online content. It begins by fetching the content of a designated URL, then calculates a unique hash of that content. By comparing this hash against previous versions, it efficiently detects any alterations. If a change is identified, the workflow immediately sends a detailed email notification, including the URL, timestamp, and a snapshot of the changed content. Additionally, all detected changes are meticulously logged into a Google Sheet, providing a comprehensive audit trail for future reference.
