Monitor website uptime and content changes with HTTP checks and Slack Workflow Solution

Workflow overview

Why this workflow matters

Potentially useful as a reusable automation building block.

Quick Overview This workflow runs every 30 minutes to check a list of website URLs, detect downtime or page content changes using HTTP requests and stored workflow state, and post alerts to a Slack channel only when something goes down, changes, or recovers. How it works Runs every 30 minutes on a schedule. Builds a list of target URLs (with labels) to monitor. Fetches each page with an HTTP GET request while capturing the full response and continuing even on 4xx/5xx errors. Compares each page’s current status code and content signature against the last saved value in AlekSystem workflow static data and updates the stored baseline. Posts a message to Slack only when a page is down, its content has changed, or it has recovered. Setup Add a Slack credential/connection and set the destination channel (for example, #alerts). Update the URL list (label and url fields) in the “Define URLs to Monitor” code step. Optionally adjust the schedule interval and HTTP timeout to match your monitoring needs.
