Turn important web page changes into Slack alerts
Ask Notis to render a page, compare it with the baseline you provide, and send the meaningful changes to Slack.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Post message to channel
Deprecated: posts a message to a slack channel, direct message, or private channel. use `send message` instead.
Why this helps
Checking key pages manually makes small but important updates easy to miss and pulls attention away from other work.
- See relevant page changes in a Slack message without repeatedly opening the site.
- Keep comparisons grounded in a baseline you provide.
- Make the alert easier to scan by asking Notis to summarize only material changes.
Setup
Build it in a few focused steps.
- 1Connect Cloudflare Browser Rendering and Slack once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a clear name and prompt.
- 3Tell Notis to render the requested page, compare it with a baseline included in the request, and post material changes to Slack.
- 4Choose a webhook trigger and select where run reports should go.
- 5Test with one real page and a baseline you provide.
Questions about this workflow
Where does the comparison baseline come from?
Include the baseline text or other usable reference in the webhook request. The workflow cannot assume that Cloudflare Browser Rendering keeps a historical version.
Can the automation monitor pages without a request?
This workflow uses a webhook, so an HTTP request starts each run. A scheduled run would need a notis_cron trigger and a defined page and baseline source.
