Apify Pricing Page Change Monitor for n8n + Slack Alerts

Never miss a competitor price change—get automatic Slack alerts from n8n

This n8n workflow monitors competitor pricing pages every morning using Apify’s Website Change Monitor. When significant pricing changes are detected, it sends a detailed, Slack-ready alert to your chosen channel—so you can react fast without manually checking websites.

What this workflow does

• Runs daily at 9:00 on a schedule.
• You configure Pages to watch by listing each competitor pricing page with:
  • Page URL
  • An optional CSS selector (e.g., #pricing) to focus the monitoring area (leave empty to watch the whole page)
  • A display name
• The workflow runs Apify’s Website Change Monitor to snapshot the selected page sections and compare them to the previous baseline.
• It keeps only results where the page status is changed and the change is marked significant.
• For each significant change, it formats a message including:
  • Page name and URL
  • Detected numeric changes
  • The most relevant added/removed lines
• Finally, it posts the alerts to Slack in your configured destination channel.

Use cases

• Track SaaS competitor pricing changes to support marketing and sales positioning
• Monitor plan updates or discount pages to inform pricing strategy decisions
• Reduce manual monitoring with an Apify + Slack workflow for fast operational visibility

Technical details

• n8n nodes used: if, set, code, slack, sticky note, Apify node (apifyn8n-nodes-apify)
• Requires an Apify credential (API token/OAuth) and a Slack credential with a destination channel (e.g., #competitor-pricing).
