"content": "## Competitor Pricing Page Monitor\n\n### How it works\n\nThis workflow monitors a competitor pricing page once per day at 7AM. It compares the live page against a stored baseline, checks for API or comparison errors, and then determines whether the pricing page changed. It sends Slack alerts for detected price changes or comparison failures, while the no-change path ends without action.\n\n### Setup steps\n\n- Install the `n8n-nodes-snapshot-site` community node (Settings \u2192 Community nodes \u2192 Install \u2192 `n8n-nodes-snapshot-site`) \u2014 verified by n8n.\n- Configure the daily schedule trigger for the desired timezone and run time.\n- Set up the snapshot comparison node with the competitor pricing page URL and its baseline snapshot or comparison settings.\n- Connect valid Slack credentials and choose the channels/messages for price-change and comparison-failure alerts.\n- Verify the error and change-detection conditions match the response fields returned by the snapshot comparison service.\n\n### Customization\n\nAdjust the monitored URL, baseline snapshot, schedule frequency, Slack channels, and the sensitivity or matching rules used to decide whether a pricing page change is significant."
