Google Hotels Price Drop Alerts: Apify + Gmail (n8n)

Get alerted the moment your Google Hotels shortlist drops in price—automatically (Apify + Gmail in n8n)

This n8n workflow tracks hotel prices on Google Hotels every day and sends you an email via Gmail whenever a hotel you’re watching gets cheaper—no manual checking required.

What this workflow does

• Runs daily on a schedule to continuously monitor changes.
• Uses the Google Hotels Prices Scraper Apify Actor (https://apify.com/kestrel/google-hotels-prices) to read nightly rates and stay totals from Google Hotels, which compares multiple booking sources (e.g., Booking.com, Expedia, Agoda, Hotels.com, and the hotel’s own site).
• Detects price drops by storing yesterday’s price per hotel using n8n static data (no database setup).
• Applies a configurable drop threshold (default 10%) to determine what counts as a meaningful decrease.
• If any monitored hotels drop, it emails you the results through Gmail (you can swap the email node for another channel if desired).

Use cases

• SaaS operators and founders tracking travel costs for upcoming trips with predictable schedules (“N days out”).
• Automation engineers using n8n to build reliable daily monitoring without maintaining a price database.
• Frequent travelers who shortlist specific hotels and want price-drop alerts for those exact stays.

Technical details

• Scheduler trigger with relative dates (e.g., “30 days” → “32 days”) so the workflow doesn’t go stale.
• HTTP Request node calling Apify’s run-sync-get-dataset-items endpoint (one call can return up to 200 hotels).
• Code node compares current results vs previous run and emits only drop events.
• IF node gates the notification.
• Gmail node sends the email notification (upgrade path: Slack/Telegram/Google Sheets by replacing the last node).
• Uses sticky note, no op where applicable, and static data for persistence.

Setup: Create an Apify account and add your API token as a header auth credential named Apify Header Auth (header name is provided in the template’s setup instructions).
