Set up automated availability alerts

Most users run this actor on a daily or weekly schedule to detect when sold-out hotels become available or when prices drop.

Step 1 — Schedule the run

In the Apify Console, open this actor → click Schedule → set frequency (daily at 08:00 is a good default).

Step 2 — Add a webhook

Go to Integrations → Webhooks → create one that fires on RUN_SUCCEEDED. Send results to Slack, email, or your own endpoint.

Step 3 — Compare runs over time

Each run produces a dataset. Export to Google Sheets or a database to track occupancy and price trends day over day.

Notes

• Sold out vs closed: available: false means either no rooms are listed at that price point, or the hotel enforces a minimum stay that excludes 1-night bookings.
• Currency: prices are in the currency Booking.com shows for the proxy location. Majority-currency filtering prevents mixed-currency averages.
• Hotel URL format: must be a direct hotel page — booking.com/hotel/<country>/<slug>.html. Dates in the URL are ignored; the actor always queries from today.
• Search URL: any Booking.com search page URL works. Filters (stars, property type, neighbourhood…) are preserved automatically.
• No browser required: HTTP-only. Fast and memory-efficient (512 MB).

Is it legal to scrape Booking.com?

This actor only accesses data that Booking.com makes publicly available to any visitor without a login. It does not bypass authentication, collect personal data, or perform actions a human user could not do manually. Ensure your use complies with Booking.com's terms of service, GDPR, and any applicable regulations.

Local development

cd booking-availability-monitor
npm install
# Edit storage/key_value_stores/default/INPUT.json to match input_schema prefill
apify run
# Or use a custom input:
apify run --input-file=./input.json

storage/key_value_stores/default/INPUT.json must include the urls field (required). The root input.json is for heavy local presets — it is ignored by apify run unless --input-file is used.
