1. In Mews Operations, go to the main menu  > Marketplace.

2. Search for Booking.com, then click Explore.

4. In Marketplace > Booking.com integration, click Edit.

Ensure that Rates, Inventory, Room Categories, Payment & Cancellation Policies, and Age Categories match between Mews and the Booking.com Extranet.

Note: Do not enable the integration yet.

To configure your general Booking.com integration settings:

• Channel manager code: Copy and paste your Property ID from the Booking.com Extranet.
• Responsible department: Select the role for assigning who manages errors. If left blank, the system creates tasks that are unassigned.
• Notification email: Enter an email address to receive notifications such as mapping errors. Note: This does not include reservations.

Before enabling the integration, set up your operations. These actions happen automatically once you enable the integration's general settings.

• Download future reservations: Imports existing upcoming bookings from Booking.com. Note:
  • Keep disabled until testing is complete.
• Download mappings: Imports Extranet rates and room codes into Mews for easy mapping.
• Download reservations: Fetches new reservations from Booking.com after you go live.
• Push occupancy-based prices: Sends pricing updates based on occupancy.
• Upload availability, rates & restrictions: Syncs updates from Mews to Booking.com.

Pay close attention to:

• Apply cancellation fee: Uses the policy set in Mews.
• Create reservation from modification push: Ensures that the integration creates new reservations when bookings in Booking.com get modified.
• Enable more granular reporting: Do not enable.
• Use age category in inventory: Enable this only if age categories are set up correctly in Booking.com. If they are not set up correctly, untick this option to avoid the following errors,
  • reservations do not include the right age categories.
  • the system triggers an INVALID_GUEST_AGE_BAND_ID error in the channel manager queue. There is more information about this in the testing step.
• Use age category in reservations: If enabled, ensure you map age categories.

Other Settings

• Integration Key: Only needed if instructed. Note: Do not confuse this with the CHM code.
• Pricing: Choose Gross (VAT included) or Net (VAT excluded). Ensure same configuration across Mews, Extranet, and this setting. Note: You cannot update Pricing once you enable the integration.
• Last Inventory Update: Checks connection status.

Mews calculates and displays your space availability in Mews Operations and across distribution channels according to your existing space categories.

After you create a bookable service, you can then create the necessary space categories, for example, “Standard rooms”, “Deluxe rooms”, “Studios”, to organize your spaces by type, ensuring accurate availability, pricing, and occupancy data. Learn more in our help article How to create a space category in Mews Operations.

2. For each room type you want to map:

• Space Category Code: Copy the code from your Booking.com Extranet.
• Select Matching Category: Choose the corresponding space category in Mews from the dropdown.

2. Click Sync to send availability and restrictions for that room type to Booking.com.

3. Click Create, then repeat this process for each room category you want to sell on Booking.com.

Note: If you are using age-based pricing, ensure Mews and Extranet have matching age categories.

• Under Pull mapping, click Download.

2. Go to: Booking.com integration > Channel Manager Rates > + > Add rate.
