Adding Booking.com Through rezStream Channels, Powered by Channex

This article explains how to connect your Booking.com account through rezStream Channels, powered by Channex. It covers preparing the Booking.com extranet, creating the connection, mapping units, activating the channel, and understanding the supported functionality.

Before You Begin: Connecting Booking.com to rezStream Channels, Powered by Channex 

You will need:

  • Access to the property's Booking.com extranet ccount
  • Access to the property's rezStream Cloud account
  • The property's Booking.com Hotel ID
  • The correct currency for the property
  • Knowledge of the property's Booking.com's unit and rate plans

Find the Booking.com Expedia Hotel ID

  1. Log into the property's Booking.com Extranet.

  2. Locate the property's Hotel ID, which is displayed near the property name on the main page. Record this ID, as it will be required during the setup process in rezStream Cloud.

Check the Existing Booking.com Connectivity Settings

Before connecting Channex, make sure another channel manager is not currently connected to Booking.com. 

  1. Click Account in the upper-right corner.
  2. Select Connectivity Provider.

If Another Channel Manager Is Connected

  1. Click Switch Providers.

 If Another Channel Manager Is Not Connected

  1. Click Search.
  2. Search for Channex.
  3. Select Channex.io from the results.

Once Channex has been selected as the connectivity provider, click Accept or Next at the bottom of the page.

When the connection has been approved, Booking.com will display a green checkmark confirming the connection is active. At this point you are ready to configure the channel within rezStream Cloud.

Creating the Booking.com Channel in rezStream Cloud

  1. Navigate to: Integrations → rezStream Channels
  2. Select the Channels tab.
  3. Click Create.
  4. Select Booking.com from the Channel list.

General Settings

  1. Title
    Enter a descriptive name for the connection, such as:
    Property Name - Booking.com
  2. Booking.com Hotel ID
    Under Connection Settings, enter the property’s Booking.com Hotel ID obtained from the Booking.com Extranet.
  3. Advanced Settings — Optional
    These settings determine which types of Booking.com reservation changes will trigger a modification to be downloaded into rezStream Cloud. Available options include:
    • VCC: Downloads changes related to the reservation’s Virtual Credit Card.
    • Payout: Downloads changes to the reservation’s payout amount.
    • Payout Method: Downloads changes to the payment method, such as a change from VCC to Bank Transfer.
    • VCC Balance: Downloads changes to the remaining Virtual Credit Card balance.
    • VCC Fees Payout: Downloads changes related to payment fees.
    Important: Use these settings only when needed. Enabling certain options—particularly VCC Balance—can result in a large number of reservation modifications being downloaded, especially when currency exchange rates fluctuate.

Test the Connection

After entering the Hotel ID:

  1. Click Test Connection.

If the connection is successful, a Successful Connection message will appear.

If the connection is unsuccessful, verify the Hotel ID and Booking.com Connectivity Provider settings. If the problem persists, contact Support.

Map the Units

After receiving a successful connection:

  1. Open the Mapping tab.
  2. Click Not Mapped beside each Booking.com room.
  3. Select the matching rezStream Cloud Unit or Unit Type.

The Number of Guests represents the property's Base Capacity.

Unless the property uses a single occupancy pricing model, select the base occupancy that matches the configured Unit Type.

Important: Every Booking.com room and occupancy level should be mapped. Leaving mappings blank may result in reservation download errors or unmapped bookings.

Channel Settings (Optional)

The Channel Settings tab allows pricing adjustments that apply only to Booking.com.

You may configure:

  • A rate increase
  • A rate decrease

Then enter the desired adjustment amount.

These adjustments affect only Booking.com and do not modify the property's standard rates.

Save and Activate the Channel

Once the configuration is complete:

  1. Click Save.

Depending on the account, you may see:

  • Save & Activate, or
  • Save

If only Save is available:

  1. Save the channel.
  2. Return to the Channels tab.
  3. Click Actions beside the Booking.com channel.
  4. Select Activate.

Once activated, the channel status should display Active.

Running a Full Sync

A Full Sync manually sends rates, availability, and restrictions to Booking.com.

Although a manual Full Sync is generally not required, it may be helpful after major configuration changes.

To perform a Full Sync:

  1. Navigate to the Channels tab.
  2. Click Actions beside the Booking.com channel.
  3. Select Full Sync.

Configure the Reservation Source

You can assign a Source to the Booking.com channel so that all reservations downloaded from Booking.com are automatically tagged with the appropriate Source. This makes it easier to track, identify, and report on Booking.com reservations within rezStream Cloud.

  1. Go to Channel Tenant Settings > Channel Mappings 
  2. Assign the reservation Source for Booking.com.

If a Booking.com source has not yet been created:

  1. Navigate to: Configuration → Source of Contact and Reason for Stay
  2. Open the Sources tab.
  3. Click Add New Source.
  4. Create a source named Booking.com.
  5. Return to Channel Mappings and assign the newly created source.

Downloaded reservations will automatically use this source.

Information Sent to Booking.com

The Booking.com integration currently supports:

  • Rates
  • Availability
  • Minimum Night Requirements

The following information is not sent:

  • Packages
  • Fees
  • Taxes
Note: If the property has a Relax Rule configured within Booking.com, guests may still be able to book fewer nights than the property's configured minimum stay. If this occurs, the property should contact their Booking.com Account Manager for assistance.

Derived Rate Plans

Booking.com Derived Rate Plans generally do not require mapping.

Newly created derived rates typically behave like promotions and automatically function without additional mapping.

However, some older Booking.com accounts may still display derived rates as mappable within Channex.

If this occurs, there are two options:

Option 1 (Recommended)

Map every available rate, including the derived rates.

If derived rates remain unmapped, reservation download errors may occur.

Option 2

Delete the older derived rates within the Booking.com Extranet and recreate them.

Newly created derived rates should no longer appear as mappable and will function correctly without additional mapping.

Supported Functionality

The Booking.com integration currently supports:

  • ARI updates (Availability, Rates, and Restrictions)
  • Downloading reservations
    • New reservations
    • Modified reservations
    • Cancelled reservations
  • Sending rates to Booking.com
  • Sending availability
  • Sending minimum night restrictions

Not Currently Supported

The Booking.com integration does not currently send:

  • Taxes
  • Fees
  • Packages 
  • Images 
  • Descriptions 
  • Messages 

These items must be managed directly within the Booking.com Extranet.

Best Practices

  • Verify that Channex has been selected as the property's Connectivity Provider before testing the connection.
  • Record the correct Booking.com Hotel ID before creating the channel.
  • Map every room and occupancy level to prevent reservation download issues.
  • Configure a Booking.com reservation source before activating the channel.
  • Run a Full Sync after setup if immediate rate and availability updates are needed.
  • If older derived rate plans appear in Channex, either map them or recreate them within Booking.com.
