Update rates

Use the availability endpoint to:

Set adult prices by specifying room type, rate plan and date.

Booking.com supports different pricing models. Ensure you're using the correct pricing approach for your property For more information on pricing models, see Pricing Models.

Usage recommendations

Specify availability in advance: Provide availability for at least 12 months ahead.
Use Delta Updates Only: Send only changes using the roomRateAvailability API, not full refreshes.
Single Hotel Per Request: All updates must belong to one hotel only.
Monthly Batching: Break down updates by month: one month per request.
Room-Rate Grouping: Multiple room-rates can be grouped in the same request for the same hotel and month.

Additional information

Day of week behavior

When specifying days of the week (Mon, Tue, Wed, Thu, Fri, Sat, Sun):

If you set some days to true and omit others, the omitted days default to false
If you explicitly set some days to false without setting any to true, all days will be treated as true
If all day attributes are omitted, all days default to true

Price limits and validation

v1.0 behavior: €50,000 maximum price

The maximum price you can set for a room is €50,000 (or equivalent) per night.

Setting availability for child rates

While setting up availability using rate IDs that are configured as child rates, make sure the request doesn't set values for fields that are configured to inherit from the parent rate plan.

For example, if you try to set price when FollowsPrice is set, the API returns an error.

To resolve the error, specify a rate plan ID that is either configured as a parent rate, or a child rate that does not have the following restrictions: FollowsPrice
