Post-booking reporting for Third-party inventory properties (TPI) properties

| New | inventory_type object | orders/details and orders/details/accommodations endpoints |

The inventory_type object has been added to the orders/details and orders/details/accommodations responses.

What this means:

  • Indicates whether the property is part of third-party inventory (TPI).
  • Specifies the applied rate type (e.g. sell or net).
  • Enables unified reporting for both Booking.com-sourced and TPI rates.

Example of orders/details response:

      "third_party_inventory": true,
      "inventory": {
        "third_party": true,
        "type": "sell"
      }

Find more details, see the Third-party inventory quick guide.

New original_total_price field under cancellation_details

| New | original_total_price field | orders/details/accommodations endpoint |

A new field called original_total_price has been added under the cancellation_details object in the orders/details/accommodations response.

What this means:

  • This represents the total amount that would have been charged if the booking had not been cancelled. Includes all charges, taxes, and mandatory fees.
  • It reflects the final payable amount at the time of booking, before any refunds or cancellations.
  • Helps partners better understand refund calculations in context of original booking value. Example:
"cancellation_details": {
  "at": "2025-06-15T10:42:00Z",
  "fee": {
    "accommodation_currency": 50.00,
    "booker_currency": 53.75

Bug fixes

Bug fixes
Title
Issue
Solution
✓Reservation modifications.In some cases, reservations could not be modified due to missing data at the time of booking.This has been resolved. New reservations can now be modified without issues.
✓Payment instructions for Japanese hotels.Payment instructions are not supported for many Japanese hotels due to a high rejection rate. However, some hotels incorrectly displayed a list of virtual cards in accommodations/details.This has been corrected. The list now appears empty to clearly indicate that payment instructions are not possible.
✓Missing details in important_information field (accommodations/details).The important_information field in accommodations/details was missing certain content.This has now been fixed. The field is aligned with the property's configuration in the extranet and accurately reflects all key guest-facing details.
