Booking.com to End Support for Older Roomrate API Versions on September 1, 2026, Impacting Product Creation
💸 September 1, 2026, Booking.com discontinues old connection versions (GET OTA_HotelProductNotif 1.0-1.2, POST 1.0), affecting roomrate creation. Any calls using outdated versions will fail with HTTP 400 errors. Providers with unversioned calls are auto-routed to version 1.3. This change coincides with a busy season for hotels, as commercial teams are creating new products. Therefore, hotels should verify any newly created products on Booking.com to ensure accuracy.
