Inventory & Pricing (ARI) XML Reference

Availability, Rates, and Inventory (ARI) is a Google Hotel Ads pricing feed that uses property data, room availability, and rate plans, to set pre-defined pricing strategies for properties.

ARI uses four different message types:

  • Transaction (Property Data). Defines rooms, packages (combinations of booking features such as refundability and amenities), and their mapping.
  • OTA_HotelRateAmountNotifRQ. Updates pricing for room rates.
  • OTA_HotelAvailNotifRQ. Updates availability, inventory, and restrictions for room rates.
  • TaxFeeInfo. Defines per-property taxes and fees. Alternatively, this message isn't required if AmountAfterTax is specified in the OTA_HotelRateAmountNotifRQ message.

Each message contains a subset of information that Google uses to compute the prices and availability displayed to users when they search for your properties with specific check-in and check-out dates and desired occupancy.

This XML reference guide provides detailed reference content and code examples for the different messages, elements, and attributes available for ARI feeds.
