Tripadvisor Hotel Availability Check API

The Tripadvisor Hotel Availability Check (HAC) API allows hotel booking partners to display their availability and pricing on Tripadvisor. When a user views a hotel page, Tripadvisor sends HTTP POST requests to the partner's API to retrieve real-time price and availability data. The API supports batch requests for multiple hotels and requires responses within 5 seconds on average. The current version (v8) provides richer availability data to help partners increase conversions.
