The V.2 API increases booking conversion by leveraging structured data. Additionally, it offers new features and new tools for efficient bulk inventory management.
Structured data
Use restructured, machine-readable data to increase your conversion. Data structuring updates enable comprehensive customization, deep filtering options (product quality, starting locations, itinerary types etc.), and simplified merchandising.
Modified-since endpoints
V.2 introduces modified-since endpoints for product and availability ingestion. These new endpoints enable partners to only update cached data which has changed, greatly reducing request load.
Real-time availability & pricing
V.2 provides simplified real-time availability and pricing, enabling partners to show consistently accurate data as their users prepare to book.
Booking hold functionality
Using V.2’s new booking hold function, partners may reserve availability while their users submit purchase details.
Streamlined reviews endpoint
Our v2 reviews endpoint comes with functionality not available on the v1 endpoint, such as:
- filtering reviews by provider
- supplier responses
- traveler photos (accessed previously through a separate endpoint)
- helpful votes
- choosing to include non-primary
- filter machine-translated reviews
