The Booking Engine API powers a hotel’s direct booking funnel from end to end. Through a single session, you create a search context, return hotel, room, and rate availability, build a basket, quote it, and confirm a booking, with descriptions, promotions, loyalty, and sales terms available across the funnel. The Booking Engine API is stateful: you open a session, carry its identifier across calls, and update the search context, filters, and display options as the guest moves through the funnel.

​
How the funnel works

The funnel runs as a connected sequence of steps:

Create a session

Open a session with the search context: dates, guests, and an optional promo code. The API returns a sessionId that you carry on every later call and that holds the basket and context through the funnel.

Describe

For everything the guest sees, pull the descriptions of the rates, rooms, and hotels: text, pictures, amenities, and policies. These change rarely, so cache them to keep the interface fast.

Build a basket

When the guest settles on an offer, add the room and any extras to the basket. It holds their selection until you quote it.

Quote

Quote the basket for its current price and conditions, and fetch the sales terms to display to the guest. When the guest accepts the quote, the Accept a quote response returns a redirectionUrl to the payment page.

Payment

Once the guest is on that page, they enter their card and pay. Payment is hosted and handled by D-EDGE, so you never touch card details.

Confirmation

Once paid, the guest returns to the booking confirmation. It can be served by D-EDGE, or by the hotel’s own website when the Hotel Domain feature is enabled.
