Hotel API integration connects your booking website to hotel suppliers such as bedbanks and wholesalers, so customers can search and book hotels in real time. Most hotel APIs follow a similar flow, even though details differ by supplier. This article explains that flow step by step, so you understand what happens when a customer books a hotel on your site.
1. Static content
Before any search, the booking engine downloads static hotel content from the supplier: hotel names, addresses, star ratings, coordinates, descriptions, photos and amenities. This content is stored and refreshed regularly, and mapped to your master hotel list if you use several suppliers.
2. Availability search
The customer enters destination, dates, rooms and guests. The engine sends an availability request to each supplier and receives hotels with available rooms and prices. Results are merged, duplicates removed and markups applied.
3. Room and rate details
When the customer opens a hotel, the engine shows room types, board basis, prices and cancellation policies. Some suppliers return all room options in the search; others require a separate request for full details.
4. Price and policy check
Before payment, the engine checks the selected rate again. Prices and cancellation policies can change between search and booking, so this step confirms exactly what the customer will pay and what they can cancel.
5. Booking
After payment, or before it for pay-later bookings, the engine sends a booking request with guest names and special requests. The supplier returns a booking reference and status: confirmed, on request or failed.
6. Voucher and confirmation
The customer receives a voucher with hotel details, room, board, guest names, check-in information and the supplier reference. Some suppliers also provide a hotel confirmation number shortly before arrival.
7. Cancellation
When a customer cancels, the engine sends a cancellation request. The supplier confirms and returns any penalty according to the policy. The engine then calculates the customer refund and records it.
8. Reconciliation and payment
Suppliers invoice or debit you for bookings according to your agreement. Regular reconciliation matches supplier statements with your bookings and cancellations.
Things that commonly go wrong
- Price changes at booking: handled by the price check step.
- Missing taxes payable at the hotel: show them clearly.
- Duplicate hotels: solved with hotel mapping.
- Slow suppliers: use timeouts and progressive results.
In practice: one booking traced through the flow
A traveller searches Goa for three nights. Two suppliers return results; the engine merges them and shows the lowest rate for each hotel. The traveller chooses a resort with breakfast and free cancellation until a week before arrival. The engine rechecks the rate, takes payment, books with the supplier and sends a voucher. Two weeks later the traveller cancels; the engine confirms there is no penalty and refunds the full amount.
