Travel API integration for flights, hotels and ground services
Connect GDS, NDC, low-cost carrier and bed-bank APIs to your business through one normalised layer — as a single REST API for your own booking engine, inside a ready-made booking platform, or both. 110+ supplier connections are already in production.

What travel API integration involves
Travel API integration connects your booking system to suppliers' interfaces so it can search, price, book, ticket and service their inventory automatically. Each supplier uses its own format, fare logic and booking lifecycle; the work is turning them into one consistent data model your agents, customers and finance team can rely on.
How we deliver the connections
Supplier APIs we connect
Certified Partner means the supplier has certified Innovate Solution; Partner Integration means the connection is live without a certification record; Technology Integration means availability should be confirmed for your market.
GDS networks
NDC and airline direct
Low-cost carriers
Hotels and bed-banks
What a production-grade integration has to handle
A demo that returns fares is the easy 10%. These are the parts that decide whether an integration survives real booking volume — and what we have already built.
Normalisation
GDS, NDC and low-cost fares arrive in different structures. They are merged into one normalised search, so a full-service, NDC and low-cost option can be compared in one result with your markups applied.
Booking lifecycle
Ticketing is only the start. PNR import, transfer, void, refund and reissue run as single actions; see the void and refund walkthrough.
Multi-GDS ticketing
Tickets can be issued across several airlines and GDS networks dynamically — documented in our multi-GDS ticketing case study.
Agent workflows
An integrated GDS terminal with native cryptic commands sits beside the booking screens, so experienced ticketing staff keep working the way they know (case study).
Fare rules people can read
Long, text-based GDS fare rules are restructured with AI into readable conditions for agents and customers (case study).
Margin and reconciliation
Every booking can flow into TRI, which tracks revenue, supplier cost and margin per supplier in real time with FX-locked accounting.
API conventions
- REST over HTTPS, JSON in and JSON out.
- Authentication with an API key in the
Authorizationheader. - Standard HTTP status codes, paginated list responses and one consistent JSON error envelope.
- Sandbox access, your environment's base URL and the full endpoint reference issued at onboarding.
How an integration project runs
- Scoping. Which suppliers, which markets, which booking flows (search only, book, ticket, after-sales) and whether you hold your own contracts.
- Route choice. TripGic, ReservationHub, your own credentials, or a mix — decided per supplier.
- Credentials and certification. Supplier accounts and any certification steps they require; connections already live on our platform are configured, not rebuilt.
- Sandbox testing. Your team tests against sandbox access before anything touches live inventory.
- Go-live and monitoring. Production credentials switched on, with support from our engineering team.
Frequently asked questions
What is travel API integration?
Travel API integration is connecting a booking system to the programming interfaces of travel suppliers — GDS networks, airline NDC and low-cost carrier systems, bed-banks and ground-service providers — so it can search, price, book, ticket and service their inventory automatically. The hard part is not the first search call but normalising different formats, fare rules and booking lifecycles into one consistent workflow.
Should I integrate suppliers one by one or use an aggregator API?
Direct, one-by-one integrations give you full control but each one has to be built, certified and maintained. An aggregation layer such as TripGic gives you many suppliers through one REST API with a single data model. Many businesses combine both: the aggregator for breadth, with their own GDS or airline credentials plugged in where they already hold contracts.
Can I use my own GDS and supplier contracts?
Yes. ReservationHub connects to Amadeus, Sabre and Travelport using your existing credentials (PCC, Office ID or SID), so your commercial agreements, fares and ticketing authority stay yours. GDS and airline ticketing generally require your own IATA accreditation or a host arrangement; we tell you during scoping which connections need your own agreement.
How does the TripGic API work technically?
It is a REST API with JSON requests and responses. Authentication is an API key sent in the Authorization header, list responses are paginated, and errors come back in a consistent JSON envelope. Sandbox access, the base URL for your environment and the full endpoint reference are issued during onboarding. See the developer documentation for the conventions and a representative call.
Do you only provide search, or the full booking lifecycle?
The full lifecycle. In ReservationHub, bookings can be ticketed and serviced afterwards: PNR import, transfer, void, refund and reissue run as single actions, and an integrated GDS terminal with native cryptic commands is available beside the booking screens.
How long does an integration project take?
It depends on how many suppliers you need, whether they are already connected on our platform, and how quickly supplier credentials and certifications are issued. Connections we already run are configured rather than built. We give you a scoped timeline in the written proposal rather than a generic estimate.
How is it priced?
TripGic is usage-based and volume-tiered; ReservationHub depends on deployment model (SaaS, source code or API) and the suppliers you connect. Proposals are quoted in US dollars. Send us your supplier list and expected volumes for a quote.
