GDS API Integration Services for Scalable Travel Platforms

Expandorix is a specialist GDS integration company helping travel agencies, OTAs, DMCs and B2B travel platforms connect seamlessly with the world's leading Global Distribution Systems. Whether you need Amadeus API integration, Sabre GDS connectivity or Travelport API access our engineering team delivers fast, reliable and production ready GDS API integration services built to scale.

From real time flight search and fare calculation to automated ticketing and mid office synchronisation we handle the full complexity of GDS software development so your team can focus on growing the business.

What is GDS API Integration?

A Global Distribution System is a computerised reservation system which serves as a central access point for airlines, hotels and car rentals and other travel services. GDS API integration links your travel platform to these systems that allow access to real time inventory, real time prices, real time booking confirmation and real time automated ticketing.

The three dominant GDS platforms, Amadeus, Sabre and Travelport collectively power the majority of the global travel booking ecosystem. Integrating your platform with one or more of these systems is not optional for serious travel businesses; it is the foundation of a competitive booking engine.

In the absence of a strong GDS integration service travel portals can only offer manually managed fares, as well as sluggish availability information, and disconnected booking processes. It comes with a live pipeline to hundreds of airlines, thousands of hotels and global travel inventory updated in milliseconds.

Why GDS Integration is Critical for Your Travel Business

The travel industry runs on real-time data. A one-second delay in fare availability or a missed seat confirmation can cost a booking and a customer. Here is why travel businesses across the globe rely on expert GDS API integration:

• Access to real time flight inventory from 400+ airlines via a single API connection
• Live pricing with fare rules, baggage policies and seat availability
• Instant booking confirmation and automated e ticket issuance
• Seamless B2B and B2C booking flows across web and mobile
• Support for NDC (New Distribution Capability) alongside traditional GDS content
• Integration with mid office and back office systems for operational efficiency
• Multi currency and multi language support for global markets
• Compliance with GDS provider certification standards

GDS Platforms We Integrate

Amadeus API Integration

Amadeus is the largest GDS by market share powering travel agencies and OTAs across Europe, Asia and the Americas. Expandorix provides full Amadeus API integration including the Amadeus Self Service APIs and the Amadeus for Developers platform. Our integration covers flight search, pricing, booking, seat selection, ancillary services and ticketing. We also support the Amadeus hotel and car content APIs for multi product platforms.

Sabre GDS Integration

Sabre is the preferred GDS for North American markets and one of the most widely deployed global reservation systems. Our Sabre API integration covers the Sabre Red 360 environment, SynXis for hotels, and the full Sabre Dev Studio API suite. Key capabilities include BargainFinder Max for fare shopping, Enhanced Air Book, and Sabre Web Services (SOAP/REST). We ensure proper PCCs, pseudo city codes, and Sabre certification processes are handled end-to-end.

Travelport API Integration (Galileo / Worldspan)

Travelport operates two major GDS systems Galileo and Worldspan along with its Universal API (uAPI). Expandorix delivers complete Travelport integration for flight, hotel, and car rental content. We work with Travelport Universal API (JSON and XML) to configure the right branch IDs and support full ticketing and voiding workflows. Travelport is particularly strong in EMEA and APAC markets, making it an ideal GDS partner for globally focused platforms.

LCC & Aggregator API Integration

Not all airlines are GDS-distributed. For low-cost carrier content Expandorix integrates third party aggregators and direct airline APIs including TBO Holidays, Tripjack, Travclan, AeroCRS and others. This hybrid approach ensures your platform covers the widest possible inventory combining GDS depth with LCC reach.

Our GDS Integration Services

Expandorix offers end-to-end GDS API integration services across the full booking lifecycle. Here is what we deliver:

Flight Search & Booking API Integration

We integrate advanced fare shopping engines capable of handling complex multi city searches, fare families, branded fares and availability caching. Our flight booking integrations cover round trips, one way and multi leg itineraries with real time availability and pricing.

Fare Rules, Ticketing & Void/Refund Workflows

Beyond search and booking, our GDS software development includes complete fare rule display, ticketing (PTA/XTA), ticket void, revalidation, and refund workflows — fully automated and mapped to your mid-office system.

Hotel & Ancillary API Integration 

We connect hotel supplier APIs alongside GDS hotel content — including Hotelbeds, RateHawk, and direct supplier connections — giving your platform a combined inventory of thousands of properties with real-time rates and availability.

Mid-Office & Back-Office Automation

GDS integration is not just a front-end function. Expandorix builds middleware layers that synchronise bookings, PNRs, and ticketing data with your back-office systems, CRM, accounting tools, and reporting dashboards — eliminating manual data entry and reducing error rates.

Payment Gateway Integration

We integrate secure payment gateways including Stripe, PayPal, Razorpay and global 3DS compliant solutions to complete the booking flow. Our payment integrations support multi currency processing as well as refund workflows and fraud prevention rules.

Multi-Supplier Aggregation

For platforms that need the broadest travel content we build unified API layers that aggregate multiple GDS systems and third party suppliers into a single search interface normalising response formats, deduplicating results and ranking fares intelligently.

• Protocols: REST/JSON, SOAP/XML, NDC (IATA 21.3+)
• Backend: Node.js, Python, Java, PHP
• Caching: Redis for fare caching and session management
• Cloud Infrastructure: AWS (EC2, Lambda, API Gateway), Google Cloud
• Security: OAuth 2.0, TLS 1.3, PCI-DSS compliant payment flows
• CI/CD: GitHub Actions, Docker, Kubernetes for scalable deployments
• Monitoring: Datadog, New Relic, custom alerting for API response times

Our GDS Integration Process

We follow a structured, milestone-driven process to ensure every GDS integration is delivered on time, within budget, and to GDS provider certification standards.

Discovery & Requirement Analysis

We begin by understanding your business model, target markets, supplier relationships and technical environment. This scoping phase defines the right GDS platform(s), integration approach and project roadmap.

Integration Architecture & Design

Our architects design the API workflow, caching strategy, failover mechanism and data models. We define the PNR management approach, session handling and middleware layer — ensuring the system is built for high availability from day one.

Development & GDS Certification

Our engineers implement the integration against GDS sandbox and test environments, followed by full certification with the GDS provider. This phase includes unit testing, regression testing, and load testing to validate performance under peak traffic.

Deployment & Go-Live

We manage the production deployment, configure monitoring, and ensure a smooth go-live. Our team runs parallel validation to confirm live GDS responses match expected behaviour before full traffic cutover.

Ongoing Support & Optimisation

Post launch Expandorix provides continuous monitoring, API version upgrades, performance optimisation and dedicated technical support. GDS providers regularly update their APIs to ensure your integration stays current.

Who We Serve

Our GDS integration services are trusted by travel businesses across multiple segments:

• Online Travel Agencies (OTAs) — B2C and B2B booking portals requiring full content GDS access
• Destination Management Companies (DMCs) — requiring multi supplier itinerary and flight booking
