Travel platforms across the world need real-time access to flights, hotels, and other essential services.
Most of the services are powered by GDS (Global Distribution Systems) such as Amadeus, Sabre, and Travelport.
Still, it is not very easy to merge GDS systems with the latest booking platform.
In contrast to today’s cloud-native, REST/JSON-driven front-end applications, GDS APIs often rely on outdated XML/SOAP protocols, rigid schemas, and complex request/response cycles.

Why GDS-to-Booking Platform Integration Is Challenging
Before exploring how MuleSoft solves the challenge, it’s important to understand the integration pain points:
1. Different Communication Protocols
GDS systems often rely on SOAP/XML interfaces, while booking engines typically prefer REST + JSON for speed and flexibility.
2. Complex Multi-Step Workflows
Flight or hotel booking is not a single API call – it includes:
- Flight search
- Fare validation
- Seat availability
- Pricing confirmation
- PNR creation
- Ticket issuance
- Post-booking changes/cancellations
Each step may touch multiple systems.
3. Normalising Data From Multiple Sources
If a travel platform integrates two GDS systems simultaneously (e.g., Amadeus + Sabre), data formats differ. Without normalisation, the front-end becomes messy and inconsistent.
4. Real-Time Inventory and Updates
Travel demand fluctuates rapidly. Integrations must handle large volumes of traffic with minimal latency.
5. Handling Legacy Systems
Some suppliers or airlines still use legacy host environments or on-prem systems making integration even more complicated.
MuleSoft addresses all these challenges through its modern, layered, API-led architecture and HashStudioz delivers the expertise to implement it effectively.

How MuleSoft Bridges GDS Systems With Modern Booking Platforms
HashStudioz’s MuleSoft Integration Services page emphasises the following core strengths:
- API-led connectivity
- Legacy system modernisation
- Hybrid cloud integration
- Reusable integration assets
- Real-time data sync
- End-to-end automation
- Secure, governed API ecosystem
All of these capabilities map perfectly to GDS integration. Let’s break down how MuleSoft actually connects Amadeus, Sabre, and other GDS systems to booking platforms:
1. API-Led Connectivity: The Backbone of GDS Integration
MuleSoft uses a structured, three-layered API-led architecture that simplifies complex GDS workflows:
a) System APIs – Wrapping GDS Interfaces
System APIs communicate directly with GDS systems without exposing complexity to the booking engine.
HashStudioz uses MuleSoft to:
- Wrap SOAP/XML GDS endpoints into stable, reusable APIs
- Standardise authentication and session handling.
- Avoid direct integration between the booking engine and GDS.
Thus, the booking platform never interacts with the GDS directly; it only communicates with clean, modern System APIs.
b) Process APIs – Orchestrating Travel Workflows
These APIs combine different GDS services to form logical business processes.
For example:
“Flight Search Process API” → integrates:
- Amadeus shopping API
- Sabre multi-fare search
- Additional airline APIs (optional)
HashStudioz uses MuleSoft to orchestrate:
- Fare comparison
- Seat mapping
- Tax calculation
- Booking confirmation
- PNR management
- Cancellation workflows
These complex flows become modular, reusable processes.
c) Experience APIs – Delivering Clean Data to UI/Front-End
Experience APIs expose data in the format your booking platform needs fast, lightweight, JSON-based services.
This enables:
- Web portals
- Mobile apps
- B2B agent portals
- Affiliate/white-label channels
Each experience API can be personalised without changing the underlying GDS interfaces.
2. Hybrid Integration: Handling Legacy + Cloud Systems Together
HashStudioz’s MuleSoft services highlight the ability to integrate on-premise and cloud-based systems seamlessly.
This matters because:
- GDS systems may run on legacy infrastructure
- Booking engines generally run on cloud platforms like AWS/Azure.
- Payment gateways, CRM, ERP, and user management are modern cloud services.
MuleSoft supports:
- On-prem GDS connectivity
- Cloud-based booking engine integration
- Secure communication tunnels
- High availability and load balancing
This gives travel platforms a unified integration layer without forcing infrastructure changes.
3. Data Normalisation Using DataWeave
Every GDS returns its own data structure. MuleSoft’s DataWeave engine – part of HashStudioz’s integration toolkit – standardises:
- Airline codes
- Fare classes
- Seating info
- Ancillary services
- Tax breakdowns
- Ticketing details
This ensures your booking engine receives clean, unified, predictable data regardless of the GDS source.
4. Automation of Multi-Step Booking Workflows
Travel booking is not a single API call, it’s a chain of dependent operations.
HashStudioz leverages MuleSoft to automate:
- Price & availability checks
- PNR creation
- Holding reservations
- Payment initiation
- Ticket issuance
- Notifications & email alerts
- Post-booking modifications
This eliminates manual handling, reduces errors, and ensures a seamless user journey.
5. Highly Scalable, Reusable Integration Assets
GDS integration is not a one-time project. Over time, you may want to add:
- More airline APIs
- Hotel aggregators
- Car rental providers
- Dynamic packaging engines
- Loyalty programs
- Currency management
HashStudioz uses MuleSoft to create reusable connectors and API templates so new integrations can be plugged in easily without rewriting code.
6. Secure, Governed API Ecosystem
Since booking systems work with payments and personal travel data, security is crucial.
HashStudioz uses MuleSoft Anypoint Platform features such as:
- API Gateways
- Role-based access control
- Threat detection
- Encryption & tokenization
- Secure logging & monitoring
- Compliance with data regulations
This means the entire GDS → API → booking portal pipeline remains safe and auditable.
