Amadeus GDS Gateway: Enterprise Travel Data Orchestration
Massive enterprise GDS integration with 2559+ service modules, Redis caching, JWT authentication, and XML/JSON transformation for travel inventory aggregation.
Project Overview
The Challenge
Amadeus GDS provides 1000+ travel services but uses legacy SOAP/XML protocols incompatible with modern microservices architectures, creating a massive integration challenge.
Direct Amadeus API calls are expensive (cost per transaction), making it financially unfeasible to query in real-time without intelligent caching.
Multiple white-label travel platforms needed secure, isolated access to the same Amadeus integration without cross-contamination of customer data.
Lack of comprehensive documentation made it difficult for development teams to understand which Amadeus services to use for specific business requirements.
Architected a comprehensive Amadeus Global Distribution System (GDS) integration serving as the central gateway for hotel, flight, and car rental inventory. Built as a microservices-oriented application with 2559 service files, representing one of the most complex integration projects in the travel technology stack.
Implemented sophisticated caching strategies using Redis (ioredis) to reduce GDS API call costs by 60%, storing frequently-accessed travel data with intelligent TTL policies. Integrated JWT-based authentication with Passport.js for secure B2B API access, supporting multiple white-label travel platforms.
Developed bidirectional XML-JSON transformation pipelines to bridge legacy SOAP-based Amadeus APIs with modern RESTful consumers. Built custom Swagger documentation covering 150+ endpoints, making the complex GDS functionalities accessible to frontend and integration teams.
Technical Architecture
Authentication Layer: JWT-based access control with Passport.js, enabling multi-tenant isolation for white-label platforms sharing the same infrastructure.
Massive Service Library: 2559 service files organized by domain (hotels, flights, cars), each implementing specific Amadeus API capabilities with standardized interfaces.
Intelligent Caching: Redis stores frequently-accessed data (city codes, airport info, rate rules) with configurable TTLs, reducing Amadeus API costs by 60%.
Protocol Bridge: Bidirectional XML-JSON transformation using xml2js and xmlbuilder, allowing modern REST clients to consume legacy SOAP services seamlessly.
Observability: Comprehensive logging with morgan-body and email alerts for critical errors, enabling rapid troubleshooting in production.
Key Challenges & Solutions
Mastering 2559+ Service Integration Points
Organized services into logical modules (hotels, flights, cars, cross-domain) with consistent patterns for error handling, caching, and transformation. Created internal documentation Wiki mapping business requirements to specific Amadeus services.
Cost Optimization Through Caching
Implemented Redis caching with intelligent TTL policies: static data (airports, cities) cached for 30 days, dynamic data (availability) for 5 minutes. This strategy reduced Amadeus API costs by 60%, saving significant operational expenses.
XML-JSON Transformation At Scale
Built reusable transformation utilities handling Amadeus' complex nested XML schemas. Created schema validation to ensure transformed JSON maintains data integrity, preventing booking errors from malformed payloads.
Multi-Tenant Security Architecture
Designed JWT authentication system with tenant-specific scopes, preventing data leakage between white-label platforms. Each tenant's API keys and search history are cryptographically isolated.
