Introduction

A leading online travel company required faster innovation cycles and scalable integrations to meet rising customer expectations. Existing workflows for flights, hotels, and subscription-based services were fragmented, reliant on third-party APIs, and prone to inefficiencies. The organization needed to enhance system performance, reduce dependency on external providers, and deliver a more seamless booking experience across channels

• Integrate multiple flight suppliers and ensure accurate transformer rules for pricing, booking delays, and add-ons.

• Build scalable loyalty and subscription services (Prime) with personalization and benefit-tracking.

• Replace reliance on external APIs (Google Hotel Pull API, deduplication) with in-house services.

• Enable accurate, real-time hotel pricing and reduce vendor duplication.

• Automate support workflows, improve monitoring, and enhance customer experience.

• Leverage a modern tech stack and cloud-native approach for scalability and faster rollouts.

Flights

• Integrated SABRE and Akasa suppliers into the booking system.

• Enabled insurance, promo code, meal & seat integrations across web and mobile.

• Enhanced transformer rules for complex pricing and deployed price-delay and multi-ticket configurations.

• Added Skyscanner visibility, auto seat selection, and multi-currency (AED, NZD) support.

• Provided daily monitoring and ongoing product support.

Prime (Loyalty & Subscription)

• Delivered core services: registration, personalization, usage & consumption tracking.

• Implemented scheduler service and integrated soft lock with SSO tokens. Migrated customer data from legacy MO to Prime DB.

• Launched PrimeLite plan, WhatsApp notification service, and failure analysis reports.

Hotels

• Built Hotel Price Ads (HPA) feature using a push API to replace Google's pull API for real-time prices.

• Developed a deduplication engine using Elasticsearch fuzzy matching to eliminate vendor duplicates.

• Progressed Amadeus SOAP endpoint integration to enrich data and inventory.

 Technological Framework

Why these technologies?

Java 8 with Spring Data JPA delivers reliable, transactional booking logic, while MERN and Angular provide the responsive front-end needed for complex multi-supplier flight search and booking flows.

Why these tools?

Spring Boot microservices enable independent scaling of Prime and Hotel services, while Kafka handles the event-driven price updates and deduplication signals needed for real-time hotel pricing accuracy.

Why this Setup?

Standardised supplier integrations via SABRE, Akasa, and Amadeus SOAP ensure consistent booking accuracy, while WhatsApp and SSO integrations deliver the seamless, connected experience customers expect.

Takeaway

Zapcom delivered improved booking accuracy, real-time hotel pricing, and cloud-ready microservices architecture reducing third-party API dependency and enabling faster rollouts across flights, hotels, and loyalty.
