About AOPAY Flight API
What is the AOPAY Flight Booking API?
AOPAY's Flight Booking API is a unified, cloud-native travel technology layer that connects your platform to the complete airline ecosystem — GDS (Global Distribution System), NDC (New Distribution Capability), and Low-Cost Carrier (LCC) direct feeds — through a single, well-documented REST API.
Built for OTAs, TMCs, corporate travel platforms, travel startups, and super apps in India, AOPAY abstracts the complexity of multi-source airline content aggregation, PNR lifecycle management, fare rule handling, and compliance reporting into clean, developer-friendly API endpoints that your engineering team can integrate in days — not months.

Why AOPAY
Why India's Travel Platforms Choose AOPAY Over Amadeus, Sabre & Travelport
Legacy GDS vendors were designed for large airlines and global travel enterprises — not for agile Indian travel startups, OTAs, or corporate travel platforms that need speed, flexibility, and transparent pricing. AOPAY changes that.
GDS + NDC + LCC in One API
No need to maintain separate integrations for GDS, NDC, and low-cost carriers. AOPAY normalizes all content into one unified API response.
Developer-First REST Architecture
Modern REST JSON APIs with full documentation, Postman collections, SDK libraries, sandbox access, and code samples — no legacy XML complexity.
India-First Pricing & Support
Transparent per-request pricing designed for Indian travel market realities, flexible plans for startups, and a dedicated India-based support team.
Weeks to Integrate — Not Months
AOPAY's clean API design and comprehensive documentation reduce integration timelines from the 3–6 months typical with legacy GDS vendors to 1–3 weeks.
Modular API — Pay for What You Use
Activate only the modules you need — search, booking, ancillaries, cancellations, reporting. Scale individual modules as your platform grows.

★★★★★ 4.9/5 from 820+ developer reviews
“AOPAY's flight booking API documentation is the best I've seen from any travel API vendor in India. We went from sandbox to production in 18 days. The GDS+NDC unified response saved us building a separate aggregation layer entirely.”
Arjun Mehta

Priya Kapoor
VP Engineering - CorpTravel360 · Delhi

Rohan Sinha

“AOPAY's cancellation and refund API was a game-changer during COVID. Automated refund processing across thousands of bookings without any manual intervention. The webhook-based status updates kept our customers informed in real time.”
