GDS API Integration
NDC API Integration
Low-Cost Carrier (LCC) APIs
Airline APIs and Aggregators
We deliver the deepest integration of GDS APIs with the major brands, such as Amadeus API integration, Sabre API integration, and Travelport API integration. Through these integrations, global airline inventories, fare rules, seat availability, and automated ticketing workflows can be accessed, which are the workflows of enterprise travel platforms.
Our NDC API integration enables direct connectivity to the airline, the distribution of rich content, and new pricing models. It offers management, order creation, and content normalization that we take care of while also aligning the NDC flows with existing GDS logic if necessary.
By directly connecting with APIs of low-cost carriers (LCC), travel platforms gain the opportunity to pick up competitive, low prices and have a red-carpet, simplified booking service flow, thus increasing their range of routes and price flexibility.
Based on your coverage strategy, we can accommodate direct airline APIs and aggregator-based models, thus providing the possibility of multi-API flight integration with smart fallback logic.
Connect airlines, compare fares, and book faster with a single API.
Discuss project goals, scope and expectations with the client to ensure a clear understanding.
Define the scope and design a scalable and secure architecture based on the project’s needs.
Write clean, standard code and test the project’s features through unit and integration tests.
Frequently review the code, then deploy the app using CI/CD pipelines.
Monitor the performance of APIs and implement changes or new features as needed.
OneClick offers fast, secure, and scalable flight booking API integration for OTAs and travel platforms. From real-time availability to multi-GDS support, we help you go live quickly with global coverage.
First, we analyze your business objectives, target markets, and booking workflows. The outcome of this step is identifying the most suitable airline, GDS, or NDC APIs and setting up an integration approach that meets your operational and scalability requirements.
We make sure that both sandbox and production environments are configured in such a way that API authentication, credential management, and permissions are secured, regulated, and compliant with the standard for stable connectivity.
We use proven custom flight API integration methodologies to implement the functions that you require in your platform, such as flight search, pricing logic, PNR creation, ticketing and booking, cancellations, refunds, and any other business-specific rules.
To validate data accuracy, reliability, and API error handling, and also to check effective API rate-limit management under the very high traffic conditions, we carry out extensive testing of the API.
We do continuous monitoring, performance tuning, updating, and long-term post-integration support after deployment, thus ensuring smooth scaling and uninterrupted operations.
Integration Challenges We Solve
Credits and availability are among the aspects that are often mismatched between fare search and booking results. Also, discrepancies often arise between the bank involvement and bank sales, as well as with bank fees; both of these cases are allowed in the bank because of internal policies.
GDS, NDC, and airline content inconsistencies are standard issues most of the time. Different APIs return data in varying formats and structures. We do content normalization across the GDS API integration, the NDC API integration, and the airline APIs to get uniform results and a smooth booking process.
Conversion rates get negatively affected as a result of high response times. In order to enhance speed and keep up the performance during high traffic times, we make the API calls, caching strategies, and backend workflows more efficient.
These are some of the issues we solve through the implementation of secure APIs, error handling, try mechanisms, and methods to recover from failure to reduce wrong booking transactions and improve booking stability.
This is a challenging task when managing multiple airline and aggregator APIs. We create intelligent multi-API integration layers that come with smart delivery and failover support features.
Booking Combination
In the case of flight booking API integration, we do not only link your portal and global airlines—we help you construct full, modular travel booking ecosystems. Whether you're designing a B2B flight booking portal, an OTA platform, or a custom mobile app, our team uses APIs in even more inventive ways to create enhanced services that help cultivate travel bookings. By integrating flight booking engine API with other services like hotels, transfers, and tours, you will allow your travel platform to be much more than an air flight finder, you will have a complete trip planning tool.
Depending on the type of API (GDS, LCC, aggregator) and the complexity of your platform, it can take anywhere from 2-6 weeks.
Yes. We regularly design multi-source search engines, merging results from multiple APIs, such as Sabre + TravelFusion or Amadeus + LCC APIs.
Yes. We offer both customized builds and white-label. Your branding, markup engine and business rules can easily be included.
For back-end we typically use Node.js and MongoDB, for front-end React.js or Angular and we integrate payment gateways like Stripe, Razorpay or PayPal.
Yes, for any payment processing features, we follow strict PCI-DSS standards to ensure user data and transaction safety.
Absolutely, we provide multi-language and multi-currency modules to serve global customers.
Real-time flight booking API integration enables your travel platform to access current flight schedules, seat availability, prices, and immediate booking confirmations across multiple airline services. Key components are secure authentication, connectivity to GDS or LCC API services, multi-currency and multi-language support, caching for performance, and dynamic pricing.
An example of the flight booking API integration steps could look something like following flow:
Choose a suitable API provider (GDS, LCC, or NDC).
Get your API keys and documentation.
Setup secure endpoints and authentication processes.
Integrate the APIs for flight search, availability, and booking into your travel agent or agency platform.
Test it by using staging credentials.
Go live once outlet has completed UAT (User Acceptance Testing) and airline has completed compliance.
By connecting your system to several global distribution systems (Amadeus, Sabre, Travelport, etc...) Multi-GDS API integration enables users to access a wider range of airlines, routes, and offers. The benefits of implementing a Multi-GDS API integration are as follows:
Larger flight inventory
More competitive fare ranges
Support for both international and low-cost carriers
Higher booking success rates
NDC (New Distribution Capability) API integration allows travel platforms to connect directly to airlines, using XML communication flows defined by IATA. This enables travel partners to bypass GDSs (Global Distribution Systems) using the airlines own XML standards to get access to personalized fares, seat maps, ancillary services, and upsells all available in the travel platform's booking interface.
NDC API integration can distinguish your travel platform through:
Direct connections to airlines (no middle layer)
Personalized pricing and offers
Access to bundled offers (seats, meals, baggage)
Faster response times
Improved customer experience and upsell opportunities
LCC (low-cost carrier) airline API integration connects your booking platform directly to low-cost airlines such as Ryanair, IndiGo, AirAsia, and many others. It is substantial for:
Identifying low-cost, price affected travelers
Broader flight options with regional, low-cost carriers
Providing mixed itinerary options with GDS and non- GDS airlines.
