Contact us

Improve travel experiences with effortless API connectivity. Users demand access to everything in one place: an online travel agency. With our travel and hospitality API development services, you give them a one-stop-shop for amazing experiences.

What we offer with our custom API integration services

Tour API

Online travel providers use tour APIs to let users track events, check details, and complete bookings inside one flow with no redirects or fragmented tools. We integrate these into platforms where activity and experience booking are alongside flights and accommodation, keeping the entire journey in one place.

Transfers API

Transfer APIs are a way to integrate ground functionality with your travel business goals. You can integrate all software products for all in-demand travel tools for consolidated flights, hotels, transport, and tour bookings.

Flight API and flight price API

Flight APIs pull live schedules, seat maps, and availability, while flight price APIs fetch real-time fares across all channels. Together, they ensure every search, booking, and post-purchase update returns instant, accurate results, whether your platform serves airlines, aggregators, or travel agents managing mixed itineraries.

Cruise API

You can simplify cruise bookings with unified booking platform APIs that pull availability, cabin options, and pricing. OTAs and travel agencies use this to automate bookings and cut the manual coordination. From luxury liners to expedition voyages, you can automate reservations and streamline operations.

Accommodation and hotel search API

Accommodation APIs bring global lodging inventory (hotels or vacation rentals) into any platform with availability and property data updated in real time. Hotel API integration for search powers dynamic filtering by location, dates, price, ratings, and amenities for metasearch engines, travel apps, and loyalty programs.

Hotel booking API

With hotel booking API integration, you connect to thousands of properties and automate the full reservation cycle with instant confirmations and cancellations. We applied this for Re:Plan's hotel resale marketplace. Built for OTAs, corporate systems, and travel agencies that need reliable hotel APIs at scale.

Hotel payment API and gateway

Payment APIs give agents and users access to virtual cards, wallets, and transfers across all booking channels. We integrate APIs and gateways that help process payments with credit cards, digital wallets, and BNPL, as we did for a guided trip booking system that needed travel booking API integration to keep every transaction compliant.

The key benefits of travel portal development and integrating APIs

Travel API features

  • Centralized dashboard

    COAX can integrate feature-rich central online reservation systems and micro-services-based APIs. You can administer everything from a central dashboard available through an easy-to-use interface, where you can manage complete inventory, customer service, and rich content.

  • Booking widgets

    From hotel booking API integration to all-around tour bookings, we implement travel software solutions with booking widgets to inquire about the availability of different services at diverse locations, make reservations, and track the progress of booking requests.

  • Accommodation search & booking

    Travel API integration services create a functionality for checking live availability, comparing room rates across seasons, viewing property information, and completing bookings. For operators, it also offers centralized management of inventory, rates, and reservations.

  • Online travel portal

    Travel portal development is a way for tour operators, travel agencies, and travel companies to sell travel packages and generate more bookings. COAX developers can create a custom travel portal tailored to the needs of both travel agents and individual users.

  • Manage listings and content

    With API integration, you can access and manage destination content from traditional and new sources, including flights, hotels, transportation, and event updates. Your customers can find their preferred suppliers, travel options, holiday packages, and price comparison quickly.

  • Security and scalability

    You can trust our experienced team to integrate the best-in-class travel APIs that are secure and tailored to accommodate your growth and user demands. Everything from user data to payment details remains end-to-end encrypted and scalable for an enhanced reservation flow.

Our development process

We pull apart everything touching your reservation flow, all the tools, the handoffs, and the places where a human steps in because the system can't. We put down supplier contracts, channel setups, and user needs. Everything gets confirmed in writing before we move.

Stack choices, integration priorities, and feature sequencing all get decided here with your input. We weigh what brings the most value earliest, whether that's booking platform APIs, payment logic, or inventory connections, and build a phase plan around that order.

Screens get designed logically: we set exactly what a dispatcher needs, what a traveler needs at step two of checkout. Role-specific views, logical flows, zero decorative complexity. Every screen comes back to you for feedback before a single component is created.

Each sprint produces something you can click through and test. Travel booking API integration, live feeds, payment routing, supplier handshakes all land in working increments, not in one delivery at the end that surprises everyone.

We break it before your users do. Concurrent sessions, rate shifts mid-booking, gateway timeouts, and inventory conflicts at peak load get staged and resolved. Results are logged so that nothing ships with an open issue attached to it.

The system keeps getting better after go-live. Performance stays monitored, patches go out in low-traffic windows, and new supplier connections or booking types slot in cleanly. What works stays untouched, and what needs to grow, grows.

Client feedback


I was most impressed by the quality of the end product.

While my ideas formed the basis for the work, they delivered a far more superior product than I imagined with greater flexibility and viability of features. They exceeded expectations so many times it got to the point I couldn't wait to see what they came up with next.

Dan Brooks

President, Krytter

I implicitly trust the whole COAX team to do the right thing by location:live, and to have blunt and honest conversations with me when we are in the thick of delivery. COAX are the engine room and compass behind our market-leading tech.

Frequently asked questions and answers

A travel API is a way for software applications to communicate with each other so that you can get the best possible travel deals. This interface allows travel suppliers (such as flight reservation providers, hotel booking engines, and car rental companies) to consolidate their various products into one easy-to-use interface. This means you can access various travel options from one place, and the experience will be more efficient and convenient than ever before.

Integrating a travel API into your website or application can give you access to a wider range of travel options, real-time availability and pricing, improve user experience through a seamless booking process, and reduce development costs and time by leveraging the functionality of an existing travel service provider. So while your software becomes a one-stop platform for all travel solutions, your workflow gets more efficient, and your customers are better satisfied, you're also saving overhead costs on maintenance, updates, and development of legacy software with such advanced functionality.

When considering third-party APIs, the extent of customization can vary for each platform. Some travel APIs may offer customization options, while others may not. Custom API development is always an option if you aren't satisfied with an existing API. Contact our experts, so we can learn more about your specific needs and answer with more accurate information to make API customization profitable for you!

Hotel API integration connects your platform to global hotel databases, allowing real-time access to room availability, pricing, and booking capabilities. It works by fetching live data from suppliers, so users can search, compare, and book accommodations instantly.

A travel booking API saves time and costs by providing ready-made access to flights, hotels, and other services. It handles complex tasks like real-time pricing, inventory updates, and secure payments, so you can focus on improving user experience rather than backend development.
