Travel APIs
What is a travel API?
A travel API connects a company to sell or display travel inside its own product, using another company's inventory, rates, and booking infrastructure. Ours carry the same supplier contracts and member-only rates behind the CTS platform, so you can put travel in your app, member portal, or rewards hub without building any of it.
One contract, one connection, and the same inventory that runs our own platform.
-
01
ONE CONNECTION
Five travel categories through a single integration, not five vendor relationships.
-
02
MEMBER RATES
The same closed user group rates behind our platform, priced for your program.
-
03
RUN FOR YOU
Supplier contracts, payments and 24/7 member support handled on your behalf.
Five APIs, one connection
Take one category or all five. They share a contract, a connection and a booking model, so adding another later is not a project.
-
01
Hotels API
Hotels
3M+ properties, including closed user group rates that are not published on public sites.
-
02
Flights API
Flights
Full-service, low-cost, and regional carriers priced together in one search.
-
03
Car Rentals API
Car rental
Major and regional suppliers worldwide, bookable alongside the rest of the trip.
-
04
Activities API
Activities
Tours and things to do at the destination, which keep members engaged after arrival.
-
05
Vacation Rentals API
Vacation rentals
Whole-home stays for members traveling as families or in groups.
Cruises and tickets are part of the full platform rather than the API set, so if your members need those, the platform is the route.
Three ways to get CTS travel
The inventory is the same in all three. The difference is how much you want to build.
-
01
Full platform
Who it fits
You want to live without a development project, or you need cruises and tickets.
White-Label Travel PlatformWhat you own
Your brand and your members. We build, run, and support the program.
-
02

Who it fits
You have a product and a team, and travel belongs inside it.
What you own
The interface and the member experience. We supply inventory, rates, and fulfillment.
-
03
RouteStack.ai
Who it fits
You have an AI assistant and want members booking travel in conversation.
RouteStack.aiWhat you own
Your assistant and your members. We supply the travel layer behind it.

What sits behind the connection
The APIs carry the same supply as our own platform: direct supplier contracts rather than a resold feed, closed user group rates, and depth well beyond the main tourist cities. That is what makes the rates worth putting in front of your members.
- Direct supplier relationships, not a resold feed
- Member-only rates you cannot get from a public booking site
- You set the margin on every category
- Optional merchant of record, so you can earn without taking payment liability

Questions, answered
Frequently Asked Questions
What is a travel booking API?
A travel booking API lets your product search, price and book real travel inventory through another company's supplier connections. Your members book inside your app, and the fulfillment, payments and support happen behind it.
Can we get cruises and tickets through the API?
Not today. Those categories run through the full platform rather than the API set. If your members need them, the platform is the route, and we can talk through what that looks like alongside an API integration.
Do we have to take all five APIs?
No. Take one category or all five. They share one contract and one connection, so adding another later is a configuration, not a new integration.
Who supports our members when a booking goes wrong?
We can, in your name, 24 hours a day, across chat, phone, email, and WhatsApp.
Member SupportWho handles payment?
Your choice. We can act as merchant of record and handle billing, or you can keep payments in-house with your own processor.
How long does integration take?
It depends on what your team is building, not on us: the connection and the inventory are ready on day one. A scoping call is the fastest way to get a realistic timeline.
