Booking.com API integration company
You connect to Booking.com or Expedia to sell their inventory on your site or stream your own rooms to theirs automatically. Either way, managing approvals, content feeds, taxes, and payment models is complex. COAX Software is a Booking.com API integration company that connects the APIs and keeps them stable.
Industry leaders we work with
Where our Booking.com API integration work starts
Booking.com rooms on your own site
Approved affiliate and demand partners can search Booking.com inventory, show property content, and send travelers to book, all inside a design that looks like your brand.
Expedia Rapid inventory in your checkout
Shopping, price checks, booking, and booking management connect through Expedia Rapid, so travelers book Expedia-supplied rooms without leaving your platform.
Your rates and availability pushed outward
For hotels, groups, and channel tools, availability and prices flow from your PMS or booking engine to Booking.com and Expedia the moment they change. Nobody updates extranets by hand anymore.
Reservations that come home on their own
New bookings, modifications, and cancellations land in your PMS and CRM automatically. Guest messages go out through HubSpot or Freshchat as soon as something changes.
Heavy content made light
Property feeds bring thousands of photos, amenity lists, and policy texts. We store, compress, and index them, add map search with Mapbox, and keep pages quick on a phone.
Taxes, fees, and payment models that add up
Net and gross prices, VAT, city taxes, and resort fees are calculated so your totals match what the OTA reports. Expedia Collect and Property Collect bookings each follow their own payment path.
Partner review preparation
Both companies review integrations before live traffic starts. We prepare test bookings, screenshots, and logs that show your flows meet their requirements.
Alarms before something goes quiet
Failed rate pushes, mapping errors, and price mismatches trigger alerts. Problems get fixed before a sold-out room stays open on an OTA.
Pick your side of the connection
First we confirm whether you’re selling OTA inventory, sending yours out, or both.
- That decides which programs and APIs apply.
- It also shapes the whole plan.
Deliverable: integration direction brief
Line up access
Partner applications and credentials go through your company’s accounts.
- We help prepare the information each program asks for.
- Approval timelines get built into the schedule.
Deliverable: access checklist, program requirements summary
Map rooms, rates, and rules
Room types, rate plans, taxes, and cancellation policies are matched between systems.
- Payment models get settled for every rate.
- Mismatches are fixed on paper first.
Deliverable: mapping sheet, pricing and tax rules
Build and rehearse in the sandbox
Every flow is built against test environments.
- Edge cases get tested on purpose: overbooking attempts, last-minute changes, partial cancellations.
- You click through the real sequence each sprint.
Deliverable: sandbox-ready integration, test log
Clear the partner review
Test bookings and evidence go to the OTA’s review team.
- Feedback is turned around quickly.
- Live credentials are stored securely.
Deliverable: review package, production configuration
Watch the pipes
Rate pushes, reservation pulls, and error rates are monitored.
- API changes from either OTA are tracked and handled ahead of time.
- New properties or markets plug into the same setup.
Deliverable: monitoring dashboard, maintenance schedule

Why hotels and travel sellers pick us as their Booking.com API integration company
Fluent in both directions of hotel distribution
On Stay Altered, our engineers connected Katanox and HyperGuest to bring live hotel inventory into one platform. The same thinking applies whether rooms flow toward you or away from you.
No more midnight copy-paste
Reservations, changes, and cancellations arrive in your systems on their own. Front desks and sales teams get back the hours they spent retyping OTA bookings.
Totals that match the OTA’s invoice
Taxes, fees, commissions, and payment models are calculated the same way on both sides. Month-end reconciliation stops being a hunt for missing euros.
A connection you can unplug and replace
Each OTA sits behind its own adapter, and the code belongs to you. Add a channel, pause one, or switch partners without rebuilding your platform.
FAQ
COAX Software does. We connect platforms that sell Booking.com or Expedia rooms, and hotels or channel tools that send their own rates out and pull reservations back. Our engineers already maintain live hotel integrations with Katanox and HyperGuest.
For a single property or a small group, an existing channel manager is often the simpler route. A direct connection makes sense if you’re building your own PMS, channel tool, or a platform serving many properties. We’ll help you weigh both against your size and plans.
COAX Software provides them as a Booking.com API integration company covering content, availability, reservations, taxes, and partner reviews. Every engagement starts by confirming which Booking.com program fits your business.
Look for a team that already runs live hotel distribution integrations and understands rate mapping, tax handling, and partner certification. COAX Software fits that description, with Katanox and HyperGuest connections serving 170+ properties across 45+ countries.
COAX Software can. We build the API integration Booking.com expects from its partners, then shape search, booking, and post-booking flows around your product. Expedia Rapid can be added through the same adapter layer.
With Expedia Collect, Expedia takes the guest’s payment, and the property is paid later, often by virtual card. With Property Collect, the guest pays the hotel directly, usually at the time of stay. Your platform needs to handle both correctly, and we build each payment path separately.
The best choice is a team that asks which side of distribution you’re on before it quotes, has hotel APIs running in production, and is honest about partner approval timelines. COAX Software works that way and backs it with ISO/IEC 27001 and ISO 9001 certification and a 4.9/5 Clutch rating.
