THE TRAVEL API FROM ENGINE
The travel API built for platforms that want to grow.
Omni is Engine's travel booking API that gives any platform built-in hotel booking. Access 500k+ properties, competitive hotel rates, and 24/7 traveler support through a single integration.
WHAT IS OMNI?
A hotel booking API and travel integration for any platform.
Omni is Engine's partner-facing travel booking API. It is a fully managed hotel infrastructure that any platform can embed, regardless of depth of travel experience.
Your users are already booking hotels somewhere. Omni surfaces that booking inside your product so you capture the revenue.
-
Who is Omni for?
Whether you run a field service tool, workforce management platform, staffing application, construction management tool, or vertical SaaS product, Omni lets you add a white label booking API to your platform.
-
How does it work?
You bring the surface. We bring the inventory, rates, payments infrastructure, and 24/7 traveler support. Partners go live in 45 days or less with no need to hire a travel team or manage supplier relationships.
Omni offers two integration paths. Omni Swift is a low-code, co-branded redirect, hosted by Engine. Your team builds a surface; we host the booking experience. Most Swift partners go live within a week.
Omni Halo is a full API integration. You own the entire booking flow end to end, with full access to Engine's REST and gRPC endpoints. Typical Halo timelines are 45 days depending on build scope.
CAPABILITIES
What does Omni cover?
Everything you need to power hotel booking inside your product — from search to settlement.
-
Finding and displaying properties
Search 500k+ properties by coordinates, address, or plain text description. The content layer returns hotel details, images, amenities, and descriptions ready to display in your product. Highly performant with generous rate limits, supporting fast, responsive search for your users.
-
Shopping and rate availability
Surface real-time hotel availability and pricing for your users' specific stay including dates, number of rooms, number of guests. Return the best available offer for each property, including room type, bedding, amenities, and price. Engine handles multi-source inventory and room mapping so your users always see accurate, deduplicated results.
-
Booking and transactions
Engine handles payment processing, fraud detection, and booking confirmation. Partners can support additional guests, attach booking metadata, and integrate Direct Bill for consolidated invoicing.
-
Cancellations and modifications
Preview the refund amount and cancellation conditions before submitting. Engine processes the cancellation and refund automatically to the original payment method. Your users stay informed throughout without any manual intervention from your team.

-
Integration options and deep linking
The Omni travel booking API is available via REST and gRPC. Pre-compiled SDK bindings are available for JVM (Java/Kotlin) with additional language support available on request. All endpoints are secured via Mutual TLS (mTLS) authentication. For Omni Swift integrations, deep linking sends users directly to a specific property's room selection page with dates and guest count pre-filled. Full API documentation, Swagger definitions, and Protobuf files are available for download.
WHY OMNI?
Everything you need to offer travel. Without becoming a travel company.
-
Competitive rates your users will notice
Engine has spent a decade building direct hotel relationships and negotiated rates that are not available on public OTAs. Your users get better rates than they would find on their own. That makes Omni a benefit they use, not just a feature you shipped.
-
No travel team required
Payments, cancellations, modifications, disputes, and 24/7 traveler support are all handled by Engine. You get the revenue and the user experience without the operational complexity of running a travel product.
-
Go live in 45 days or less
Most partners using the Omni Swift path go live within a week, within 45 days using Omni Halo. No lengthy procurement process and no cost to get started.
-
Revenue on every booking
Every booking made through your Omni travel API integration generates revenue share back to your platform. A new revenue stream built on top of behavior your users were already doing.
-
Access to 500k+ properties worldwide
Omni gives your users access to the same multi-source inventory that powers Engine's core travel platform. Over 500,000 properties at every price point, from budget to luxury.
WHO USES OMNI?
Which platforms use the Omni travel API?
Omni is built for platforms where travel already happens. Common use cases include:
-
Existing travel providers
If travel is already part of what you offer, Omni gives you access to Engine's supply network to offer broader property coverage and more competitive rates. More inventory, better pricing, none of the supplier relationship overhead.
-
Event & Ticketing Platforms
75 million people traveled overnight to attend a live event last year. Every one of those bookings is happening outside your platform. Omni's travel booking API integration lets you capture that revenue in days with no operational overhead.
-
Construction & Field Service
56% of field workers spend more than three months a year on the road. Our hotel API for construction platforms and field service software gives your crews access to competitive rates without leaving your platform.
-
Logistics & Fleet Management
Long-haul drivers need hotels on every route. Omni's driver lodging integration and fleet management hotel API bring accommodations into your platform. No separate tool. No personal cards. Just hotels, built in.
-
Healthcare Staffing
Travel nurses and clinicians need accommodations on every assignment. Our healthcare staffing hotel API and travel nurse accommodation integration turn a fragmented lodging expense into a seamless, revenue-generating part of your placement flow.
-
Professional Services & Consulting
Consultants and project teams travel constantly for client engagements. Embed hotel booking into your project management or time-tracking platform and give your users access to Engine-negotiated rates without leaving your workflow.
-
Sports & Tournaments
Tournament families are already booking hotels near every venue. Omni puts hotel booking inside your registration flow. Better rates for families, revenue for your platform, and no operational overhead.
-
HR & Employee Perks
Travel is one of the most requested employee benefits and one of the least served. Our white label booking API and employee hotel integration gives your users access to rates they cannot find anywhere else, turning a passive perks catalog into something employees actually use.

FAQ
Frequently asked questions
Common questions about the Omni hotel API and travel booking integration.
What is a hotel booking API and how does Omni work?
A travel booking API is a technical interface that lets one platform access the inventory, pricing, and booking capabilities of another. Omni is Engine's hotel API. It gives your platform access to Engine's 500k+ property inventory, competitive rates, and booking infrastructure. Your users search, select, and book hotels inside your product. Engine handles the backend complexity.
How is Omni different from an affiliate link or OTA redirect?
Affiliate links and OTA redirects send your users away from your platform to complete their booking on other sites. Omni keeps the booking experience inside your platform, branded with your logo and integrated into your user flow. You keep the user. You capture the revenue.
Do I need travel industry experience to integrate Omni?
No. Omni is built for platforms that do not have travel experience. The Swift path requires almost no travel knowledge. Engine handles inventory, payments, cancellations, and customer support entirely. The Halo path requires more technical depth but comes with full support from Engine's engineering team throughout.
How long does it take to integrate the Omni API?
The Omni Swift path goes live within a week with minimal lift. The Omni Halo full API integration goes live in 45 days or less, depending on the depth of the build and your team's bandwidth. We scope this clearly in the discovery call so you know what to expect before committing.
What kind of technical support does Engine provide?
Engine's product partnerships and engineering team provides hands-on support throughout. This includes API documentation, REST endpoint specs, sandbox environments, and direct access to technical resources. After launch, Engine handles all traveler-facing support so your team does not need to staff a travel desk.
Is there a minimum booking volume or upfront cost to get started with Omni?
There's no minimum to connect and no upfront cost. Access is prioritized for partners that can demonstrate $1M+ in potential annual lodging volume, though we evaluate all partnership inquiries.
How does the Omni hotel booking API handle cancellations?
Partners can preview the refund amount and cancellation conditions before submitting. Engine processes the cancellation and refund automatically to the original payment method. Your users are kept informed throughout without any manual intervention from your team.
What hotel inventory does the Omni API provide access to?
Omni gives your platform access to 500k+ properties worldwide at every price point. The same multi-source inventory that powers Engine's core travel platform, built over a decade of direct hotel relationships and negotiated rates.
