5 Leading Travel APIs in 2026 for Ancillary Revenue

Travel APIs interfaces let companies embed tours, attractions and other “things to do” directly into their websites and apps so travellers can bundle experiences with their core bookings. Airlines and hotels already make a significant portion of their income from extras, with the International Air Transport Association (IATA) noting that ancillary and other revenues (everything from seat fees to add‑on experiences) are projected to rise to US$145 billion in revenue for airlines in 2026, and ancillary services now account for roughly 14 % of their total revenue.

By tapping into modern travel APIs, online travel agencies, fintech platforms and even banks can offer curated activities without having to negotiate hundreds of supplier contracts or build complex booking systems themselves.

Tours and Activities APIs

The “experiences” segment is both enormous and under‑exploited. A recent McKinsey and Skift analysis estimated that visitors domestic and international spend about US$1.1–1.3 trillion on experiences such as guided tours, concerts and other paid activities. That spending represents roughly one‑third of the total travel experiences market and it’s growing rapidly.

Unlike flights or hotel rooms, experiences are highly personal and less commoditized, which means margins can be healthier and loyalty stronger. By focusing on this niche, traveltech builders, banks, and loyalty programs can differentiate their offerings and tap into a lucrative revenue stream that travellers are already eager to buy.

Experiences can be one of the most scalable ways to grow ancillary revenue for travel.

Building an experience layer in house sounds simple until you’re staring at supplier contracts, content normalization, real-time availability changes, cancellations, vouchers, customer servicing workflows, and ongoing technical maintenance. That’s why tours and activities APIs and increasingly branded white‑label marketplaces have become a practical layer of modern traveltech: they let you add bookable experiences without turning your roadmap into an integration treadmill.

This deep dive below breaks down the ecosystem in plain language, then compares five well known options so banks, loyalty programs, credit cards, and traveltech companies can weigh the trade offs confidently and choose the right model for their ancillary revenue strategy.

The tours and activities ecosystem in plain English

A helpful way to avoid apples to oranges comparisons is to separate the ecosystem into the roles buyers typically care about. You don’t need jargon to do this, just one basic question: who is the platform built to serve?

1) Operator systems

These are supplier side tools built to help tour operators run day to day operations (inventory, calendars, staff, point of sale). They’re important but they’re not what most enterprise buyers mean when they say “I need tours and activities APIs for my platform.”

2) Consumer marketplaces with partner access

These are B2C marketplaces that sell directly to travelers, with partner programs (API or affiliate tooling) that let other brands distribute that marketplace’s inventory. This can be a fast path to launch, but you’re usually choosing a marketplace led model.

3) Distribution enablement

These are platforms built for partners, travel brands, OTAs, banks, loyalty programs, and super apps, so they can embed and monetize experiences inside their own journeys. Some focus on distributing their own or contracted supply; others also emphasize aggregation and normalization across multiple sources.

How do banks, credit cards, loyalty programs, and travel sellers actually earn revenue from experiences?

This is the part that often gets described vaguely (“engagement,” “retention”), but the commercial mechanics are usually straightforward.

If you’re a travel seller (OTA, marketplace, travel app, mobility platform)

Most travel sellers monetize experiences via:

• Commission / affiliate income per booking (often simplest operationally)
• Merchant margin on eligible inventory (more upside, more responsibility)
• Attach-rate growth: adding “one more thing” to the trip increases basket size and improves unit economics

Experiences also strengthen the customer relationship after the initial flight/hotel purchase, which can lift repeat visits and overall brand stickiness.

If you’re a bank or credit card issuer

For banks and card issuers, the revenue logic is usually less about maximizing margin on a single booking and more about:

• increasing card usage (more transactions, more spend moments)
• improving retention; especially in premium segments
• differentiating beyond generic rewards catalogs

Experiences can fit neatly into cardholder travel portals, premium perks, and points/cashback mechanics, while the “heavy lifting” remains handled by the distribution partner.

If you’re a loyalty program

Experiences work well in loyalty because they can be:

• redeemed (points)
• purchased (cash)
• or combined (points + cash)

This flexibility is important for adoption: it meets members where they are without forcing every interaction into a pure redemption flow.

How can I offer tours and activities without hiring a big operations team?

Most teams don’t fail because experiences aren’t valuable. They fail because the operational surface area grows faster than expected.

A realistic, sustainable setup usually looks like a division of responsibilities:

• The provider handles supplier connectivity, content structure, availability/pricing logic, booking flows, and voucher mechanics.
• Your team focuses on distribution: where experiences appear in your journey, which collections convert, how loyalty mechanics are presented, and how lifecycle marketing drives attach.

This is also where the integration approach matters.

No-code vs low-code vs API-first: what “saving time and resources” actually means

In tours and activities, “time-to-market” isn’t just speed of launch. It’s also how quickly you can get to a stable program without constant engineering churn.

Low-code / no-code (white-label marketplaces)

A branded white-label marketplace is often the fastest route when:

• engineering bandwidth is limited
• you want a branded storefront quickly
• you want to learn what converts before building a bespoke UX

It’s a practical path for banks and loyalty programs because it reduces the number of components you need to build and maintain (search, product detail pages, checkout flows, confirmations, voucher delivery, etc.).

API first (custom build)

API first makes sense when:

• your UX is your differentiator
• you need deeper control over discovery, personalization, and packaging
• you want experiences tightly integrated into your app’s native flow

Many mature programs combine both: start with a low-code storefront to validate demand and refine merchandising, then move deeper into API-led embedding once the experience layer proves its value.

Best travel API to integrate tours and experiences into my platform: what to evaluate first

Before comparing providers, align internally on the few decision points that matter most:

• Inventory fit: Do you need broad, global coverage or specific categories (e.g., attractions ticketing)?
• Go live path: Do you want API first control, white-label speed, or a hybrid approach?
• Commercial fit: Affiliate vs merchant vs mixed models
• Operational expectations: Who owns cancellations, customer issues, voucher delivery, and support handoffs?
• Scalability: Localization, multi-currency, and readiness for large user bases (especially relevant for banks and loyalty platforms).

The best tours and activities APIs to evaluate in 2026

1) Bridgify

What it is
Bridgify is positioned as a global B2B2C experiences infrastructure provider, combining supply aggregation, distribution rails, and AI powered personalization across API, white-label marketplace, and AI agent formats so other brands can embed and monetize experiences inside their own customer journeys.

Why teams choose it
Bridgify emphasizes breadth and flexibility: an aggregated supply of 1M+ access to 1M+ curated tours, activities, events, and lifestyle experiences, spanning affiliate and merchant models. It’s described as an “aggregator of aggregators”. It’s also explicitly positioned for travel brands and traveltech platforms, as well as banks, credit cards, loyalty programs, fintechs, and super apps that want embedded content at enterprise scale.

How it goes live
Bridgify supports a unified API and also offers a full white‑label marketplace option (frontend + backend), which is positioned as a faster path for enterprises that want a branded marketplace without building end-to-end booking flows from scratch.

What to watch for
This solution is positioned as infrastructure for distribution, not an operator tool and not a consumer OTA. The best due diligence question is whether you specifically need a distribution enablement layer with multi‑source aggregation (including broader content types like tours/attractions as well as other ticketed experiences).

2) Holibob

What it is
Holibob provides a GraphQL API that allows authorized partners to query products, check associated availability, and make bookings on behalf of consumers.

Why teams choose it
Holibob often comes up when teams want developer friendly integration (GraphQL), partner focused booking flows, and a platform built around enabling partner distribution rather than requiring partners to build supplier connectivity from scratch.

How it goes live
Holibob’s documentation emphasizes production readiness and a structured pathway to live bookings. For example, it notes that testing is done against the production system and that credentials can be upgraded for live bookings after initial integration milestones. It also offers a payment flow approach where Stripe test credentials can be surfaced in sandbox mode to simulate full payments without real charges.

What to watch for
As with any partner distribution API, clarify early:

• coverage in your priority destinations/categories
• how post-booking servicing is handled
• what flexibility you have in UX, merchandising, and loyalty mechanics

3) GetYourGuide Partner Solutions

What it is
GetYourGuide’s Partner API provides access to GetYourGuide’s marketplace for tours and activities.

Why teams choose it
This option is typically shortlisted by brands that want fast access to a recognizable marketplace catalog and partner tooling designed to reduce manual work. GetYourGuide’s documentation highlights that connecting inventory to your system can enable automatic updates of availability and pricing, automatic booking processing, and voucher/redemption flows where partner barcodes or QR codes can be added to vouchers.

How it goes live
GetYourGuide provides partner-facing documentation and API reference materials for integration.

What to watch for
Because this is marketplace access, it’s best evaluated as: does this marketplace catalog and partner model fit your long term distribution goals? If you anticipate needing multi-source breadth or deeper infrastructure control, validate how far the partner model can stretch before you need additional providers.

4) Musement (TUI Group)

What it is
Musement’s partner documentation is explicit that partners can integrate with its API to sell activities from the Musement catalog. It also offers other partner routes, including a white-label solution, referral links, and widgets.

Why teams choose it
Musement can be attractive when you want multiple ways to start:

• test distribution via widgets/referral links
• launch a branded storefront via white label
• or implement deeper embedding via API

That flexibility can be valuable for organizations that want to validate demand before committing to a full build.

How it goes live
Musement’s documentation is structured around partner needs and is designed to support different levels of integration; from “simple catalog browser” implementations to fuller booking applications.

What to watch for
When a platform offers many go‑to‑market modes, it’s worth clarifying internally which mode you’re actually choosing, and what that implies for UX control, data visibility, and operational responsibility.

5) Tiqets

What it is
Tiqets is best known for attraction and museum ticketing and provides a Distributor API for partners.There primary focus is for the European market.

Why teams choose it
Tiqets tends to be a strong shortlist candidate when your experiences strategy is attraction led and you want a well defined integration surface. Their developer documentation highlights a booking flow guide (create, confirm, cancel) as well as webhooks/notifications for booking changes, cancellations, and customer issues.

How it goes live
Tiqets positions its API program around connecting your checkout to Tiqets inventory for order creation/cancellation and supporting real-time integration.

What to watch for
If your roadmap includes broader tours beyond ticketing, validate whether Tiqets alone covers your product breadth, or whether you’ll need complementary supply for categories outside attractions and museums.

Comparison chart: core differences at a glance

Solutions to add global attractions and activities to my app quickly

If speed is the priority, most teams get there by reducing two forms of complexity:

1. Supplier complexity (avoiding dozens of separate supplier contracts and data schemas).
2. Build complexity (choosing a go-live approach that matches your bandwidth; often white-label first).

A practical deep‑dive approach many enterprise teams use:

• Launch with a low-code/white-label storefront where appropriate.
• Identify what converts and what customers search for.
• Invest in deeper API embedding once you have evidence and internal buy‑in.

Travel and activity aggregators for integrating multiple providers in one platform

If you’re operating across multiple regions, a common question becomes: Do we rely on a single catalog, or do we need a broader aggregation model to hit coverage requirements?

The answer usually depends on your audience:

• A focused leisure audience may be covered well by one strong marketplace catalog.
• A large bank or loyalty ecosystem with diverse members may require broader coverage to avoid “empty search results,” which can hurt adoption and repeat usage.

Best way to offer personalized experiences to my customers through an API

Personalization doesn’t have to start with a complex recommendation engine. Many successful programs begin with practical building blocks:

• Destination collections (“Top experiences in Rome”)
• Segment-based collections (“Family-friendly,” “Rainy day,” “Evening activities”)
• Lifecycle timing (pre-trip vs in-destination)

If you want personalization embedded in the infrastructure itself, that becomes a vendor evaluation point; especially for programs where experiences are tied to loyalty incentives and ongoing engagement.

How to launch a whitelabel marketplace for tours and events

A white-label marketplace is often best treated like a strategic MVP:

• It reduces engineering scope.
• Lets you validate demand quickly.
• Gives you data on what members or travelers actually book.

For banks and loyalty programs, it can be the most practical route to prove value without long internal build cycles; then expand into deeper integration later if adoption justifies it.

Key takeaways

• Ancillary revenue for travel is increasingly driven by attach products and partner monetization. IATA’s outlook for 2026 (with $145B in ancillary and other revenues and currently ancillaries near 14% of revenue ) underlines how structural “add-ons” have become.
• Tours and activities APIs are one of the most practical ways to build that ancillary layer without building a supplier operations organization from scratch.
• The biggest differences between providers usually come down to inventory model, go-live approach (API vs white label vs hybrid), and how much control you want over the customer journey.
• If speed and resource constraints are real (they usually are), low‑code/white‑label options can reduce technical debt and keep teams focused on what actually matters for the business: conversion, merchandising, loyalty mechanics, and distribution.
• The opportunity is large: McKinsey’s estimate of $1.1T–$1.3T in destination visitor experiences spend shows why experiences are becoming a strategic category, not just a “nice add-on.”
