What is the Viator API?

The Viator API is a powerful travel technology interface provided by Viator (a TripAdvisor company) that allows businesses to programmatically access tours, activities, excursions, tickets, and sightseeing experiences across 2,000+ destinations globally. The API supports real-time availability, dynamic pricing, instant booking confirmation, secure payment workflows, and rich content (images, descriptions, reviews). Through professional Viator API integration using secure API Key authentication and API credentials, businesses can resell curated activities directly from their own platforms and enhance their travel-booking software capabilities.

Access to the Viator API requires secure API credentials and authentication mechanisms to ensure protected access to inventory, availability schedules, and booking workflows.

Viator Partner API

The Viator Partner API is Viator’s unified integration framework that allows approved partners to distribute tours, activities, and experiences directly through their own platforms. Instead of offering multiple standalone APIs, Viator operates a single Partner API with different access levels, determined by a partner’s business model, technical readiness, and commercial agreement.

Through this API, partners can connect to Viator’s global inventory and integrate real-time availability, pricing, and booking workflows into their websites or applications with implementation guided by Viator’s official API documentation and technical specifications.

Affiliate Access Within the Viator Partner API

Affiliate access, commonly referred to as the Viator Affiliate API, is an access model within the Viator Partner API designed for publishers, content-driven travel platforms, bloggers, and referral-based businesses that want to monetize their audience by promoting tours and activities without managing transactions. Partners using this access level integrate Viator’s product content and availability into their platforms and guide users to complete their bookings through Viator’s system.

Depending on approval, affiliates may receive Basic access, Full access, or Full + Booking access, allowing limited booking interactions to occur on the partner’s platform; however, all payments and final checkout are handled by Viator, which remains the merchant of record.

Customer payment processing, booking confirmation, and post-booking support are managed entirely by Viator, making this access model well-suited for businesses seeking a commission-based revenue stream without the operational responsibility of handling payments, refunds, or customer liabilities.

Merchant Access Within the Viator Partner API

Merchant access is intended for online travel agencies, destination management companies, and enterprise travel platforms that require complete ownership of the booking and payment experience. Partners approved for this access level can fully integrate Viator’s booking capabilities into their systems while managing customer transactions directly on their own platform.

Under the Merchant model, the partner acts as the merchant of record, controlling checkout flows, pricing presentation, payment collection, and customer communication. At the same time, product content, availability, and booking confirmations remain synchronized with Viator’s backend systems to ensure accuracy and consistency.

Merchant access is subject to Viator’s approval, technical evaluation, and commercial terms and is typically granted to organizations with strong operational infrastructure, compliance readiness, and customer support capabilities.
