Viator Supplier API Developer Tools

Welcome to the Viator Supplier API Tools site. This site will help you develop an API endpoint so Viator can request your tour inventory availability real time and insert bookings automatically into your reservation system.

Note: Our Supplier API (and this test site) is intended for the use by Current Viator Suppliers and their system providers. You must be a current Viator Supplier before any development commences. For more information on joining Viator, please visit our New Supplier Page.

This toolkit includes sample product mapping spreadsheets, API documentation, test plans and a test harness for calling your API endpoints with valid requests. The test harness is designed to call your reservation systems' API endpoints with your product inventory specific requests in order to facilitate your development and testing.

To get started, please review the Overview Page, the Documentation Page with API Specifications, Tour Code Mapping Examples and a test plan, our Implementation Approach and the Test Harness Instructions.

We've provided a list of Frequently Asked Questions and when you need help or want to schedule integration testing, please Contact us here.

It's our goal to achieve real-time systems connectivity with as many suppliers as possible so please feel free to reach out for assistance. We look forward to working with our suppliers and their system providers to provide the best experience possible for our shared travellers.

Thanks for your support,

The Viator Supplier API team.
