Implementing the Viator Partner API

The Viator Partner API comprises a set of endpoints that can support the operation of a fully-featured tours and experiences booking website or application; or, it can be integrated with your existing travel-booking software.


We are deprecating our V.1 API on December 1, 2023

On December 1, 2023, we are removing access to our V.1 API. Any existing V.1 integrations must move onto our v.2 API. Please see our Upgrade Path for more details.

Getting started

1. Familiarize yourself with your partner type

While we have one Viator Partner API, there are endpoints that are only available to a certain partner type. You can be one of the following partner types:

  • Affiliate (Basic Access)
  • Affiliate (Full Access)
  • Affiliate (Full + Booking Access)
  • Merchant
