Prisma Reviews / Integrations / Viator

Prisma Reviews is a reviews API that reads Viator reviews from the business’s public Viator listing, in the same JSON format as its other 83 platforms. It can’t reply to Viator reviews by API: each review carries a url to answer it on Viator. Reviews are read in full once a week, and reviews Viator no longer shows are removed. Included in the free Spark plan (2 locations, no card).

Read only Beta

Reviews of the tour or activity from Viator and Tripadvisor, with stars, title, text, reviewer, language, date and your answer. One API key, the same JSON fields as every other platform (rating, text, author, date, reply, url) and a webhook for each new review.
