What Viator (BYOK) is for

Viator (BYOK) lets an AI assistant read your own Viator data through the Viator API with a key you supply (Viator Partner API key). Read-only: 10 tools (list_destinations, search_destinations, search_products, get_product, list_product_tags, search_attractions, get_attraction, get_availability_schedule, check_availability, list_product_reviews). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.viator.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Viator. Viator and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "What is the Viator destination id for Lisbon?"
• "Find Viator destinations matching 'Kyoto'"
• "What are the best-rated tours in Lisbon under 100 euro?"
• "Show details of Viator product 5010SYDNEY"
• "What product tags does Viator use?"
• "What attractions does Viator list for destination 98?"

What it does

• list_destinations: List all Viator destinations (countries, regions, cities) with id, name, type, parent, time zone, currency, airport codes and coordinates. Use the id in product searches.
• search_destinations: Search Viator destinations by a free-text name and get id, name, parent destination and URL.
• search_products: Search bookable tours and activities in a destination with title, rating, review count, duration and from-price. Free to call; nothing is booked.
• get_product: Get one Viator product: status, title, ticket type, age bands and pricing basis, images and logistics. Description fields depend on the product type.
• list_product_tags: List the Viator product category tags (ids and parent ids) used to filter and describe products.
• search_attractions: List attractions of a destination with name, product count, review summary and URL.
• get_attraction: Get one attraction: name, address, coordinates, opening hours, linked product codes and review summary.
• get_availability_schedule: Get a product's seasonal availability and pricing schedule per option, with from-price and currency.
• check_availability: Check live availability and price of a product on one date for a group (full-access affiliate keys only). Free; it does not hold or book.
• list_product_reviews: List traveler reviews of a product with rating, title, text, date and provider (full-access affiliate keys only).

BYOK key

You bring your own Viator Viator Partner API key (https://partnerresources.viator.com/travel-commerce/affiliate/). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.viator.com over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

What it is not

Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Viator. Viator and its logos are trademarks of their owners and are used only to say which service the connector works with. It is read-only: it never creates, changes, sends or deletes anything in your Viator account.

Viator (BYOK) — Privacy Policy

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Viator (BYOK) is. Viator (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Viator data: Search Viator tours and activities, destinations, attractions, product details, availability and reviews with your own Partner API key. You bring your own Viator Viator Partner API key; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Viator call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to api.viator.com, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Viator rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What Viator receives. The request we make on your behalf, including the key and the arguments, under Viator's own terms and privacy policy. Viator acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Viator gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your Viator data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. Viator (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at Viator at any time to end all access.

Children. Viator (BYOK) is a general-audience service operated by the adult using the assistant, under Viator's own age rules.

Changes. We will post changes here with a new effective date.
