What Klaviyo Tags (BYOK) is for

Klaviyo Tags (BYOK) lets an AI assistant read your own Klaviyo Tags data through the Klaviyo Tags API with a key you supply (private API key (starts with pk_)). Read-only: 7 tools (list_tags, get_tag, list_tag_groups, get_tag_group, list_coupons, get_coupon, list_web_feeds). 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 a.klaviyo.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Klaviyo Tags. Klaviyo Tags 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:

• "Which tags do I use in Klaviyo?"
• "What is the name of Klaviyo tag T1?"
• "Which tag groups exist in Klaviyo?"
• "Is the Klaviyo tag group G1 exclusive?"
• "Which coupons are set up in Klaviyo?"
• "How is the Klaviyo coupon SPRING10 configured?"

What it does

• list_tags: List tags used to organize campaigns, flows, lists and segments, at most 50 per page. Needs the tags:read scope.
• get_tag: Get one tag by ID with its name.
• list_tag_groups: List tag groups with name, whether tags in the group are mutually exclusive and whether it is the default group, at most 25 per page.
• get_tag_group: Get one tag group by ID with its name, exclusivity and default flag.
• list_coupons: List coupons with external ID, description and the low-balance monitoring and code reassignment settings, at most 100 per page. Individual coupon codes are not returned. Needs the coupons:read scope.
• get_coupon: Get one coupon by ID with external ID, description and its monitoring and reassignment settings (coupon codes are not returned).
• list_web_feeds: List web feeds (external data sources used in templates) with name, request method, content type, refresh status and dates, at most 20 per page. The feed URL is not returned. Needs the web-feeds:read scope.

BYOK key

You bring your own Klaviyo Tags private API key (starts with pk_) (https://developers.klaviyo.com/en/docs/authenticate_). 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 a.klaviyo.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

• https://developers.klaviyo.com/en/reference/get_tags (the API this connector calls, with a BYOK key)

Live from the Klaviyo Tags API (a.klaviyo.com) with a BYOK key; documentation: https://developers.klaviyo.com/en/reference/get_tags. Endpoints checked against that documentation on 2026-10-16.

What it is not

Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Klaviyo Tags. Klaviyo Tags 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 Klaviyo Tags account.

Klaviyo Tags (BYOK) — Privacy Policy

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

What Klaviyo Tags (BYOK) is. Klaviyo Tags (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Klaviyo Tags data: Read your Klaviyo tags and tag groups, coupons (settings only, not codes) and web feeds (status only) with your own private API key. You bring your own Klaviyo Tags private API key (starts with pk_); the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Klaviyo Tags 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 a.klaviyo.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 Klaviyo Tags 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 Klaviyo Tags receives. The request we make on your behalf, including the key and the arguments, under Klaviyo Tags's own terms and privacy policy. Klaviyo Tags acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Klaviyo Tags 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 Klaviyo Tags 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. Klaviyo Tags (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 Klaviyo Tags at any time to end all access.

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

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