What Loyverse (BYOK) is for

Loyverse (BYOK) lets an AI assistant read your own Loyverse data through the Loyverse API with a key you supply (personal access token). Read-only: 12 tools (get_merchant, list_stores, list_items, list_variants, list_categories, list_inventory, list_receipts, get_receipt, list_shifts, list_employees, list_customers, list_payment_types). 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.loyverse.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Loyverse. Loyverse 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 Loyverse business does my token belong to?"
• "What stores does my Loyverse account have?"
• "Which items are in my Loyverse catalog?"
• "Find the Loyverse variant with SKU 10001"
• "What item categories do I have in Loyverse?"
• "How much stock do I have per store in Loyverse?"

What it does

• get_merchant: Show the Loyverse merchant account: business name, country, currency and creation date.
• list_stores: List the stores (locations) of the account with address, phone and creation date.
• list_items: List catalog items with category, tracking flags, image and their variants (SKU, barcode, price, per-store availability). Page with the cursor.
• list_variants: List item variants with SKU, barcode, cost and default price; filter by SKU or item ids.
• list_categories: List item categories with their colour and creation date.
• list_inventory: List stock levels (in_stock) per item variant and store, optionally for chosen stores or variants.
• list_receipts: List sales and refund receipts, newest first when order is DESC, with totals, tax, tip, store, employee and line items. Filter by store and date range.
• get_receipt: Get one receipt by its receipt number with line items, discounts, taxes and payments.
• list_shifts: List cash shifts with opening and closing time, sales, refunds, discounts, cash expected and counted.
• list_employees: List employees with id, name, owner flag and the stores they work in (no contact details are returned).
• list_customers: List customers with visit counts, total spent, points and first and last visit (name only; no email, phone or address is returned).
• list_payment_types: List the payment types configured in the account (cash, card and others) with the stores they apply to.

BYOK key

You bring your own Loyverse personal access token (https://r.loyverse.com/dashboard/#/integrations/tokens). 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.loyverse.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

Loyverse (BYOK) — Privacy Policy

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

What Loyverse (BYOK) is. Loyverse (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Loyverse data: Read your Loyverse point-of-sale stores, items, inventory, receipts, shifts and staff with your own access token. You bring your own Loyverse personal access token; the assistant sends it to us with each request.

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

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

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

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