What Zuper Billing (BYOK) is for

Zuper Billing (BYOK) lets an AI assistant read your own Zuper Billing data through the Zuper Billing API with a key you supply (Zuper API key). Read-only: 5 tools (list_quotes, list_invoices, list_credit_notes, list_service_contracts, list_payment_transactions). 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 *.zuperpro.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Zuper Billing. Zuper Billing 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 Zuper quotes are still in draft?"
• "Which Zuper invoices are awaiting payment?"
• "Which Zuper credit notes are still unapplied?"
• "Which Zuper service contracts expire this quarter?"
• "What payments were recorded in Zuper recently?"

What it does

• list_quotes: List quotes and estimates with number, date, expiry, total, status and expired or converted flags (no customer details).
• list_invoices: List invoices with number, date, due date, total, status and paid flag (no customer details).
• list_credit_notes: List credit notes with number, date, total, used and remaining amount and status.
• list_service_contracts: List service contracts with number, name, start and end dates, term, approval status, total and active or expired flags (no customer details).
• list_payment_transactions: List payment transactions with amount, currency, payment mode, status, source and time (no payer details).

BYOK key

You bring your own Zuper Billing Zuper API key (https://developers.zuper.co/docs/getting-started). 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 *.zuperpro.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.zuper.co/reference/get-all-invoices (the API this connector calls, with a BYOK key)

Live from the Zuper Billing API (*.zuperpro.com) with a BYOK key; documentation: https://developers.zuper.co/reference/get-all-invoices. Endpoints checked against that documentation on 2026-10-16.

What it is not

Zuper Billing 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 Zuper Billing account.

Zuper Billing (BYOK) — Privacy Policy

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

What Zuper Billing (BYOK) is. Zuper Billing (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Zuper Billing data: Read your Zuper quotes, invoices, credit notes, service contracts and payment transactions (amounts, dates and statuses only) with your own API key. You bring your own Zuper Billing Zuper API key; the assistant sends it to us with each request.

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

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

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

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