What Envoice (BYOK) is for

Envoice (BYOK) lets an AI assistant read your own Envoice data through the Envoice API with a key you supply (Envoice API key). Read-only: 10 tools (list_countries, list_currencies, list_tax_rates, list_work_types, list_payment_gateways, list_invoice_categories, list_products, list_invoices, get_product_details, list_estimations). 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 www.envoice.in. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Envoice. Envoice 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 countries can I choose in Envoice?"
• "Which currencies does Envoice support?"
• "Which tax rates are set up in my Envoice account?"
• "What work types can I bill in Envoice?"
• "Which payment gateways can my Envoice invoices use?"
• "Which invoice categories do I use in Envoice?"

What it does

• list_countries: List the countries Envoice supports, with id, name and code.
• list_currencies: List the currencies Envoice supports, with id, ISO code, name and symbol.
• list_tax_rates: List the tax rates configured in your account with name and percentage.
• list_work_types: List the work types (billable activity titles) defined in your account.
• list_payment_gateways: List the payment gateways Envoice offers and the currencies each supports (an empty currency list means all).
• list_invoice_categories: List the invoice categories of your account, optionally filtered by a search text.
• list_products: List the products (sellable items with a payment page) of your account with price, shipping, status and currency.
• list_invoices: List invoices with number, status, dates, amounts and currency (client details and notes are left out).
• get_product_details: Get one product by id: name, description, status, price, shipping and currency (access tokens and attachments are left out).
• list_estimations: List estimations (quotes) with number, status, expiry, amounts and currency (client details and notes are left out).

BYOK key

You bring your own Envoice Envoice API key (https://www.envoice.in/account/settings#api-tab). 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 www.envoice.in 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.

Envoice (BYOK) — Privacy Policy

Effective 16 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Envoice (BYOK) is. Envoice (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Envoice data: Read your Envoice products, invoices, estimations, tax rates, categories and supported currencies and countries with your own API key and secret. You bring your own Envoice Envoice API key; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Envoice 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 www.envoice.in, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Envoice 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 Envoice receives. The request we make on your behalf, including the key and the arguments, under Envoice's own terms and privacy policy (https://www.envoice.in/terms). Envoice acts at your direction and is the only recipient of the data of your request besides our hosting provider.

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

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

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