What Hyperline (BYOK) is for

Hyperline (BYOK) lets an AI assistant read your own Hyperline data through the Hyperline API with a key you supply (Hyperline API key (production)). Read-only: 10 tools (get_analytics, list_customers, get_customer, list_subscriptions, list_invoices, list_products, list_transactions, list_ledger_accounts, list_tax_rates, list_quotes). 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.hyperline.co. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Hyperline. Hyperline 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 are our ARR, MRR and 30-day churn in Hyperline?"
  • "Which active customers do we have in Hyperline?"
  • "Show Hyperline customer cus_1."
  • "Which Hyperline subscriptions are active and what ARR do they carry?"
  • "Which Hyperline invoices are late or outstanding?"
  • "What products are in our Hyperline catalog?"

What it does

  • get_analytics: Headline billing numbers: ARR, MRR, active and pending ARR, revenue and churn over the last 30 days. Can be limited to one invoicing entity.
  • list_customers: List customers with name, type, status, currency, country, billing email, external id and payment terms. Cursor-paged.
  • get_customer: Get one customer by id: contact, currency, country, status and payment terms.
  • list_subscriptions: List subscriptions with status, currency, customer, plan, contract dates, estimated ARR, contract value and next payment. Paged with take and skip.
  • list_invoices: List invoices with number, type, status, amounts (total, due, paid, tax), currency, dates and a public link. Cursor-paged, newest first by default.
  • list_products: List catalog products with name, type, status and description.
  • list_transactions: List payment transactions with type, amount, currency, customer, status, payment method type and process and settlement dates.
  • list_ledger_accounts: List general-ledger accounts: code, name, type, currency and current balance. Filter by ledger or type.
  • list_tax_rates: List configured tax rates with code, name, type, country and rate.
  • list_quotes: List quotes with number, status, customer, amount, type and expiry.

BYOK key

You bring your own Hyperline Hyperline API key (production) (https://docs.hyperline.co/api-reference). 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.hyperline.co 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

Live from the Hyperline API (api.hyperline.co) with a BYOK key; documentation: https://docs.hyperline.co/api-reference. 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 Hyperline.
