What you can build

Create invoices and receipts from your own order flow, and look up unpaid invoices of a customer from your chat.

Your chat writes it as a Hypamoon adapter from the docs above. Reading starts after you click Allow in the portal, and every write waits for your approval, one call at a time. How adapters work

Good to know

  • Your adapter uses a fixed key: you paste it once in the Hypamoon portal, never in the chat, and it only goes to the API host you allow.
  • The API can create, change and delete invoices, receipts and their lines. Ask Fakturownia how they announce breaking changes before you rely on an adapter.
