Connect SmartBill to Hypamoon

Possible, with help from SmartBill. The API is documented, but you cannot just create a key: access goes through SmartBill first.

The check

Three questions about the API of SmartBill, answered from its own docs.

Public API docs
Yes. SmartBill links to its API reference at api.smartbill.ro. Read the docs
A key you create yourself
No. SmartBill asks you to contact its technical support at vreauapi@smartbill.ro to connect, and lists API under additional modules. smartbill.ro
Versions or a changelog
Not confirmed.
How it signs in
Access is arranged with SmartBill support; the login method was not readable in the API reference.
Webhooks
Not confirmed.
Hosting
Cloud
Condition
Ask SmartBill support for API access; API is listed as an additional module.

Your own invoice flow on SmartBill, built around how your customers order.

  • Invoices, proformas and payments, from the SmartBill API.
  • AI that drafts the invoice from an order and flags missing tax details, with you approving before it is issued.
  • A screen for your team and a short weekly email for you.

Ask your chat

Answers straight from your SmartBill data, in Claude or another chat with the full Hypamoon connection.

  • Which proformas from this month have not become an invoice yet?
  • Which orders from today still need an invoice?

On a schedule

SmartBill has no webhooks we could confirm, so an agent checks every 15 minutes and decides what happens next.

  1. Every 15 minutes

    New orders in your web shop that have no invoice yet.

    AI decides

    AI checks the customer, CIF and VAT and prepares the invoice.

    Then

    The invoice is issued in SmartBill after you approve it.

    AI proposes, you approve

A screen for your team or customers

An app on your own address, with sign-in, on top of the same SmartBill data.

  • For your team

    A daily list for your team of invoices waiting for approval.

SmartBill stays the core: your chat builds the rest on its API, as an adapter plus an app and agents in your Hypamoon project. Reading starts after you click Allow in the portal. Every change an agent or a chat makes in SmartBill waits for your approval, one call at a time. How adapters work

Good to know

  • SmartBill offers both a free e-commerce plugin and API integration. Ask support which plan includes API access.
