Connect Moloni to Hypamoon

Yes, with one catch. Moloni has an open API that you can use yourself, but it signs in with OAuth only, and that takes more work in a Hypamoon adapter today.

Open

The check

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

Public API docs
Yes. Read the docs
A key you create yourself
Yes. Enable the API yourself under Settings > Developers, set a Developer ID and callback URI, and get a client secret; developers never pay for this. moloni.pt
Versions or a changelog
Yes. Numbered API versions with a dated changelog. moloni.pt
How it signs in
OAuth 2.0 with your developer ID and client secret, using your Moloni login or an authorization code; access tokens last 1 hour and refresh tokens 14 days.
Webhooks
Not confirmed.
Hosting
Cloud

In practice

What it takes in a real Moloni administration.

Getting access
You enable the API in your own Moloni account under Settings > Developers, set a Developer ID and callback URI, and use the client secret you get to request tokens.
Limits
None published.
Writing
Read and write. Insert documents such as invoices with invoices/insert, as a draft or closed.
Cost
Developers never have to pay for API access, according to Moloni. moloni.pt

Your own customer portal on Moloni, with documents and payments in one place.

  • Customers, products, stock and documents such as invoices and receipts, straight from Moloni.
  • AI that drafts invoices from orders and spots customers who pay late, with you approving every change.
  • A portal for your customers and a short weekly email for you.

Ask your chat

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

  • Which customers have open invoices past their due date?
  • Which products sold most this month?

On a schedule

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

  1. Every 15 minutes

    New orders from your own web form that are not invoiced yet.

    AI decides

    AI matches the customer and the products and checks the tax and exemption reason.

    Then

    A draft invoice is created in Moloni.

    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 Moloni data.

  • For your customers

    Customers sign in and see their own invoices and receipts, straight from Moloni.

Add Hypamoon

Text messages, email, phone, payments and agents run in the same project as the adapter.

  • Agent on a schedule

    Once a week, an agent emails you the invoices that passed their due date.

Moloni 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 Moloni waits for your approval, one call at a time. How adapters work

Good to know

  • Moloni signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Moloni takes more work: ask your chat to check this first.
  • Tokens expire, so an adapter has to refresh them; the password flow needs a Moloni login, best a separate user for the integration.
