Connect Belfius to Hypamoon

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

Possible

The check

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

Public API docs
Yes. Public portal with live PSD2 APIs for account information, payment initiation and confirmation of funds. Read the docs
A key you create yourself
No. Sandbox and production are only for third parties authorised under PSD2, who request access. developer.belfius.be
Versions or a changelog
Not confirmed.
How it signs in
Not described on the open pages; access is for authorised PSD2 providers.
Webhooks
Not confirmed.
Hosting
Cloud
Condition
PSD2 APIs need a licence as a third party provider and an eIDAS certificate; a normal company uses an aggregator. Statements can also come in as a CODA file from business banking.

Your own payments overview on your Belfius account, through a licensed aggregator.

  • Balances and transactions, after you give consent at Belfius.
  • AI that matches incoming payments to invoices, with your team approving every match.

Ask your chat

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

  • Which invoices are still unpaid after 30 days?
  • What came in on the account yesterday?

On a schedule

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

  1. Every 15 minutes

    New transactions since the last daily check.

    AI decides

    AI proposes which invoice each incoming payment settles.

    Then

    Your team gets an email with the matches to approve.

A screen for your team or customers

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

  • For your team

    A screen with open invoices and the payments that came in against them.

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

Good to know

  • Belfius only offers its PSD2 APIs; no API for business customers on their own accounts was found.
