Belfius API Access — Connect Belgian Accounts

Pulling live financial data out of Belfius no longer requires bank-specific integrations or eIDAS certificates. open-banking.io gives you one API to authenticate a Belfius customer and stream their account information straight into your product, dashboard, or bookkeeping flow.

Belfius (BIC GKCCBEBB) is one of Belgium's largest retail and business banks, and open-banking.io supports both personal and business account holders through the same regulated PSD2 connection.

How to connect Belfius

  1. Register for an open-banking.io API key — no certificate, no onboarding paperwork.
  2. Call the connect endpoint and select Belfius as the target institution.
  3. Redirect your user to Belfius, where they approve access with their own banking credentials.
  4. Receive the access token and begin fetching account data immediately.

What data you can access

Once a Belfius customer consents, you can read:

  • Accounts — IBANs, account names, currency, and product type
  • Balances — current and available amounts, refreshed on demand
  • Transactions — dated entries with counterparties, references, and amounts

A single Belfius authorisation stays valid for up to 180 days before the customer needs to reconfirm. Beyond Belfius, the same integration reaches 2,600+ banks across the EU and UK, so adding the next institution is a configuration change rather than a new project.

Privacy by design

open-banking.io is zero-knowledge: your users' credentials are entered only on Belfius's own pages, and we never store or relay them. The platform is certificate-free, removing the eIDAS/QWAC burden that normally slows PSD2 projects to a crawl. Data flows through you, not around you.

Pricing

Flat and predictable at roughly EUR 3/month — no per-call surprises, no enterprise minimums, and every supported bank included.

FAQ

Do I need an eIDAS certificate to reach Belfius?

No. open-banking.io handles the regulated layer, so you connect to Belfius with an ordinary API key and no certificate at all.

How often can I refresh Belfius balances and transactions?

You can pull fresh data on demand within the active consent window, which lasts up to 180 days per Belfius authorisation.

Can I connect both personal and business Belfius accounts?

Yes. Both account types are supported through the same flow — the customer simply approves the account they hold.
