Banque de Luxembourg (Belgium) Open Banking API Access

Reaching your Banque de Luxembourg (Belgium) account data no longer means wrestling with eIDAS certificates or a bespoke bank integration. open-banking.io gives you regulated PSD2 access to Banque de Luxembourg's Belgian branch (BIC BLUXBE41) alongside 2,600+ other EU and UK banks, and it does so under a zero-knowledge design: your balances and transactions are decrypted on your own device with a key that never leaves it. Both business and personal accounts are supported, and a single consent stays valid for up to 180 days before Banque de Luxembourg asks you to renew it.

How to connect Banque de Luxembourg

Connecting happens entirely inside the open-banking.io dashboard — there is no API call, code, or key involved in this step.

  1. Sign up for open-banking.io and set your encryption passphrase. Your key pair is generated locally on your device; open-banking.io only ever holds your public key.
  2. In the dashboard, search for Banque de Luxembourg (Belgium) and choose the account type you hold — business or personal.
  3. You are redirected to Banque de Luxembourg's own secure login, where you authenticate and approve access on the bank's PSD2 consent screen.
  4. Once approved, your accounts sync straight back into your open-banking.io dashboard, ready to view.

Because every credential is entered on the bank's side, open-banking.io never sees your Banque de Luxembourg login.

Access your data

Want the data programmatically? This is an optional step you take after connecting. Open the Developers page, create an API key, and export a credentials.json — it bundles that API key with your private decryption key. From there the CLI reads your existing connection:

openbanking accounts
openbanking transactions
openbanking sync

An SDK and REST API are available too. Every request carries your key in the X-Api-Key header, and each response is decrypted locally with your private key — the API key alone only ever returns ciphertext. The CLI and SDK read and sync connections; they never create them.

All of this runs for roughly EUR 3/month, certificate-free.

Does open-banking.io see my Banque de Luxembourg data?

No. It is zero-knowledge: the servers store only your public key and encrypted blobs. Decryption happens on your device.

Which Banque de Luxembourg accounts can I connect?

How often do I re-authorise?
