Banque de Luxembourg API Access & Open Banking

Banque de Luxembourg is a long-established private and business bank serving clients across the Grand Duchy. With open-banking.io you can bring its account and transaction data into a single dashboard — and, when you want to, into your own scripts — without handling eIDAS certificates, PSD2 licences, or bank-specific integrations. open-banking.io covers 2,600+ EU and UK institutions, and Banque de Luxembourg (BIC BLUXLULL) is one of them, for both business and personal accounts.

The defining feature is privacy. open-banking.io is zero-knowledge: your encryption keys are generated on your own device and your bank data is decrypted locally. The service stores only your public key, so it can move ciphertext around but can never read your balances or transactions. That model is certificate-free and costs roughly EUR 3/month.

How to connect Banque de Luxembourg

Connecting happens entirely in 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 an encryption passphrase. Your private key is created locally from it and never leaves your device.
  2. In the dashboard, choose Banque de Luxembourg and select the account type you hold — business or personal.
  3. You are redirected to Banque de Luxembourg's own secure login, where you approve access under PSD2. open-banking.io never sees your banking credentials.
  4. Your accounts sync back into the dashboard. The consent you grant lasts up to 180 days, after which you simply re-approve on the bank's screen.

Access your data

Programmatic access is an optional step for developers, available only after a connection exists. On the Developers page, create an API key and export a credentials.json — this bundles the API key together with your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API directly. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. Note that the API key alone only ever returns ciphertext — without your private key there is nothing readable to see. The CLI and SDK read and sync existing connections; they cannot create one.

Is Banque de Luxembourg supported for both business and personal accounts?

Yes. Both account types can be connected and synced under BIC BLUXLULL.

Can open-banking.io read my Banque de Luxembourg data?

No. It is zero-knowledge and holds only your public key. Decryption happens on your device.

How long does access last before I re-approve?

Up to 180 days per consent, after which you re-authorise on Banque de Luxembourg's own login.
