Deutsche Bank Luxembourg Open Banking & API Access

Deutsche Bank Luxembourg (BIC DEUTLULL) serves the Grand Duchy's private, corporate and institutional clients. If you hold a business or personal account there, open-banking.io lets you reach your balances and transactions without paperwork, eIDAS certificates or a bank-side developer programme — and without anyone but you ever being able to read the results.

open-banking.io is a zero-knowledge gateway to 2,600+ EU and UK banks. Your encryption keys are generated on your own device, so the service only ever holds your public key. Every figure that lands in your dashboard is decrypted locally, under a passphrase that never leaves your machine.

How to connect Deutsche Bank

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

  1. Sign up for open-banking.io and set your encryption passphrase; your private key is created locally at this moment.
  2. In the dashboard, search for Deutsche Bank (Luxembourg) and choose the account type you hold — business or personal.
  3. You are redirected to Deutsche Bank's own secure login, where you approve access under PSD2. Your credentials go only to the bank.
  4. Your chosen accounts sync back into the dashboard. Consent 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 you can take after connecting. 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. An API key on its own returns only ciphertext — without your private key, there is nothing readable to see. The CLI and SDK read and refresh existing connections; they never establish one.

Does open-banking.io see my Deutsche Bank data?

No. It is zero-knowledge and holds only your public key. Decryption happens on your device, so plaintext balances and transactions are never visible to the service.

Do I need an eIDAS certificate or a developer account?

No. It is certificate-free. You approve access on Deutsche Bank's own consent screen — no TPP licence or bank onboarding required.

What does it cost?

Around EUR 3/month for access to Deutsche Bank Luxembourg and every other supported institution.
