Landesbank Baden-Württemberg API Access & Open Banking

Landesbank Baden-Württemberg (LBBW, BIC SOLADEST600) is one of Germany's largest Landesbanken, and open-banking.io gives you a clean, privacy-first way to reach its account and transaction data. Both business and personal accounts are supported under PSD2, and every consent you grant lasts up to 180 days before a quick renewal. Nothing here needs an eIDAS certificate or a bank-specific integration project — you connect once in a web dashboard and your data stays encrypted end to end.

The defining trait of open-banking.io is that it is zero-knowledge. When you sign up you set an encryption passphrase, and the keys are generated on your own device. The service only ever stores your public key, so its servers can never read or decrypt your LBBW data — decryption happens locally, on your machine, with a private key only you hold.

How to connect Landesbank Baden-Württemberg

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 keys are created locally, on your device).
  2. In the dashboard, choose Landesbank Baden-Württemberg and select the account type you want — business or personal.
  3. You are redirected to LBBW's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Your accounts sync back into the dashboard, ready to view. That consent stays valid for up to 180 days.

Access your data

Reading LBBW data programmatically is an optional developer step after connecting. From the Developers page, create an API key and export a credentials.json — this bundles the API key together with your private decryption key. With it you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. An API key alone only ever returns ciphertext — without your private key there is nothing readable to see. The CLI and SDK only read and sync connections you already made in the dashboard; they cannot create one.

All of this runs for roughly EUR 3/month, across 2,600+ EU and UK banks.

Do I need a certificate to connect LBBW?

No. open-banking.io is certificate-free — no eIDAS or QWAC setup. You approve access directly on LBBW's consent screen.

Can open-banking.io read my LBBW transactions?

No. It is zero-knowledge and holds only your public key. Your data is decrypted locally with a private key that never leaves your device.

Up to 180 days per approval, for both business and personal accounts, after which you re-approve on LBBW's login screen.
