Sparkasse Uelzen Lüchow-Dannenberg Open Banking API

Sparkasse Uelzen Lüchow-Dannenberg (BIC NOLADE21UEL) serves the Lüneburg Heath and Wendland region of Lower Saxony. With open-banking.io you can pull your account balances and transaction history into one place — and, if you write software, read that same data programmatically. There is no certificate to buy and no bank-side developer contract to sign: everything runs through a PSD2 consent you approve yourself, and every figure is decrypted on your own device with a key nobody else holds.

open-banking.io reaches 2,600+ banks across the EU and UK. Both business and personal Sparkasse Uelzen Lüchow-Dannenberg accounts are supported, and a single consent stays valid for up to 180 days before the bank asks you to renew it.

How to connect Sparkasse Uelzen Lüchow-Dannenberg

Connecting happens entirely in the open-banking.io dashboard — not through any API call or key:

  1. Sign up at open-banking.io and set your encryption passphrase. Your keys are generated locally on your device, so open-banking.io only ever stores your public key.
  2. In the dashboard, choose Sparkasse Uelzen Lüchow-Dannenberg and pick the account type — business or personal.
  3. You are redirected to Sparkasse Uelzen Lüchow-Dannenberg'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.

No code, no redirect you build, no API key is involved in this step — you authorise directly with the bank.

Access your data

Once the connection exists, developers can optionally read it in code. Open the Developers page, create an API key, and export a credentials.json — it 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. Requests carry the X-Api-Key header, and every response is decrypted locally with your own key. The CLI and SDK only read or sync connections that already exist — they never create one.

Because open-banking.io is zero-knowledge, an API key alone returns only ciphertext; without your private key the data stays unreadable. Access costs around EUR 3/month.

Do I need an eIDAS certificate?

No. open-banking.io is certificate-free — you approve access on the bank's consent screen and never handle QWAC/QSEAL certificates.

Can open-banking.io staff see my Sparkasse Uelzen Lüchow-Dannenberg transactions?

No. The service holds only your public key. Decryption happens on your device, so servers only ever store encrypted data.

Up to 180 days, after which Sparkasse Uelzen Lüchow-Dannenberg asks you to re-approve access from the dashboard.
