Sparkasse Lüneburg API Access & Open Banking Data

Reaching your Sparkasse Lüneburg account data no longer means wrestling with bank-specific PSD2 certificates or standing up your own TPP infrastructure. open-banking.io gives you a single, certificate-free path to Sparkasse Lüneburg (BIC NOLADE21LBG) — covering both business and personal accounts — as one of 2,600+ EU and UK banks reachable through the same dashboard. Everything you retrieve is decrypted locally with a key that never leaves your device, so the service itself stays zero-knowledge.

How to connect Sparkasse Lüneburg

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 an open-banking.io account.
  2. Set your encryption passphrase. Your key pair is generated right there on your own device, and only you ever hold the private key.
  3. In the dashboard, search for Sparkasse Lüneburg and choose the account type you need — business or personal.
  4. You're redirected to Sparkasse Lüneburg's own secure login, where you approve access under PSD2 consent (valid for up to 180 days before you renew).
  5. Your accounts sync back into the dashboard, ready to view.

Because approval takes place on the bank's own screen, your credentials are never seen by open-banking.io.

Access your data

Once Sparkasse Lüneburg is connected, developers can optionally read the data programmatically. Open 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 you can 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. The CLI and SDK only read and sync connections that already exist — they never create them. An API key on its own returns ciphertext; without your private key, it stays unreadable.

FAQ

Does open-banking.io store my Sparkasse Lüneburg credentials?

No. You authenticate on Sparkasse Lüneburg's own consent screen, and the platform only ever holds your public key — it cannot decrypt your data.
