Kreissparkasse Nordhausen API & Open Banking Access

Reaching your Kreissparkasse Nordhausen accounts programmatically usually means chasing PSD2 certificates and bank onboarding. open-banking.io removes that friction: it links to the Thuringian savings bank (BIC HELADEF1NOR) through the regulated open-banking network, and every figure that lands in your dashboard is decrypted on your own device with a key only you hold. Both business and personal accounts are supported, and a single approval keeps data flowing for up to 180 days.

The service is certificate-free and zero-knowledge — no eIDAS certificate to buy, and open-banking.io servers store only your public key, so they can never read your statements.

How to connect Kreissparkasse Nordhausen

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

  1. Sign up for open-banking.io and set your encryption passphrase. Your keys are generated locally on your device.
  2. In the dashboard, search for Kreissparkasse Nordhausen and choose the account type you need (business or personal).
  3. You are redirected to Kreissparkasse Nordhausen's own secure login, where you approve access on the bank's consent screen (valid up to 180 days).
  4. Your accounts sync back into the dashboard, ready to view or export.

Access your data

Once the connection exists, developers can optionally read it programmatically. On the Developers page, create an API key and export a credentials.json — this bundles the API key with your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Every request sends the X-Api-Key header, and each response is decrypted locally with your own key. The API key alone only returns ciphertext; without your private key the data stays unreadable — even to open-banking.io. Note there is no connect command: the CLI and SDK only read or refresh connections you already approved in the dashboard.

All of this runs for roughly EUR 3/month.

Do I need a PSD2 certificate for Kreissparkasse Nordhausen?
