Kreissparkasse Northeim API Access & Open Banking

Reaching your Kreissparkasse Northeim accounts through open-banking.io means your balances and transactions land in one dashboard you actually control. There is no bank certificate to buy, no eIDAS QWAC to register, and no server that can peek at your statements — open-banking.io is zero-knowledge, so it only ever holds your public key while the readable data is unlocked on your own device. Kreissparkasse Northeim (BIC NOLADE21NOM) is covered for both business and personal accounts, with PSD2 consent lasting up to 180 days before you renew.

How to connect Kreissparkasse Northeim

Connecting happens entirely in 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 an encryption passphrase. Your cryptographic keys are generated locally, on your device, from that passphrase.
  2. In the dashboard, search for Kreissparkasse Northeim and choose the account type you need — business or personal.
  3. You are redirected to Kreissparkasse Northeim's own secure login, where you authenticate and approve access on the bank's PSD2 consent screen.
  4. Once you confirm, your accounts sync back into the dashboard and refresh automatically for the life of the consent (up to 180 days).

That's the whole flow. open-banking.io never sees your Kreissparkasse Northeim credentials — you enter them only on the bank's site.

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 together with your private decryption key. From there 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. The API key alone returns only ciphertext, which is exactly what zero-knowledge means. Note the CLI and SDK only read and sync connections you already approved in the dashboard — there is no connect command.

Does open-banking.io store my banking password?

No. You authenticate directly on Kreissparkasse Northeim's login, and only your public key is held server-side.
