Kreissparkasse Nordhorn API Access & Open Banking

Reaching your Kreissparkasse Nordhorn accounts through open-banking.io means live balances and transactions land in one place — and, if you write code, in your own scripts — without certificates, sandbox paperwork, or a bank developer contract. open-banking.io is a zero-knowledge bridge covering 2,600+ EU and UK banks, including Kreissparkasse Nordhorn (BIC NOLADE21NOH), for both business and personal accounts. Your data is decrypted on your device with a key only you hold, so no one else — not even open-banking.io — can read it.

How to connect Kreissparkasse Nordhorn

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

  1. Sign up at open-banking.io and set an encryption passphrase. Your keys are generated locally on your own device; the service only ever stores your public key.
  2. In the dashboard, pick Kreissparkasse Nordhorn and choose the account type you want to link (business or personal).
  3. You are redirected to Kreissparkasse Nordhorn's own secure login, where you approve access under PSD2 consent — your credentials are entered only on the bank's site.
  4. Your accounts sync back into the dashboard. Consent lasts up to 180 days, after which you simply re-approve on the bank's screen.

Access your data

Once the connection exists, reading it programmatically is an optional developer step. 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. Requests carry your key in the X-Api-Key header, and every response is decrypted locally with your private key. Without that key an API request returns only ciphertext — proof the zero-knowledge model holds even for you.

Pricing is a flat ~EUR 3/month, with no per-call fees or certificate costs.

Do I need a developer account with Kreissparkasse Nordhorn?

No. You approve access on the bank's standard login under PSD2 — no eIDAS certificate or bank developer registration required.

Can open-banking.io see my Kreissparkasse Nordhorn data?

No. It stores only your public key; decryption happens on your device with a private key that never leaves it.

Can the CLI connect the bank for me?

No. The CLI and SDK only read or sync connections that already exist. Connecting is always done in the dashboard against Kreissparkasse Nordhorn's own consent screen.
