Kreissparkasse Verden API Access & Open Banking

Kreissparkasse Verden (BIC BRLADE21VER) serves customers across the Verden district in Lower Saxony, and open-banking.io lets you reach both business and personal accounts through a single, privacy-first workflow. Instead of juggling certificates or eIDAS credentials, you authorise access once and your account balances and transaction history flow into a dashboard where the data is decrypted on your own device with a key nobody else holds.

The service spans 2,600+ EU and UK banks, so once Kreissparkasse Verden is linked you can manage it alongside any other institution you use. Access is certificate-free and costs around EUR 3 per month.

How to connect Kreissparkasse Verden

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 keys are generated locally on your device, so the platform only ever sees your public key.
  3. In the dashboard, pick Kreissparkasse Verden and choose whether you are linking a business or personal account.
  4. You are redirected to Kreissparkasse Verden's own secure login, where you approve access under PSD2 consent.
  5. Your accounts sync back into the dashboard, ready to view.

Consent lasts up to 180 days, after which you simply re-approve on the bank's screen to keep the connection live.

Access your data

Programmatic access is an optional step for developers, taken only after a bank is already connected. From the Developers page you create an API key and export a credentials.json file that bundles the API key with your private decryption key. From there you can 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, because open-banking.io never holds anything that could unlock your data.

Is open-banking.io really zero-knowledge?

Yes. Decryption keys are created and kept on your device. The servers store only your public key and encrypted payloads, so they cannot read your Kreissparkasse Verden data.

Can I connect a business account?

Both business and personal Kreissparkasse Verden accounts are supported. You choose the account type in the dashboard before approving consent.

Do I need certificates or a licence?

No. There are no eIDAS certificates or QWACs to obtain — you authenticate directly on Kreissparkasse Verden's consent screen.
