Kreissparkasse Walsrode Open Banking & API Access

Pulling your Kreissparkasse Walsrode figures into your own tools no longer means chasing bank certificates or building a PSD2 stack. open-banking.io gives you a single, secure path to your accounts at the Heidekreis savings bank (BIC NOLADE21WAL), covering both business and personal banking. Everything is decrypted on your own machine with a key only you hold, so the service reads ciphertext and nothing more.

How to connect Kreissparkasse Walsrode

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

  1. Sign up for open-banking.io and set your encryption passphrase. Your keys are generated locally on your device the moment you do.
  2. In the dashboard, search for Kreissparkasse Walsrode and choose your account type (business or personal).
  3. You are redirected to Kreissparkasse Walsrode's own secure login, where you approve access under PSD2. Your bank grants a consent lasting up to 180 days before you renew it.
  4. Your accounts sync straight back into your dashboard, ready to view.

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

Access your data

Once Kreissparkasse Walsrode is connected, developers can optionally read the data 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 only ever returns ciphertext; without your private key the data stays unreadable — even to open-banking.io, which stores only your public key.

This zero-knowledge, certificate-free design keeps you in control, and it costs roughly EUR 3/month across 2,600+ supported EU and UK banks.
