Kreissparkasse Soltau API Access & Open Banking

Reaching your Kreissparkasse Soltau accounts through a single, private interface no longer means wrestling with bank APIs or eIDAS certificates. open-banking.io links to Kreissparkasse Soltau under PSD2 and pulls your balances and transactions into one dashboard, where every figure is decrypted locally with a key that never leaves your device. Both business and personal accounts (BIC NOLADE21SOL) are covered, and a single consent stays valid for up to 180 days before Kreissparkasse Soltau asks you to re-approve.

Because the platform is zero-knowledge, its servers only ever hold your public key. Nobody at open-banking.io — and no third party — can read what your account contains. All of this runs for roughly EUR 3/month, with no bank certificate to buy or renew.

How to connect Kreissparkasse Soltau

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 open-banking.io and set your encryption passphrase. Your key pair is generated right there on your own device.
  2. In the dashboard, choose Kreissparkasse Soltau and select the account type you need — business or personal.
  3. You are redirected to Kreissparkasse Soltau's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Once approved, your accounts sync back into your dashboard automatically and refresh on their own.

Your credentials are only ever entered on Kreissparkasse Soltau's site — open-banking.io never sees them.

Access your data

Developers who want programmatic access can add it after the connection exists. 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. Requests carry the X-Api-Key header, and each response is decrypted locally with your own key. The CLI and SDK only read and sync connections you already made in the dashboard — they can't create one, and an API key alone returns nothing but ciphertext.

Is a bank certificate required?

No. open-banking.io is certificate-free — you never generate or upload an eIDAS certificate to reach Kreissparkasse Soltau.

How long does access last?

Each Kreissparkasse Soltau consent lasts up to 180 days. When it lapses, simply re-approve from the dashboard to keep syncing.

Can open-banking.io read my transactions?

No. It stores only your public key, so data is decrypted solely on your device — a genuinely zero-knowledge design.
