Kreissparkasse Ludwigsburg API Access & Open Banking

Reaching your Kreissparkasse Ludwigsburg accounts programmatically usually means wrestling with PSD2 certificates and bank-specific sandboxes. open-banking.io removes that layer entirely. It gives you a single, certificate-free way to view balances and transactions from Kreissparkasse Ludwigsburg (BIC SOLADES1LBG), covering both business and personal accounts, with every byte decrypted on your own device.

Because the platform is zero-knowledge, the encryption keys that unlock your data are generated locally and never leave your control. open-banking.io stores only your public key, so its servers can never read what you sync — a genuinely different posture from most aggregators.

How to connect Kreissparkasse Ludwigsburg

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 your encryption passphrase. Your keys are created right there on your device.
  2. In the dashboard, choose Kreissparkasse Ludwigsburg and select the account type you want to link — business or personal.
  3. You are redirected to Kreissparkasse Ludwigsburg's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Your accounts sync back into the dashboard, ready to view. Consent lasts up to 180 days, after which you simply re-approve.

That's the whole flow. No certificate to register, no developer redirect, and the bank credentials only ever touch Kreissparkasse Ludwigsburg's own pages.

Access your data

Once a connection exists, developers can optionally read it programmatically. On the Developers page, create an API key and export a credentials.json — this bundles your 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 directly. Requests carry the X-Api-Key header, and every response is decrypted locally with your own key. An API key alone only ever returns ciphertext, which is exactly what zero-knowledge means. The CLI and SDK read and sync existing connections; they never connect a bank themselves.

All of this runs for roughly EUR 3/month, across 2,600+ supported EU and UK banks.

Do I need an eIDAS certificate for Kreissparkasse Ludwigsburg?

No. open-banking.io is certificate-free — you authenticate on the bank's consent screen and skip PSD2 certificate management entirely.

How long does access to Kreissparkasse Ludwigsburg last?
