Kreis- und Stadtsparkasse Wasserburg am Inn API

Reaching your Kreis- und Stadtsparkasse Wasserburg am Inn balances and transactions no longer means scraping statements or wrestling with eBanking exports. open-banking.io gives you PSD2-based access to this Bavarian Sparkasse (BIC BYLADEM1WSB) across both business and personal accounts, and hands the data back to you as clean, structured records you can actually build on.

The whole model is zero-knowledge. When you sign up you set an encryption passphrase, and the key material is generated on your own device. open-banking.io stores only your public key, so its servers can never read or decrypt what flows through them. There are no eIDAS certificates to buy, no bank sponsorship to arrange, and no infrastructure to run — just a straightforward connection you approve yourself.

How to connect Kreis- und Stadtsparkasse Wasserburg am Inn

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

  1. Create your open-banking.io account and set your encryption passphrase (your keys are generated locally, never uploaded).
  2. In the dashboard, search for Kreis- und Stadtsparkasse Wasserburg am Inn and choose your account type — business or personal.
  3. You are redirected to Kreis- und Stadtsparkasse Wasserburg am Inn's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Your accounts sync straight into the dashboard. Consent lasts up to 180 days, after which you simply re-approve.

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

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. Every request carries the X-Api-Key header, and every response is decrypted locally with your own key. The CLI and SDK only read and sync connections you already approved — they never establish one. An API key on its own returns ciphertext; without your private key it stays unreadable.

All of this runs for around EUR 3/month.

Does open-banking.io work with business and personal accounts?

Yes. Kreis- und Stadtsparkasse Wasserburg am Inn supports both account types through open-banking.io.

Can open-banking.io see my banking data?

No. It holds only your public key; decryption happens on your device with a key only you have.

How long does access last before renewal?

PSD2 consent runs for up to 180 days, then you re-approve on the bank's screen.
