Kreissparkasse Traunstein-Trostberg Open Banking API

Pulling your Kreissparkasse Traunstein-Trostberg balances and transactions into your own tools no longer means chasing eIDAS certificates or filing a PSD2 licence. open-banking.io gives you compliant, read-only access to the Bavarian Kreissparkasse (BIC BYLADEM1TST) across both business and personal accounts, while keeping every byte encrypted under a key that never leaves your device.

The service is zero-knowledge and certificate-free. open-banking.io stores only your public key, so its servers can relay ciphertext but can never read or decrypt your Kreissparkasse Traunstein-Trostberg statements. With 2,600+ EU and UK banks covered for roughly EUR 3/month, it is aimed at people who want their bank data without surrendering their privacy.

How to connect Kreissparkasse Traunstein-Trostberg

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 keys are generated locally, on your own device.
  2. In the dashboard, pick Kreissparkasse Traunstein-Trostberg and choose the account type — business or personal.
  3. You are redirected to Kreissparkasse Traunstein-Trostberg's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Your accounts sync back into the dashboard. Consent lasts up to 180 days, after which you simply re-approve on the bank's screen.

Access your data

Once the connection is live, reading it programmatically is an optional developer step. Open 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 CLI and SDK only read and sync connections you already approved — there is no connect command.

Do I need an eIDAS certificate?

No. open-banking.io is certificate-free. You authorise access directly on Kreissparkasse Traunstein-Trostberg's consent screen — no QWAC or licensing paperwork.

Can open-banking.io see my transactions?

No. It is zero-knowledge and holds only your public key. Data is decrypted on your device, so an API key alone returns ciphertext without your private key.

Does this work for business accounts?

Yes. Both business and personal Kreissparkasse Traunstein-Trostberg accounts are supported under a single subscription.
