Sparkasse Bad Tölz-Wolfratshausen API & Open Banking Access

Reading your Sparkasse Bad Tölz-Wolfratshausen accounts programmatically no longer means chasing bank certificates or building a PSD2 stack yourself. open-banking.io gives you a single, secure route into the Bavarian savings bank (BIC BYLADEM1WOR), covering both business and personal account types, with balances and transactions flowing straight into your dashboard.

The design principle is zero-knowledge: your data is decrypted locally, using an encryption key that only ever exists on your own device. open-banking.io's servers hold your public key alone — they can never read or decrypt what syncs from your bank.

How to connect Sparkasse Bad Tölz-Wolfratshausen

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 device.
  2. In the dashboard, choose Sparkasse Bad Tölz-Wolfratshausen and select the account type you want to link (business or personal).
  3. You're redirected to Sparkasse Bad Tölz-Wolfratshausen's own secure login, where you approve access on the bank's PSD2 consent screen. Your credentials go only to the bank.
  4. Your accounts sync back into the dashboard automatically. Consent lasts up to 180 days, after which you simply re-approve.

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 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. Requests carry the X-Api-Key header, and every response is decrypted locally with your own key — an API key on its own only ever returns ciphertext. Note the CLI and SDK read and sync existing connections; they never create one.

All of this runs certificate-free for roughly EUR 3/month.

Do I need a developer account to connect?

No. Linking Sparkasse Bad Tölz-Wolfratshausen is a dashboard task. API keys and credentials.json matter only if you later want to pull data into your own code.

Can open-banking.io see my banking data?

No. It's zero-knowledge — the service stores only your public key, so decryption happens exclusively on your device.

Which accounts are supported?
