Sparkasse Staufen-Breisach API & Open Banking Access

Sparkasse Staufen-Breisach serves the Breisgau region of Baden-Württemberg, but its own banking portal was never built for exporting transactions or wiring accounts into your own tools. open-banking.io closes that gap. It gives you a single, PSD2-compliant way to reach both business and personal accounts at Sparkasse Staufen-Breisach (BIC SOLADES1STF) — and because it is zero-knowledge and certificate-free, your financial data is decrypted only on your device with a key nobody else holds.

No eIDAS certificate, no bank partnership paperwork, and no waiting on an approval queue. You set things up yourself and stay in control of every byte.

How to connect Sparkasse Staufen-Breisach

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 generated locally on your own device.
  2. In the dashboard, pick Sparkasse Staufen-Breisach and choose the account type you need — business or personal.
  3. You are redirected to Sparkasse Staufen-Breisach's own secure login, where you approve access on the bank's consent screen (standard PSD2 flow).
  4. Your approved accounts sync straight into your dashboard. Consent lasts up to 180 days, after which you simply re-approve.

Access your data

Once an account is connected, reading it programmatically is an optional developer step. 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. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key — the servers only ever hold your public key and ciphertext. The CLI and SDK read existing connections; they never connect a bank themselves.

All of this runs for around EUR 3/month.

Do I need a certificate or developer license?

No. open-banking.io is certificate-free. You sign up, set a passphrase, and approve access on Sparkasse Staufen-Breisach's login screen.

Can open-banking.io read my transactions?

No. It is zero-knowledge. Data is decrypted on your device with a key only you hold; the service stores only your public key and encrypted data.

Does an API key alone return my data?

No. Without your private decryption key from credentials.json, an API key returns only ciphertext you cannot read.
