Sparkasse Hochschwarzwald API Access & Open Banking

Sparkasse Hochschwarzwald serves the Black Forest region around Titisee-Neustadt, and open-banking.io gives you a clean, privacy-first way to reach its account data. Whether you bank as an individual or run a business (BIC SOLADES1HSW), you can pull balances and transactions into one dashboard and, if you code, read them programmatically — without certificates, screen-scraping, or handing anyone your private key.

Unlike raw PSD2 setups, open-banking.io is zero-knowledge: encryption keys are generated on your own device, and every response is decrypted locally. The service stores only your public key, so nobody — not even open-banking.io — can read your Sparkasse Hochschwarzwald data.

How to connect Sparkasse Hochschwarzwald

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 locally on your device at this moment.
  2. In the dashboard, search for Sparkasse Hochschwarzwald and choose your account type — business or personal.
  3. You are redirected to Sparkasse Hochschwarzwald's own secure login, where you approve access (PSD2 consent). Your credentials are entered only on the bank's page.
  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

After the connection is live, developers can optionally read it in code. On the Developers page, create an API key and export a credentials.json — this bundles the API key and your private decryption key. Then use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests authenticate with the X-Api-Key header, and each response is decrypted locally with your own key. The API key alone only ever returns ciphertext — without your private key, the data stays unreadable. Note there is no connect command: the CLI and SDK read and sync existing connections only.

Do I need a developer account to use Sparkasse Hochschwarzwald?

No. Connecting and viewing accounts is done in the dashboard. API keys are only for those who want programmatic access.

Can open-banking.io see my Sparkasse Hochschwarzwald transactions?

No. The architecture is zero-knowledge — data is decrypted on your device with a key only you hold.
