Sparkasse Hochrhein Open Banking & API Access

Reaching your Sparkasse Hochrhein balances and transactions no longer means scraping statements or wrestling with certificates. open-banking.io gives you a single, encrypted view of your accounts (BIC SKHRDE6WXXX) that you set up entirely from a web dashboard. Both business and personal accounts are supported, and because the whole platform is zero-knowledge, every figure is decrypted on your own device with a key only you hold.

How to connect Sparkasse Hochrhein

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

  1. Sign up for an open-banking.io account.
  2. Set an encryption passphrase. Your keys are generated locally on your device, so open-banking.io never sees them.
  3. In the dashboard, search for Sparkasse Hochrhein and choose your account type — business or personal.
  4. You are redirected to Sparkasse Hochrhein's own secure login, where you approve access under PSD2. This consent lasts up to 180 days before you renew it.
  5. Your accounts sync back into the dashboard, ready to view.

That is the entire connection flow — you approve on the bank's screen, and open-banking.io stores only encrypted data behind your public key.

Access your data

Once Sparkasse Hochrhein is connected, developers can optionally read the data programmatically. On the Developers page, create an API key and export a credentials.json file, which bundles that API key together with your private decryption key. From there you can 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 API key by itself only ever returns ciphertext. There is no connect command; the tooling reads and syncs the connection you already approved in the dashboard.

All of this — unlimited connections, dashboard sync and developer access across 2,600+ EU and UK banks — runs at around EUR 3 per month, with no eIDAS certificate or bank partnership required.
