Sparkasse Bad Hersfeld-Rotenburg Open Banking API Access

Reaching your Sparkasse Bad Hersfeld-Rotenburg account data no longer means wrestling with eIDAS certificates or a bank sandbox. open-banking.io gives you PSD2-grade access to this Hessian Sparkasse (BIC HELADEF1HER) covering both business and personal accounts, with a single subscription and no compliance paperwork of your own.

The service is zero-knowledge by design: encryption keys are generated on your device and never leave it. open-banking.io holds only your public key, so its servers store ciphertext they cannot read — your balances and transactions are decrypted locally, under a passphrase only you know.

How to connect Sparkasse Bad Hersfeld-Rotenburg

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 key pair is created right there in your browser.
  2. In the dashboard, search for Sparkasse Bad Hersfeld-Rotenburg and choose the account type you need — business or personal.
  3. You are redirected to Sparkasse Bad Hersfeld-Rotenburg's own secure login, where you approve access on the bank's PSD2 consent screen. Consent lasts up to 180 days before you renew it.
  4. Your approved accounts sync back into the dashboard, ready to view.

That is the whole flow — you authenticate directly with the bank, and open-banking.io never sees your credentials.

Access your data

Once a connection exists, 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 with your private decryption key. From there:

  • Use the CLI: openbanking accounts, openbanking transactions, openbanking sync.
  • Or call the REST API / SDK, passing your key in the X-Api-Key header.

Every response arrives encrypted and is decrypted locally with your private key. An API key on its own returns only ciphertext — the readable data never exists on a server. Note the CLI and SDK only read and sync existing connections; there is no connect command.
