Heidenheimer Volksbank API Access & Open Banking

Reach your Heidenheimer Volksbank accounts through a single, privacy-first workspace. open-banking.io links to the cooperative bank (BIC GENODES1HDH) under PSD2, covering both business and personal accounts, so you can view balances and transactions without juggling separate portals. It is certificate-free and zero-knowledge: your data is decrypted on your own device with a key that never leaves it, and open-banking.io only ever holds your public key.

How to connect Heidenheimer Volksbank

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 locally on your device the moment you do.
  2. In the dashboard, search for and select Heidenheimer Volksbank, then choose the account type you want to link — business or personal.
  3. You are redirected to Heidenheimer Volksbank'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's the whole flow — you authorise directly with the bank, and open-banking.io never sees your banking credentials.

Access your data

Once an account is connected, reading it programmatically is an optional developer step. Open 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 your X-Api-Key header, and every response is decrypted locally with your own key. Without that private key an API key alone returns only ciphertext, which is exactly what keeps the service zero-knowledge. All of this runs on the flat ~EUR 3/month plan.

Does open-banking.io store my Heidenheimer Volksbank password?

No. You log in and approve access on Heidenheimer Volksbank's own consent screen. open-banking.io never receives or stores your bank credentials.

Can I connect a business account?

Yes. Heidenheimer Volksbank supports both business and personal account types, selectable when you link the bank in the dashboard.

How often do I re-authorise?

PSD2 consent for Heidenheimer Volksbank runs up to 180 days. Near expiry, simply repeat the dashboard approval to keep your accounts syncing.
