Volksbank Überherrn API Access & Open Banking

Reaching your Volksbank Überherrn accounts from your own software usually means wrestling with PSD2 certificates and bank-specific sandboxes. open-banking.io removes that hurdle. It is a certificate-free bridge to 2,600+ EU and UK banks, and it treats Volksbank Überherrn (BIC GENODE51UBH) as a first-class connection covering both business and personal accounts. Because the platform is zero-knowledge, your financial data is encrypted the moment it arrives and can only be decrypted on your own device with a key that never leaves it.

How to connect Volksbank Überherrn

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

  1. Sign up for open-banking.io and set your encryption passphrase. Your keypair is generated locally, so the service only ever holds your public key.
  2. In the dashboard, search for Volksbank Überherrn and choose whether you are linking a business or personal account.
  3. You are redirected to Volksbank Überherrn's own secure login, where you approve access on the bank's official PSD2 consent screen.
  4. Your accounts and transactions then sync back into your dashboard automatically.

The consent you grant lasts up to 180 days, after which you simply re-approve on the bank's screen to keep the connection live.

Access your data

Once Volksbank Überherrn is connected, developers can optionally read the data programmatically. Open the Developers page, create an API key, and export a credentials.json — this bundles your 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. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. An API key alone only ever returns ciphertext, so nobody — not even open-banking.io — can read your accounts server-side.

All of this runs for roughly EUR 3/month, with no eIDAS certificate and no bank onboarding paperwork.

Do I need a QWAC or PSD2 certificate?

No. open-banking.io is certificate-free; you authorise directly on Volksbank Überherrn's consent screen.

Can the CLI connect my Volksbank Überherrn account?

No. The CLI and SDK only read and sync existing connections. Linking a bank always happens in the dashboard.

Can open-banking.io see my balances?

No. It stores only your public key, so data stays encrypted until your device decrypts it.
