Volksbank Backnang API Access & Open Banking Data

Reaching your Volksbank Backnang accounts programmatically no longer means chasing bank certificates or building a PSD2 stack yourself. open-banking.io gives you a single, standardised path to your Volksbank Backnang data — balances, transactions and account details — across both business and personal accounts (BIC GENODES1VBK). Every payload is encrypted end to end and decrypted locally with a key only you hold, so the service is zero-knowledge and certificate-free by design.

How to connect Volksbank Backnang

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 open the web dashboard.
  2. Set your encryption passphrase. Your key pair is generated on your own device; open-banking.io only ever sees your public key.
  3. Pick Volksbank Backnang from the bank list and choose the account type you want — business or personal.
  4. Approve on Volksbank Backnang's own login. You are redirected to the bank's secure consent screen to grant PSD2 access directly. open-banking.io never sees your banking credentials.
  5. Your accounts sync back into the dashboard, ready to view. A single consent stays valid for up to 180 days before Volksbank Backnang asks you to re-authorise.

Access your data

Once the connection is live, developers can optionally read it programmatically. On the Developers page, create an API key and export a credentials.json — this bundles the API key and your private decryption key. From there 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. The CLI and SDK only read and sync connections you already made in the dashboard — there is no connect command.

All of this runs for around EUR 3/month, with no per-certificate fees.

Do I need an eIDAS certificate for Volksbank Backnang?

No. open-banking.io is certificate-free — the PSD2 consent you approve on the bank's screen is all that's required.

Can open-banking.io read my Volksbank Backnang transactions?

No. It stores only your public key, so data on its servers stays encrypted ciphertext. Only your private key, held on your device, can decrypt it.

Does an API key alone return readable data?

No. Without your private decryption key you receive ciphertext. credentials.json pairs the X-Api-Key with your key so decryption happens locally.
