VR VerbundBank API Access & Open Banking Data

Reaching your VR VerbundBank account data no longer means chasing eIDAS certificates or building a bespoke PSD2 stack. open-banking.io gives you a single, certificate-free path to the Hessen co-operative bank (BIC GENODE51ALS), covering both business and personal accounts. Balances and transactions land in your dashboard, encrypted so that only you — never our servers — can read them.

Because open-banking.io is zero-knowledge, your keys are generated on your own device and we hold only your public key. That keeps VR VerbundBank data private end to end while still letting you sync it wherever you need it, all for roughly EUR 3/month across 2,600+ supported European banks.

How to connect VR VerbundBank

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 open the web dashboard.
  2. Set your encryption passphrase. Your personal keys are created locally on your device; the passphrase never leaves it.
  3. Pick VR VerbundBank from the bank list and choose the account type — business or personal.
  4. Approve access on VR VerbundBank's own login. You are redirected to the bank's secure consent screen, where you authenticate directly and grant PSD2 access for up to the 180-day maximum consent window.
  5. Your accounts sync back into the dashboard automatically, ready to view or export.

When the 180 days lapse, simply repeat the approval to refresh consent.

Access your data

Programmatic access is an optional developer step you take after the bank is connected. From the Developers page, create an API key and export a credentials.json — it 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. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. An API key on its own only returns ciphertext — without your private key the data stays unreadable, even to us.

FAQ

Do I need a certificate to connect VR VerbundBank?

No. open-banking.io is certificate-free. You only sign up, set a passphrase, and approve access on VR VerbundBank's own login screen.

Can I connect the account with the CLI or API key?

No. Connecting is done in the dashboard via the bank's consent screen. The CLI, SDK, and API only read or sync accounts you have already connected.

Can open-banking.io staff see my VR VerbundBank data?

No. The service is zero-knowledge — we hold only your public key, and every response is decrypted locally with a private key that only you possess.
