Volksbank Rhein-Ruhr API Access & Open Banking Data

Reach your Volksbank Rhein-Ruhr accounts through a single, privacy-first workflow. open-banking.io links to the Duisburg-based cooperative bank (BIC GENODED1VRR) under PSD2, covering both business and personal account types. It is certificate-free and zero-knowledge: your data is decrypted on your own device with a key only you hold, so open-banking.io servers never see readable balances or transactions. No eIDAS certificate, no bank sponsorship, and no developer paperwork stand between you and your own account data — just a straightforward dashboard connection for roughly EUR 3/month.

How to connect Volksbank Rhein-Ruhr

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 generated locally on your device; only your public key ever leaves it.
  2. In the dashboard, search for Volksbank Rhein-Ruhr and choose the account type you need (business or personal).
  3. You are redirected to Volksbank Rhein-Ruhr's own secure login and consent screen, where you approve access directly with the bank.
  4. Your approved accounts sync back into your dashboard. Consent lasts up to 180 days, after which you simply re-approve on the bank's screen.

Because approval is granted on Volksbank Rhein-Ruhr's own page, your banking credentials are never shared with open-banking.io.

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), an SDK, or the REST API. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. Without that private key, the payload stays ciphertext — even to you. The CLI and SDK only read and sync existing connections; there is no connect command.
