Volksbank Rhein-Erft-Köln Open Banking & API Access

Pulling account and transaction data out of Volksbank Rhein-Erft-Köln (BIC GENODED1FHH) usually means wrestling with certificates and PSD2 paperwork. open-banking.io removes that: it is a certificate-free, zero-knowledge bridge covering 2,600+ European banks, so you reach both business and personal accounts at this Rhine-Erft cooperative through one consistent dashboard — and everything is decrypted on your own machine.

How to connect Volksbank Rhein-Erft-Köln

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

  1. Sign up and set your encryption passphrase. Your keys are generated locally on your device; open-banking.io never sees the private half.
  2. In the dashboard, search for Volksbank Rhein-Erft-Köln and choose the account type you need — business or personal.
  3. You are redirected to Volksbank Rhein-Erft-Köln'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 is the whole flow — you authenticate with the bank directly, never handing credentials to anyone else.

Access your data

Once accounts are connected, developers can optionally read them programmatically. Open the Developers page, create an API key, and export a credentials.json bundling that key with your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Calls send the X-Api-Key header, and every response is decrypted locally with your own key. The CLI and SDK only read and sync connections that already exist — they cannot create new ones.

Because open-banking.io holds only your public key, its servers physically cannot read your Volksbank Rhein-Erft-Köln balances. An API key alone returns ciphertext; without your private key it stays unreadable. All of this runs for around EUR 3 per month.

Does open-banking.io store my banking password?

No. You log in on Volksbank Rhein-Erft-Köln's own consent page, so your credentials never touch open-banking.io.

Can I connect both business and personal accounts?

Yes. Volksbank Rhein-Erft-Köln supports both account types — add each one separately from the dashboard.

PSD2 consent runs up to 180 days. When it lapses, reauthorize in the dashboard to keep syncing.
