Volksbank Kempen-Grefrath API Access & Open Banking

Reach your Volksbank Kempen-Grefrath account data without wrestling with PSD2 certificates or hosting your own bank interface. open-banking.io links to the co-op bank (BIC GENODED1KMP) and streams your business and personal account details and transactions into one dashboard — encrypted so that only you can read them. It is a zero-knowledge service: your decryption key is generated on your own device, and open-banking.io only ever holds your public key.

How to connect Volksbank Kempen-Grefrath

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

  1. Sign up for open-banking.io and set an encryption passphrase. Your keys are created locally, on your device.
  2. In the dashboard, search for Volksbank Kempen-Grefrath and choose the account type you hold — business or personal.
  3. You are redirected to Volksbank Kempen-Grefrath's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Your accounts sync back into the dashboard. Consent lasts up to 180 days, after which you simply re-approve.

Because you authenticate directly with the bank, open-banking.io never sees your banking credentials.

Access your data

If you build software, reading the data programmatically is an optional step you take after connecting. On the Developers page, create an API key and export a credentials.json — this 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 carry the X-Api-Key header, and every response is decrypted locally with your own key. An API key alone returns only ciphertext, which keeps the whole pipeline zero-knowledge.

All of this — dashboard sync plus developer access — runs at roughly EUR 3/month, with no eIDAS certificate to buy or renew.

Is my Volksbank Kempen-Grefrath data private?

Yes. Data is decrypted only on your device with a key you alone hold. open-banking.io's servers store just your public key and cannot read your accounts.

Can I connect using the CLI or an API key?

No. Connecting is done in the dashboard by approving access on Volksbank Kempen-Grefrath's login page. The CLI, SDK, and API only read or sync connections that already exist.

Which accounts are supported?

Both business and personal Volksbank Kempen-Grefrath accounts, with consent valid for up to 180 days per approval.
