Oldenburger Volksbank API Access & Open Banking

Pulling your Oldenburger Volksbank balances and transactions into your own tools shouldn't mean juggling eIDAS certificates or a PSD2 licence. open-banking.io gives you a single, secure path to your Oldenburger Volksbank data (BIC GENODEF1EDE) for both business and personal accounts — and because it is zero-knowledge and certificate-free, everything is decrypted on your device with a key only you hold.

How to connect Oldenburger Volksbank

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, so open-banking.io only ever stores your public key.
  2. In the dashboard, search for Oldenburger Volksbank and choose the account type you need — business or personal.
  3. You are redirected to Oldenburger Volksbank's own secure login, where you approve access under PSD2. open-banking.io never sees your banking credentials.
  4. Your consent stays valid for up to 180 days, after which you simply re-approve on the bank's screen.

Once approved, your Oldenburger Volksbank accounts sync straight into the dashboard, ready to view.

Access your data

Want the data in your own code? That's an optional developer step, taken after the connection above exists. 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, read your synced accounts with the CLI:

openbanking accounts
openbanking transactions
openbanking sync

…or use an SDK or the REST API directly, sending your key in the X-Api-Key header. Every response arrives encrypted and is decrypted locally with your private key. The CLI and SDK only read and refresh connections you already made in the dashboard — they never create one.

At around EUR 3/month, you get ongoing access without infrastructure or compliance overhead.

Can open-banking.io read my Oldenburger Volksbank data?

No. It holds only your public key, so data stays ciphertext on its servers. Decryption happens on your device alone.

Does the API key alone return readable transactions?

No. An API key fetches ciphertext. Without the private key inside your credentials.json, the response can't be decrypted.

Do I need a certificate or PSD2 licence?

No. open-banking.io is certificate-free — you approve access through Oldenburger Volksbank's standard consent screen, nothing more.
