CVW-Privatbank API Access & Open Banking Data

Pulling your CVW-Privatbank balances and transactions into your own tools no longer means wrestling with bank certificates or a PSD2 sandbox. open-banking.io gives you a single, privacy-first path to your CVW-Privatbank data (BIC GENODEF1WHD), covering both business and personal accounts, with a consent that stays valid for up to 180 days before you re-authorise.

CVW-Privatbank is one of 2,600+ EU and UK institutions reachable through the service, and every byte you retrieve is decrypted locally with a key that never leaves your device.

How to connect CVW-Privatbank

Connecting happens entirely inside 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 dashboard.
  2. Set an encryption passphrase. Your key pair is generated on your own device; open-banking.io only ever holds your public key.
  3. Pick CVW-Privatbank from the bank list and choose the account type — business or personal.
  4. You're redirected to CVW-Privatbank's own secure login, where you approve access on the bank's PSD2 consent screen.
  5. Once approved, your CVW-Privatbank accounts sync into your dashboard automatically.

That's the whole connection. Nothing about your CVW-Privatbank credentials passes through open-banking.io — you authenticate directly with the bank.

Access your data

Want to read the data programmatically? That's an optional developer step, taken only after the bank is connected. On 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 you can use the CLI:

openbanking accounts
openbanking transactions
openbanking sync

...or the SDK or REST API. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. The API key alone only ever returns ciphertext — without your private key, the data stays unreadable.

This is what zero-knowledge, certificate-free access means: no eIDAS certificate to buy, no server that can read your CVW-Privatbank statements, all for around EUR 3/month.

Do I connect CVW-Privatbank with an API key?

No. You connect in the dashboard by approving access on CVW-Privatbank's own login screen. API keys are only for reading data afterwards.

Can open-banking.io see my CVW-Privatbank data?

No. It holds only your public key; decryption happens on your device with a private key you alone control.

Up to 180 days for CVW-Privatbank, after which you simply re-approve access in the dashboard.
