Volksbank Braunlage Open Banking & API Access

Pulling your Volksbank Braunlage balances and transactions into your own tools usually means wrestling with PSD2 certificates and bank-specific paperwork. open-banking.io removes that friction: it links to Volksbank Braunlage (BIC GENODEF1BLG) as one of 2,600+ EU/UK institutions, and your financial data is decrypted locally with a key that never leaves your device. It works for both business and personal accounts, with consent lasting up to 180 days before you renew.

The service is zero-knowledge and certificate-free. Our servers only ever hold your public key, so we cannot read or decrypt anything you sync — the plaintext exists only on your machine.

How to connect Volksbank Braunlage

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 keys are generated right there on your own device.
  2. In the dashboard, choose Volksbank Braunlage and select the account type you want to link (business or personal).
  3. You're redirected to Volksbank Braunlage's own secure login, where you approve access on their official PSD2 consent screen.
  4. Once approved, your accounts sync back into your dashboard, and balances and transactions appear ready to use.

Because approval happens on the bank's own site, your credentials are only ever entered at Volksbank Braunlage — never shared with us.

Access your data

After the connection exists, developers can optionally read it programmatically. 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 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 it's unreadable. Note the CLI and SDK only read and sync connections that already exist; they never create one.

All of this runs for about EUR 3/month.

Do I need an eIDAS certificate?

No. open-banking.io is certificate-free — you just approve access on Volksbank Braunlage's consent screen.

Can open-banking.io see my transactions?

No. It's zero-knowledge: we store only your public key, and decryption happens on your device with a key only you hold.

How often do I re-authorise?

Volksbank Braunlage consent lasts up to 180 days, after which you re-approve from the dashboard to keep syncing.
