Volksbank Bodensee-Oberschwaben API & Open Banking Access

Reaching account and transaction data from Volksbank Bodensee-Oberschwaben eG doesn't need to mean chasing bank certificates or building a PSD2 stack from scratch. open-banking.io gives you a single, standardised path to this Baden-Württemberg cooperative bank (BIC GENODES1TET), covering both business and personal accounts under a consent that stays valid for up to 180 days before renewal.

The defining feature is trust: open-banking.io is zero-knowledge. Your encryption keys are generated on your own device, and the service only ever stores your public key. Data flowing back from Volksbank Bodensee-Oberschwaben is decrypted locally, so nobody — not even open-banking.io's servers — can read your balances or statements.

How to connect Volksbank Bodensee-Oberschwaben

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 an open-banking.io account.
  2. Set your encryption passphrase; your private key is created locally and never leaves your device.
  3. In the dashboard, search for and select Volksbank Bodensee-Oberschwaben, then choose whether you're linking a business or personal account.
  4. You're redirected to Volksbank Bodensee-Oberschwaben's own secure login, where you approve access on the bank's PSD2 consent screen.
  5. Your accounts sync straight into your dashboard.

Credentials stay with the bank throughout — you authenticate on Volksbank Bodensee-Oberschwaben's own pages, never inside a third-party form.

Access your data

Once a connection is live, 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 directly. Requests carry the X-Api-Key header, and each response is decrypted locally with your own key. An API key on its own returns only ciphertext, which keeps the zero-knowledge guarantee intact. Note there is no connect command — the tooling reads and syncs existing links only.

All of this runs at roughly EUR 3/month, certificate-free.

Is a developer account required?

No. The dashboard connection works on its own. API keys and credentials.json are only for programmatic access.

Can open-banking.io read my Volksbank Bodensee-Oberschwaben data?

No. It holds only your public key; decryption happens on your device.

Up to 180 days, after which you re-approve on the bank's consent screen.
