Vereinigte Volksbanken Sindelfingen Open Banking API

Vereinigte Volksbanken eG in Sindelfingen (BIC GENODES1BBV) is a Baden-Württemberg cooperative bank with its administrative base in Böblingen, serving members across the region. If you want your own balances and transaction history in one place — or feeding a script, dashboard or accounting tool — open-banking.io gives you standards-based PSD2 access without certificates, TPP licences or messy screen-scraping. It works for both business and personal accounts, and a single consent stays valid for up to 180 days before you renew.

The key idea: your data is decrypted locally, with a key only you hold. open-banking.io stores only your public key, so its servers never see readable account data.

How to connect Vereinigte Volksbanken Sindelfingen

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

  1. Sign up at open-banking.io and set an encryption passphrase. Your keys are generated on your own device.
  2. In the dashboard, pick Vereinigte Volksbanken Sindelfingen and choose the account type (business or personal).
  3. You are redirected to Vereinigte Volksbanken Sindelfingen's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Your approved accounts sync back into your dashboard, ready to view.

That's the whole flow — you authenticate directly with the bank, never handing credentials to anyone else.

Access your data

Once a connection exists, developers can optionally read it programmatically. On the Developers page, create an API key and export a credentials.json — this bundles your API key and your private decryption key. Then use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests send an X-Api-Key header, and every response is decrypted locally with your key. The API key alone only ever returns ciphertext; without your private key, no one — not even open-banking.io — can read it. The CLI and SDK read and sync existing connections; they never create one.

Is this zero-knowledge?

Yes. Data is encrypted to your public key and decrypted only on your device. open-banking.io's servers hold no key that can read it.

Do I need a certificate or licence?

No. open-banking.io is certificate-free. You approve access through Vereinigte Volksbanken Sindelfingen's own consent screen — no eIDAS certificate or TPP registration required.
