Volksbank Sauerland Open Banking & API Access

Pulling your Volksbank Sauerland account data into your own tools shouldn't mean juggling eIDAS certificates or bespoke bank integrations. open-banking.io gives you PSD2-compliant read access to Volksbank Sauerland (BIC GENODEM1SMA) across a single dashboard that already speaks to 2,600+ European banks. Both business and personal accounts are supported, and each consent stays valid for up to 180 days before you re-approve.

What makes it different is the trust model: it is zero-knowledge. Your encryption keys are generated on your own device from a passphrase only you know, so the balances and transactions that flow through open-banking.io are decrypted locally — the service only ever holds your public key and never sees your data in the clear.

How to connect Volksbank Sauerland

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

  1. Sign up for an open-banking.io account.
  2. Set your encryption passphrase; your personal keys are generated right there on your device.
  3. In the dashboard, pick Volksbank Sauerland and choose the account type — business or personal.
  4. You're redirected to Volksbank Sauerland's own secure login to approve access on their PSD2 consent screen.
  5. Once you confirm, your accounts sync back into the dashboard and stay up to date for the life of the 180-day consent.

You never hand your banking credentials to open-banking.io — approval always happens on the bank's own page.

Access your data

Already connected and want to work with the data programmatically? That's an optional developer step. From the Developers page, create an API key and export a credentials.json file — this bundles the API key together with your private decryption key. From there you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API directly. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key — an API key alone only ever returns ciphertext. The CLI and SDK read and sync your existing connection; they don't create it.

All of this runs on flat pricing of roughly EUR 3/month, with no certificates to buy or renew.
