Volksbank in Ostwestfalen Open Banking & API Access

Reaching the balances and transactions behind your Volksbank in Ostwestfalen accounts no longer means wrestling with bank-specific portals or paying for eIDAS certificates. open-banking.io gives you standardized PSD2 access to this Ostwestfalen-Lippe cooperative bank (BIC GENODEM1GTL), covering both business and personal accounts, alongside 2,600+ other banks across the EU and UK. The difference: your account data is decrypted locally with a key only you hold, so the service itself never sees your finances in the clear.

How to connect Volksbank in Ostwestfalen

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

  1. Sign up for an open-banking.io account and set your encryption passphrase. Your cryptographic keys are generated right there on your own device.
  2. In the dashboard, search for Volksbank in Ostwestfalen and choose the account type you need — business or personal.
  3. You are redirected to Volksbank in Ostwestfalen's own secure login, where you approve the access request (standard PSD2 consent) directly with the bank.
  4. Once approved, your accounts sync back into the dashboard. Each consent lasts up to 180 days, after which you simply re-approve on the bank's screen.

At no point does open-banking.io handle your banking credentials — authentication stays between you and Volksbank in Ostwestfalen.

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 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 CLI and SDK only read and sync connections you have already established in the dashboard — they never create one.

Because the platform is zero-knowledge, its servers store only your public key. An API key on its own returns ciphertext; without your private key, the data stays unreadable. All of this runs for roughly EUR 3 per month, with no certificate paperwork required.
