Ostfriesische Volksbank API Access & Open Banking

Reaching your Ostfriesische Volksbank data no longer means wrestling with bank APIs or PSD2 certificates. open-banking.io gives you a single, private route into the Leer-based cooperative bank (BIC GENODEF1LER), covering both business and personal accounts. Everything is encrypted end-to-end and decrypted only on your own device — our servers hold nothing but your public key, so we can never read your balances or transactions.

How to connect Ostfriesische Volksbank

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

  1. Sign up for open-banking.io and set your encryption passphrase. Your keys are generated locally, on your device, the moment you choose it.
  2. Open the dashboard and search for Ostfriesische Volksbank in the bank list, then pick the account type you need — business or personal.
  3. You are redirected to Ostfriesische Volksbank's own secure login, where you approve access on the bank's official PSD2 consent screen. This consent lasts up to 180 days before a simple renewal is required.
  4. Your approved accounts sync straight back into your dashboard, ready to view.

Nothing leaves your control: the bank authenticates you directly, and open-banking.io only ever handles data you have already encrypted.

Access your data

Want to pull Ostfriesische Volksbank data programmatically? That is an optional developer step you unlock after connecting. On the Developers page, create an API key and export a credentials.json — it 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 carry your key in the X-Api-Key header, and every response is decrypted locally with your private key. The CLI and SDK read and sync existing connections only — the bank link itself is always made in the dashboard.

At roughly EUR 3/month, you get certificate-free, zero-knowledge access without maintaining your own bank integrations.

Does open-banking.io see my Ostfriesische Volksbank data?

No. It is zero-knowledge — data is decrypted on your device with a key only you hold. Our servers store only your public key.

Can I connect using the CLI or an API key?

No. Connecting always happens in the dashboard via Ostfriesische Volksbank's own consent screen. The CLI and API only read accounts you have already connected.

How long does my access last?

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