Volksbank Überlingen API Access & Open Banking

Reaching your Volksbank Überlingen accounts programmatically usually means wrestling with PSD2 certificates and sandbox paperwork. open-banking.io removes that overhead: it links to Volksbank Überlingen (BIC GENODE61UBE) over the regulated open-banking rails and hands you clean, decrypted account and transaction data — without ever holding the keys to it. Both business and personal accounts are supported, and a single consent stays valid for up to 180 days before you renew.

Everything is zero-knowledge. When you sign up you choose an encryption passphrase, and your key pair is generated on your own device. open-banking.io stores only your public key, so its servers physically cannot read or decrypt what flows through them — the plaintext exists only on your machine. No eIDAS certificate, no bank-by-bank onboarding.

How to connect Volksbank Überlingen

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

  1. Create an account and set your encryption passphrase (your keys are generated locally, in your browser).
  2. In the dashboard, search for Volksbank Überlingen and choose the account type you need — business or personal.
  3. You are redirected to Volksbank Überlingen's own secure login, where you approve access on the bank's PSD2 consent screen. Your credentials only ever touch the bank.
  4. Once approved, your accounts and transactions sync straight into your dashboard, refreshing until the 180-day consent expires.

Access your data

Want the data in code? That's an optional step you take after connecting. On the Developers page, create an API key and export a credentials.json — it bundles the API key with your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. The CLI and SDK only read and sync connections you already made in the dashboard — they never create one. And because the key stays with you, an API key on its own returns only ciphertext.

All of this runs for roughly EUR 3/month, covering 2,600+ EU and UK banks.

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

No. It holds only your public key; decryption happens on your device, so the service only ever sees ciphertext.

Can I connect Volksbank Überlingen from the CLI?

No — connecting is a dashboard-only flow with consent on the bank's site. The CLI just reads and syncs existing connections.

How long does access last?

Each approved consent lasts up to 180 days for both business and personal accounts, after which you re-approve on the bank's screen.
