Volksbank Ulm-Biberach API Access & Open Banking

Reaching your Volksbank Ulm-Biberach account data no longer means wrestling with eIDAS certificates or building your own PSD2 stack. open-banking.io gives you a single, certificate-free path to your balances and transactions at Volksbank Ulm-Biberach (BIC ULMVDE66XXX), covering both business and personal accounts. Everything is decrypted on your own device with a key only you hold, so the service itself never sees your financial data in the clear.

How to connect Volksbank Ulm-Biberach

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

  1. Sign up for open-banking.io and set your encryption passphrase. Your cryptographic keys are generated locally on your device at this moment.
  2. In the dashboard, pick Volksbank Ulm-Biberach from the bank list and choose the account type you need (business or personal).
  3. You are redirected to Volksbank Ulm-Biberach's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Your accounts sync straight back into your dashboard, ready to view.

Each consent lasts up to 180 days, after which you simply re-approve on the bank's screen to keep the connection live.

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 the 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 directly. 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 already made in the dashboard — they never create one.

Because open-banking.io is zero-knowledge, its servers hold only your public key and store your data as ciphertext. An API key alone returns nothing readable without your private key. All this runs for roughly EUR 3/month, across 2,600+ EU and UK banks.

Do I need an eIDAS certificate for Volksbank Ulm-Biberach?

Can open-banking.io read my Volksbank Ulm-Biberach transactions?

Does the CLI connect my bank?

No. Connecting is done in the dashboard. The CLI, SDK and API only read or sync existing connections.
