Volksbank Ermstal-Alb API Access & Open Banking

Reaching your Volksbank Ermstal-Alb account data no longer means wrestling with certificates, sandbox registrations, or a PSD2 licence of your own. open-banking.io gives you a single, privacy-first path to your balances and transactions at this Metzingen-based cooperative bank (BIC GENODES1MTZ), covering both business and personal accounts. Everything is decrypted on your own device with a key that never leaves it — the service holds only your public key and can never read your statements.

How to connect Volksbank Ermstal-Alb

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

  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, search for and select Volksbank Ermstal-Alb, then choose the account type you want to link (business or personal).
  3. You are redirected to Volksbank Ermstal-Alb's own secure login, where you approve access on the bank's PSD2 consent screen — your credentials are only ever entered on the bank's site.
  4. Once approved, your accounts sync into your dashboard. Consent lasts up to 180 days, after which you simply re-approve on the bank's screen.

Access your data

Programmatic access is an optional step you take after connecting. From the Developers page, create an API key and export a credentials.json — this bundles the API key together with your private decryption key. You can then 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. An API key alone only ever returns ciphertext; without your private key, no one — including open-banking.io — can read it. Note the CLI and SDK only read and sync connections that already exist; they cannot create the bank link itself.

At roughly EUR 3/month, you get certificate-free, zero-knowledge access across 2,600+ EU and UK banks from one account.

Is my Volksbank Ermstal-Alb login shared with open-banking.io?

No. You enter your credentials only on Volksbank Ermstal-Alb's own consent page. open-banking.io never sees them.

Which account types are supported?

Both business and personal Volksbank Ermstal-Alb accounts (BIC GENODES1MTZ) can be linked and synced.

Each approval is valid for up to 180 days, the PSD2 maximum, after which you re-approve on the bank's screen.
