Volksbank Sandhofen Open Banking & API Access

Reach your Volksbank Sandhofen accounts through a single, privacy-first interface. open-banking.io links to the Mannheim cooperative bank (BIC GENODE61MA3) under PSD2, covering both business and personal accounts. It is certificate-free — no eIDAS certificate or bank sponsorship to arrange — and zero-knowledge by design: your account data is encrypted and only ever decrypted on your own device with a key that never leaves it. open-banking.io holds only your public key, so it can move ciphertext but can never read a single transaction.

How to connect Volksbank Sandhofen

Connecting happens entirely in 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 key pair is generated locally on your device the moment you do.
  2. In the dashboard, search for Volksbank Sandhofen and choose the account type you want — business or personal.
  3. You are redirected to Volksbank Sandhofen's own secure login, where you approve access on the bank's consent screen. Your credentials are only ever seen by the bank.
  4. Your approved accounts sync straight back into your dashboard.

Each PSD2 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 Volksbank Sandhofen is connected, reading the data programmatically is an optional developer step. 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. An API key alone only ever returns ciphertext — without your private key, the data stays unreadable, which is exactly what zero-knowledge means.

All of this runs on the flat plan of roughly EUR 3/month, with no per-call or certificate fees.

Do I need a developer account to connect?

No. Connecting Volksbank Sandhofen is done in the dashboard by approving access on the bank's login. API keys are only for optionally reading the data afterward.

Can open-banking.io see my Volksbank Sandhofen transactions?

No. Data is decrypted only on your device with a key you alone hold. The service stores only your public key and encrypted payloads.

Which account types are supported?

Both business and personal Volksbank Sandhofen accounts can be connected, each under a consent valid for up to 180 days.
