Volksbank Mainspitze API Access & Open Banking

Reaching your Volksbank Mainspitze accounts programmatically usually means wrestling with certificates, sandbox registrations and PSD2 paperwork. open-banking.io removes that friction. It links directly to Volksbank Mainspitze (BIC GENODE51GIN) and pulls your balances and transaction history into a single dashboard — covering both business and personal accounts — while keeping every byte encrypted under a key that never leaves your device.

The service is zero-knowledge and certificate-free. open-banking.io stores only your public key, so its servers can hold your Volksbank Mainspitze data as ciphertext but can never read it. Decryption happens locally, on your machine, with a private key only you possess.

How to connect Volksbank Mainspitze

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

  1. Sign up for open-banking.io and set your encryption passphrase. Your key pair is generated right there on your own device.
  2. In the dashboard, search for Volksbank Mainspitze and choose the account type you want to link — business or personal.
  3. You are redirected to Volksbank Mainspitze'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 sync back into the dashboard. Consent stays valid for up to 180 days, after which you simply re-approve.

Access your data

Programmatic access is an optional step you take after the connection exists. Open 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. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. An API key alone only ever returns ciphertext — without your private key it stays unreadable, which is exactly the point.

All of this runs for roughly EUR 3/month, with no per-call fees or certificate renewals.

Does open-banking.io ever see my Volksbank Mainspitze login?

No. You authenticate on Volksbank Mainspitze's own consent page; open-banking.io never receives your banking credentials.

Can I read both business and personal accounts?

Yes. Volksbank Mainspitze supports both account types, and you can connect each from the dashboard.

Do I need the CLI to connect?

No. Connecting is done in the dashboard. The CLI, SDK and API only read or sync connections that already exist — there is no connect command.
