VR-MainBank API Access & Open Banking Integration

Pulling account and transaction data from VR-MainBank no longer means wrestling with bank certificates or building a PSD2 stack from scratch. open-banking.io connects to VR-MainBank (BIC GENODEF1GZH) as one of 2,600+ supported EU and UK institutions, covering both business and personal accounts. Because the platform is zero-knowledge, your financial data is decrypted on your own device with a key only you hold — open-banking.io's servers only ever store your public key and encrypted payloads.

That means no eIDAS certificates, no bespoke integration work, and no vendor sitting in the middle able to read your statements. You get a clean, synced view of your VR-MainBank accounts for around EUR 3/month.

How to connect VR-MainBank

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 open the web dashboard.
  2. Set an encryption passphrase. Your key pair is generated locally on your device, so only you can ever unlock the data.
  3. Pick VR-MainBank from the bank list and choose the account type — business or personal.
  4. Approve on VR-MainBank's own login. You're redirected to the bank's secure consent screen to authorise access under PSD2. Consent lasts up to 180 days, after which you simply re-approve.
  5. Your VR-MainBank accounts sync back into the dashboard, ready to view.

Access your data

Once a connection exists, developers can optionally read it programmatically. From 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.

Every request carries 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. Note that the CLI and SDK only read and sync connections you've already made in the dashboard; there's no connect command.

FAQ

Do I need a certificate to access VR-MainBank?

No. open-banking.io is certificate-free. You authorise access on VR-MainBank's own consent screen and the platform handles the PSD2 plumbing.

Can open-banking.io read my VR-MainBank data?

No. It's zero-knowledge — data is decrypted only on your device with a key open-banking.io never holds.

How long does access last?

VR-MainBank grants consent for up to 180 days per authorisation, then you re-approve from the dashboard.
