Volksbank Grebenhain API Access & Open Banking Data

Reach your Volksbank Grebenhain account data through a single, privacy-first workflow. open-banking.io links to Volksbank Grebenhain (BIC GENODE51GRC) using regulated PSD2 access, so you can view balances and transactions for both business and personal accounts without handling eIDAS certificates or storing anything sensitive on someone else's server. Everything you retrieve is decrypted on your own device with a key that never leaves it — the platform only ever holds your public key.

How to connect Volksbank Grebenhain

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 key pair is generated locally on your device at this moment.
  2. In the dashboard, search for Volksbank Grebenhain and choose the account type you want to link — business or personal.
  3. You are redirected to Volksbank Grebenhain's own secure login, where you approve the access request (standard PSD2 consent) directly with the bank.
  4. Once approved, your selected accounts sync back into your dashboard, ready to view.

Your consent stays valid for up to 180 days, after which you simply repeat the approval on the bank's screen to keep the connection alive.

Access your data

Programmatic access is an optional step you take after an account is connected. 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. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. Without that private key, an API key alone returns only ciphertext — which is exactly what zero-knowledge means.
