Volksbank Stendal API Access & Open Banking Data

Reaching your Volksbank Stendal account data no longer means scraping statements or wrestling with bank-specific software. open-banking.io gives you PSD2-based access to this Saxony-Anhalt cooperative bank (BIC GENODEF1SDL) across both business and personal account types, with everything decrypted on your own device using a key only you hold.

Because the platform is certificate-free and zero-knowledge, you don't register an eIDAS certificate or run a bank connector. You approve access once on Volksbank Stendal's own login, and your balances and transactions flow into a dashboard nobody but you can read.

How to connect Volksbank Stendal

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 an open-banking.io account.
  2. Set your encryption passphrase. Your keys are generated locally on your device, so the platform only ever stores your public key.
  3. In the dashboard, search for Volksbank Stendal and choose your account type (business or personal).
  4. You're redirected to Volksbank Stendal's own secure login to approve access. This is the standard PSD2 consent screen — you authenticate directly with the bank.
  5. Your accounts sync back into the dashboard, ready to view.

Consent lasts up to 180 days, the maximum window Volksbank Stendal permits, after which you simply re-approve to keep the connection live.

Access your data

Once a connection exists, developers can optionally read it programmatically. On 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.
  • Or call the REST API / SDK, passing your key in the X-Api-Key header.

Every response is ciphertext until it's decrypted locally with your private key. An API key alone returns unreadable data — the servers can't decrypt anything. The CLI and SDK only read and sync existing connections; they never create one.

All of this runs at around EUR 3/month.

Do I need a certificate to connect Volksbank Stendal?

No. open-banking.io is certificate-free. You only approve consent on the bank's own login screen.

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

No. It's zero-knowledge — data is encrypted with your key and decrypted only on your device.

Does the API key alone let me read data?

No. Without your private decryption key from credentials.json, requests return only encrypted content.
