Volksbank Südheide - Isenhagener Land - Altmark API access

Reaching your Volksbank Südheide - Isenhagener Land - Altmark accounts programmatically usually means wrestling with PSD2 certificates and a licensing process. open-banking.io removes that: it is a certificate-free bridge to 2,600+ EU and UK banks, and every balance and transaction is decrypted on your own device with a key only you hold. The service never sees your statements in the clear — it stores only your public key, so it is zero-knowledge by design.

Whether you run a business current account or a private one, this Hermannsburg-based cooperative (BIC GENODEF1HMN) is reachable through the same simple, self-service flow.

How to connect Volksbank Südheide - Isenhagener Land - Altmark

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 an open-banking.io account.
  2. Set an encryption passphrase. Your key pair is generated locally on your device, so only you can later unlock the data.
  3. In the dashboard, search for Volksbank Südheide - Isenhagener Land - Altmark and choose the account type you need — business or personal.
  4. You are redirected to Volksbank Südheide - Isenhagener Land - Altmark's own secure login, where you approve access on the bank's PSD2 consent screen. Consent lasts up to 180 days before you renew it.
  5. Your approved accounts sync straight into your dashboard.

Access your data

Reading the data programmatically is an optional step for developers, done only after the connection above exists. On the Developers page, create an API key and export a credentials.json — it bundles that API key together with your private decryption key. From there you can 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. The CLI and SDK only read and sync existing connections; they never create one. Without your private key, an API key alone returns nothing but ciphertext.

All of this runs at around EUR 3/month, flat.

Does open-banking.io store my banking password?

No. You authenticate directly on Volksbank Südheide - Isenhagener Land - Altmark's own login page. open-banking.io never receives your credentials.

Can I connect both business and personal accounts?

Yes. Both account types are supported — pick the one you want when selecting the bank, and repeat the flow for the other.

How long does access stay active?

Up to 180 days per consent, matching the bank's PSD2 window. Renew from the dashboard when it expires.
