Hagnauer Volksbank API Access & Open Banking

Pulling account and transaction data out of Hagnauer Volksbank eG doesn't have to mean eIDAS certificates, a licence application or a compliance backlog. open-banking.io gives you PSD2 access to the Bodensee cooperative bank (BIC GENODE61HAG) through a single dashboard, and every figure you receive is decrypted on your own machine with a key that never leaves it. Whether you keep books for a company or track a household budget, both business and personal accounts are supported.

How to connect Hagnauer Volksbank

Connecting happens entirely in the open-banking.io dashboard — there is no API call, code snippet 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, so only you can later unlock the data.
  2. In the dashboard, search for Hagnauer Volksbank and choose the account type you need (business or personal).
  3. You're redirected to Hagnauer Volksbank's own secure login, where you approve access on the bank's PSD2 consent screen. That consent lasts up to 180 days before a quick renewal is needed.
  4. Your approved accounts sync straight back into your dashboard, ready to view.

Access your data

Once a connection exists, developers can optionally read it programmatically. 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. The CLI and SDK only read and sync connections you already made in the dashboard — they never establish new ones.

Because open-banking.io is zero-knowledge, its servers hold only your public key. An intercepted API key alone yields nothing but ciphertext. No certificates, no bank onboarding paperwork — just ~EUR 3/month.

Does open-banking.io see my Hagnauer Volksbank data?

No. Data is encrypted to your public key and decrypted only on your device. The service stores ciphertext it cannot read.

Can I connect the account with the CLI or an API key?

No. Connecting is a dashboard-only flow that redirects you to Hagnauer Volksbank's login. The CLI, SDK and API only read existing connections.

How long does access last?

Up to 180 days per consent, after which you re-approve on the bank's consent screen.
