Sparda-Bank Ostbayern API Access & Open Banking

Sparda-Bank Ostbayern (BIC GENODEF1S05) is the Regensburg-based cooperative bank serving eastern Bavaria, and open-banking.io lets you reach its account and transaction data without EIDAS certificates, sandbox paperwork or a custom PSD2 integration. Whether you run a business or a personal account, you connect once and keep a clean, ready-to-query view of your finances.

open-banking.io is a zero-knowledge service covering 2,600+ European banks. Your encryption keys are generated on your own device, so the platform stores only your public key and can never read your statements — decryption always happens locally, under a passphrase only you hold.

How to connect Sparda-Bank Ostbayern

Connecting is done entirely in the open-banking.io dashboard — there is no API call, code or key involved in linking the bank:

  1. Sign up for an open-banking.io account.
  2. Set your encryption passphrase; your private key is created locally and never leaves your device.
  3. In the dashboard, search for Sparda-Bank Ostbayern and choose your account type — business or personal are both supported.
  4. You are redirected to Sparda-Bank Ostbayern's own secure login, where you approve PSD2 access on the bank's consent screen.
  5. Your accounts sync back into the dashboard, and the consent stays valid for up to 180 days before you re-approve.

Access your data

Programmatic access is an optional step you take after the connection exists. 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 you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API directly. Requests carry your key in the X-Api-Key header, and every response is decrypted locally with your own key. An API key on its own only ever returns ciphertext; without your private key, nobody — not even open-banking.io — can read the contents.

At around EUR 3 per month, you get certificate-free, privacy-first access without maintaining banking infrastructure yourself.

No. Linking happens in the dashboard through the bank's login. Developer tools are only for reading data once a connection is live.

Sparda-Bank Ostbayern grants up to 180 days per approval. After that you simply re-confirm access from the dashboard.

Can open-banking.io see my transactions?

No. It holds only your public key. All data is encrypted end-to-end and decrypted locally with the private key you control.
