Bernhauser Bank API Access & Open Banking Guide

Reaching your Bernhauser Bank data no longer means wrestling with PSD2 certificates, sandbox onboarding, or eIDAS paperwork. open-banking.io gives you read access to Bernhauser Bank (BIC GENODES1BBF) accounts through a single dashboard, covering both business and personal account types. Everything is encrypted end to end and decrypted on your own device with a key only you hold — the service itself is zero-knowledge and never sees your statements in the clear.

Bernhauser Bank, a cooperative bank in the Filderstadt/Bernhausen area near Stuttgart, participates in the European open-banking framework. That means you can grant consent for up to 180 days at a time before a quick re-approval keeps the connection alive.

How to connect Bernhauser Bank

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; only your public key ever leaves it.
2. In the dashboard, search for Bernhauser Bank and choose the account type you want to link — business or personal.
3. You are redirected to Bernhauser Bank's own secure login, where you approve access on the bank's PSD2 consent screen.
4. Once approved, your accounts and transactions sync back into your dashboard, ready to view.

That's the whole flow. No developer redirect, no certificate upload, no waiting on a bank sandbox.

Access your data

After a connection exists, developers can optionally read it programmatically. On the Developers page, create an API key and export a credentials.json — this bundles your 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. The API key alone only ever returns ciphertext, so even a leaked key exposes nothing readable. The CLI and SDK read and sync existing connections — they never create one.

All of this runs on flat pricing of roughly EUR 3/month, with no per-call fees.

Do I need a PSD2 certificate for Bernhauser Bank?
