Bankhaus Bauer API Access & Open Banking Guide

Bankhaus Bauer is a Stuttgart-based private bank, and open-banking.io lets you reach its account data without certificates, bank-specific integrations or a licence of your own. You add the bank once in a web dashboard, approve access on Bankhaus Bauer's own login, and from then on your balances and transactions sync in — ready to view or, if you write code, to pull programmatically. Everything stays private by design: open-banking.io is zero-knowledge and only ever holds your public key, so the decryption of your data happens on your device, under a key that never leaves it.

Bankhaus Bauer supports both business and personal accounts (BIC BHBADES1XXX), and a single consent stays valid for up to 180 days before you re-approve.

How to connect Bankhaus Bauer

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

  1. Sign up for open-banking.io and set an encryption passphrase. Your keys are generated locally on your own device from that passphrase.
  2. In the dashboard, search for Bankhaus Bauer and choose the account type you hold — business or personal.
  3. You are redirected to Bankhaus Bauer's own secure login, where you authenticate and grant PSD2 consent directly with the bank.
  4. Once approved, your accounts flow back into your dashboard and begin to sync. That consent runs for up to 180 days.

Access your data

After the connection exists, reading it programmatically is an optional developer step. 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), 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; without your private key, nobody — not even open-banking.io — can read it.

All of this runs at around EUR 3/month, covering 2,600+ EU and UK banks.

Do I need a developer account to connect Bankhaus Bauer?

No. Connecting is done in the dashboard by approving access on the bank's login. API keys are only for reading data afterwards.

Can open-banking.io see my Bankhaus Bauer balances?

No. It is zero-knowledge and stores only your public key. Decryption happens locally with a key you alone hold.

Up to 180 days per approval, after which you re-confirm access with the bank.
