Hüttenberger Bank API Access & Open Banking Data

Reaching your Hüttenberger Bank accounts programmatically no longer means chasing PSD2 certificates or standing up your own bank integration. open-banking.io gives you a single, privacy-first path to Hüttenberger Bank (BIC GENODE51HUT) account data across the bank's business and personal products. You link the account once, and everything that follows — balances, transaction history, ongoing syncs — runs on a key that never leaves your device.

Hüttenberger Bank eG is a Hessen cooperative bank, and open-banking.io speaks its PSD2 dialect natively alongside 2,600+ other EU and UK institutions. The service is zero-knowledge and certificate-free: open-banking.io stores only your public key, so its servers physically cannot read or decrypt what they hold for you.

How to connect Hüttenberger Bank

Connecting happens entirely in 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 an encryption passphrase. Your key pair is generated locally on your own device from that passphrase.
2. In the dashboard, search for Hüttenberger Bank and choose the account type you want to link — business or personal.
3. You are redirected to Hüttenberger Bank's own secure login, where you approve access on the bank's PSD2 consent screen. That consent lasts up to 180 days before you renew it.
4. Your approved accounts sync back into your dashboard, ready to view.

Access your data

Once the account is linked, developers can optionally read it programmatically. 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. Every request carries your key in the X-Api-Key header, and each response is decrypted locally with your private key — the API key alone only ever returns ciphertext. There is no connect command; the tooling reads and syncs connections you already approved in the dashboard.

All of this runs for roughly EUR 3/month.

Do I need an eIDAS certificate for Hüttenberger Bank?

No. open-banking.io is certificate-free; you approve access directly on Hüttenberger Bank's consent screen.

Can open-banking.io see my Hüttenberger Bank transactions?

No. It holds only your public key, so data stays encrypted and is decrypted only on your device.

How often do I re-authorise?

Hüttenberger Bank grants consent for up to 180 days, after which you re-approve to keep syncing.
