Sparkasse Bamberg API Access & Open Banking Data

Sparkasse Bamberg serves customers across Upper Franconia, and open-banking.io lets you reach its account data without wrangling PSD2 certificates or building your own bank integration. It works with both business and personal accounts (BIC BYLADEM1SKB), and everything you retrieve is decrypted on your own device with a key that never leaves it — open-banking.io only ever holds your public key, so the service itself can never read your statements.

The model is deliberately simple: one flat subscription of roughly EUR 3/month covers 2,600+ EU and UK banks, Sparkasse Bamberg included. No per-call fees, no eIDAS certificate, no bank-specific onboarding.

How to connect Sparkasse Bamberg

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 keys are generated locally on your device at this moment.
2. In the dashboard, search for Sparkasse Bamberg and choose the account type you want to link — business or personal.
3. You are redirected to Sparkasse Bamberg's own secure login, where you approve access directly on the bank's PSD2 consent screen. Your credentials are only ever entered at the bank.
4. Once approved, your accounts and transactions sync into your open-banking.io dashboard. Consent lasts up to 180 days, after which you simply re-approve on the bank's screen.

Access your data

Reading the data programmatically is an optional developer step, only after a 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.

With that file you can 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 private key. An API key on its own returns only ciphertext — without your key there is nothing readable to see. Note there is no connect command; the CLI and SDK only read and sync connections you already made in the dashboard.

Do I need a certificate for Sparkasse Bamberg?

No. open-banking.io is certificate-free — you never obtain or manage an eIDAS/PSD2 certificate yourself.

Can open-banking.io see my Sparkasse Bamberg transactions?

No. It is zero-knowledge and stores only your public key. Decryption happens on your device with a private key only you hold.

How long does access to Sparkasse Bamberg last?

Up to 180 days per consent. When it expires, re-approve on Sparkasse Bamberg's own login screen to continue syncing.
