Kreissparkasse Tuttlingen Open Banking API Access
Reaching your Kreissparkasse Tuttlingen accounts programmatically no longer means chasing PSD2 certificates or standing up your own compliance stack. With open-banking.io you link the bank once through a guided web dashboard, and your balances and transactions become available to read — in your app, a script, or a spreadsheet — while staying encrypted end to end. The service covers 2,600+ EU and UK banks, so Kreissparkasse Tuttlingen (BIC SOLADES1TUT) sits alongside every other account you hold.
Both business and personal account types are supported, and a single approval grants access for up to 180 days before you renew.
How to connect Kreissparkasse Tuttlingen
Connecting happens entirely inside the open-banking.io dashboard — there is no API call, code, or key involved in this step.
- Sign up for open-banking.io and set your encryption passphrase. Your keys are generated locally on your own device, so only you ever hold them.
- In the dashboard, search for Kreissparkasse Tuttlingen and choose the account type — business or personal.
- You are redirected to Kreissparkasse Tuttlingen's own secure login, where you approve access on the bank's official PSD2 consent screen.
- Once approved, your accounts sync back into the dashboard and refresh automatically for the life of the consent.
Because you authenticate directly with the bank, open-banking.io never sees your login credentials.
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 use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. The CLI and SDK only read and sync connections you already made in the dashboard — they cannot create one.
This is what zero-knowledge means in practice: open-banking.io stores only your public key, so its servers hold ciphertext they cannot read. No eIDAS certificate, no bank onboarding paperwork — just about EUR 3/month.
Is my Kreissparkasse Tuttlingen login shared with open-banking.io?
No. You enter it only on the bank's own consent page. open-banking.io never receives it.
Does an API key alone return readable data?
No. Without your private decryption key an API response is only ciphertext — the key never leaves your device.
How long does access last?
Up to 180 days per consent, after which you re-approve on Kreissparkasse Tuttlingen's screen.
