Kreissparkasse Hildburghausen Open Banking API

Kreissparkasse Hildburghausen serves southern Thuringia with everyday business and personal banking, but its online portal was never built to hand your balances and transactions to the tools you actually use. open-banking.io closes that gap. It gives you a single, private view of your Kreissparkasse Hildburghausen accounts (BIC HELADEF1HIL) under PSD2, and — because it is zero-knowledge and certificate-free — your financial data is decrypted only on your own device, using a key that never leaves it.

That means no eIDAS certificate to buy, no bank-specific paperwork, and no third party quietly reading your statements. open-banking.io's servers hold only your public key; the ciphertext they store is meaningless without the private key you control.

How to connect Kreissparkasse Hildburghausen

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

  1. Sign up at open-banking.io and set an encryption passphrase. Your key pair is generated locally on your device from that passphrase.
  2. In the dashboard, search for and select Kreissparkasse Hildburghausen, then choose whether you are linking a business or personal account.
  3. You are redirected to Kreissparkasse Hildburghausen's own secure login, where you approve access on the bank's official PSD2 consent screen.
  4. Once approved, your accounts sync back into your 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 you take after connecting. 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. An API key on its own only ever returns ciphertext — without your private key there is nothing readable, which is exactly what zero-knowledge guarantees.

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

Do I need a developer account to use open-banking.io?

No. Connecting Kreissparkasse Hildburghausen and viewing accounts is done in the dashboard. API keys and the CLI are only for those who want programmatic access.

Can open-banking.io read my Kreissparkasse Hildburghausen data?

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

Up to 180 days per PSD2. When it expires, re-approve access on Kreissparkasse Hildburghausen's own consent screen.
