Sparkasse Hildesheim Goslar Peine API & Open Banking

Sparkasse Hildesheim Goslar Peine serves customers across Lower Saxony, and open-banking.io lets you reach both your business and personal accounts there without EIDAS certificates or a bespoke bank integration. The platform covers 2,600+ EU and UK banks, and everything you retrieve is decrypted on your own device with a key that never leaves it — the service itself only ever holds your public key.

Whether you are reconciling company ledgers or tracking a household budget, the same flow applies. You connect once in the dashboard, and from there your Sparkasse Hildesheim Goslar Peine balances and transactions stay in sync.

How to connect Sparkasse Hildesheim Goslar Peine

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 own device.
  2. In the dashboard, search for Sparkasse Hildesheim Goslar Peine (BIC NOLADE21HIK) and choose the account type you need — business or personal.
  3. You are redirected to Sparkasse Hildesheim Goslar Peine's own secure login, where you approve access under PSD2. Your credentials are only ever entered on the bank's screen.
  4. Once approved, your accounts sync into your dashboard. The consent lasts up to 180 days, after which you simply re-approve on the bank's screen.

Access your data

Reading your data programmatically is an optional developer step that comes after connecting. On 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 in place, the CLI works out of the box:

openbanking accounts
openbanking transactions
openbanking sync

You can also use an SDK or the REST API directly. 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 to see. That is what makes the system genuinely zero-knowledge.

Pricing is around EUR 3/month, with no per-certificate fees.

Does open-banking.io ever see my Sparkasse Hildesheim Goslar Peine data?

No. It stores only your public key. Decryption happens on your device, so the servers hold ciphertext they cannot read.

Can I connect a business and a personal account?

Yes. Both account types are supported — pick the relevant one when adding the bank in the dashboard.

How long does access stay active?

Up to 180 days per consent. When it expires, re-approve on Sparkasse Hildesheim Goslar Peine's own login screen.
