Sønderhå-Hørsted Sparekasse API & Open Banking Access

Reaching your Sønderhå-Hørsted Sparekasse accounts programmatically usually means chasing PSD2 certificates and bank sandboxes. open-banking.io removes that friction: it links your Sønderhå-Hørsted Sparekasse balances and transactions to one dashboard, and — because it is zero-knowledge — every figure is decrypted on your own device with a key only you hold. No eIDAS certificate, no onboarding paperwork.

Whether you run a company account or a private one, Sønderhå-Hørsted Sparekasse works the same way here: both business and personal account types are supported, and a single consent stays valid for up to 180 days before you re-approve. Sønderhå-Hørsted Sparekasse does not publish a BIC through this channel, so none is required to connect.

How to connect Sønderhå-Hørsted Sparekasse

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

  1. Sign up for open-banking.io and set your encryption passphrase. Your keys are generated locally on your device, so open-banking.io only ever stores your public key.
  2. In the dashboard, pick Sønderhå-Hørsted Sparekasse and choose the account type (business or personal).
  3. You are redirected to Sønderhå-Hørsted Sparekasse's own secure login to approve access (the standard PSD2 consent screen). open-banking.io never sees your credentials.
  4. Once you confirm, your accounts sync back into the dashboard automatically.

Access your data

After the connection exists, reading it in code is an optional developer step. Open the Developers page, create an API key, and export a credentials.json — this bundles the API key and your private decryption key. Then use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests authenticate with the X-Api-Key header, and each response is decrypted locally with your key. The CLI and SDK only read or refresh connections you already approved — they never establish new ones. An API key on its own returns ciphertext; without your private key it stays unreadable, even to open-banking.io.

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

Do I need a certificate for Sønderhå-Hørsted Sparekasse?

No. open-banking.io is certificate-free — you approve access directly on Sønderhå-Hørsted Sparekasse's consent screen.

Can open-banking.io read my Sønderhå-Hørsted Sparekasse data?

No. It holds only your public key. Decryption happens on your device, so the servers see ciphertext.
