Rønde Sparekasse API Access & Open Banking Data

Rønde Sparekasse is a local Danish savings bank serving retail and small-business customers around Rønde, and open-banking.io lets you reach its account and transaction data without touching a bank API, eIDAS certificate, or PSD2 sandbox of your own. open-banking.io is a zero-knowledge open-banking service covering 2,600+ EU and UK banks, where every byte your bank returns is decrypted locally with an encryption key that only you hold. Whether you hold a business or a personal account at Rønde Sparekasse, you get a single, private view of your finances.

How to connect Rønde Sparekasse

Connecting happens entirely inside the open-banking.io dashboard — there is no code, no endpoint, and no key involved in this step.

  1. Sign up for open-banking.io and set your encryption passphrase. Your keys are generated on your own device, so the platform never sees them.
  2. In the dashboard, search for Rønde Sparekasse and choose your account type (business or personal).
  3. You are redirected to Rønde Sparekasse's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Your accounts sync straight back into your dashboard. Consent lasts up to 180 days, after which you simply re-approve.

Because Rønde Sparekasse has no published BIC in the directory, open-banking.io matches it by name and country so you land on the correct institution.

Access your data

Want programmatic access? That is an optional developer step you take after connecting in the dashboard. On the Developers page, create an API key and export a credentials.json — which 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. Requests authenticate with 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.

Does open-banking.io see my Rønde Sparekasse data?

No. It is zero-knowledge and stores only your public key. Without your private key, an API key alone returns nothing but ciphertext.

Do I need a certificate or developer account with the bank?

No. open-banking.io is certificate-free; the licensed PSD2 access is handled for you.

What does it cost?

Around EUR 3/month for full access across every supported bank, including Rønde Sparekasse.
