Tysnes Sparebank API Access & Open Banking

Reading your Tysnes Sparebank accounts through a single, privacy-first interface starts here. open-banking.io links to Tysnes Sparebank under PSD2, pulls your balances and transactions into one dashboard, and — because it is zero-knowledge and certificate-free — decrypts everything locally with a key that never leaves your device. No eIDAS certificate, no bank-specific integration work, and no servers that can read your statements.

Tysnes Sparebank supports both business and personal account types, and access consent lasts up to 180 days before you renew it. No BIC is required to get started — you simply pick the bank in the dashboard.

How to connect Tysnes Sparebank

Connecting happens entirely in 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 right there on your own device.
2. In the dashboard, choose Tysnes Sparebank and select whether you're linking a business or personal account.
3. You're redirected to Tysnes Sparebank's own secure login, where you approve access on the bank's PSD2 consent screen — your credentials are only ever entered at the bank.
4. Once approved, your accounts sync back into your dashboard, ready to view.

That's the whole flow. Because consent runs for 180 days, you'll re-approve on Tysnes Sparebank's screen roughly twice a year.

Access your data

Once a connection exists, developers can optionally read it programmatically. Open the Developers page, create an API key, and export a credentials.json — this bundles the API key with your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API directly. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. The API key alone only ever returns ciphertext — without your private key, the data stays unreadable, which is exactly how zero-knowledge is meant to work. The CLI and SDK only read and sync existing connections; they never create one.

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

Do I need an eIDAS certificate for Tysnes Sparebank?

No. open-banking.io is certificate-free — you approve access on the bank's consent screen and skip the certificate paperwork entirely.

Can open-banking.io read my Tysnes Sparebank transactions?

No. The service holds only your public key. Data is decrypted on your device, so the servers only ever store ciphertext.

Can I connect a business account?

Yes. Tysnes Sparebank supports both business and personal accounts; pick the type when you select the bank in the dashboard.
