Access Banco Di Sardegna Data via Open Banking API

Banco Di Sardegna serves households and companies across Sardinia and beyond, and with open-banking.io you can reach your account data without wrestling with bank APIs, eIDAS certificates, or PSD2 licensing. open-banking.io is a certificate-free bridge to 2,600+ European banks that keeps you in control: your data is encrypted and only ever decrypted on your own device, with a key that never leaves your hands.

Whether you hold a business or personal account (both are supported, BIC SARDIT31XXX), the flow is the same and takes minutes.

How to connect Banco Di Sardegna

Connecting happens entirely inside the open-banking.io dashboard — there is no code, no endpoint call, and no API key at this stage.

  1. Sign up for open-banking.io and set your encryption passphrase. Your cryptographic keys are generated locally on your device, so nobody else — not even open-banking.io — can read what comes next.
  2. In the dashboard, search for Banco Di Sardegna and choose your account type (business or personal).
  3. You are redirected to Banco Di Sardegna's own secure login, where you approve access under PSD2. Consent lasts up to 180 days before you renew it.
  4. Your accounts and transactions sync straight into your dashboard.

That's the whole connection. No developer redirects the account holder anywhere — you approve directly on the bank's screen.

Access your data

Once Banco Di Sardegna is connected, developers can optionally read the data programmatically. Open the Developers page, create an API key, and export a credentials.json — this bundles your 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 every response is decrypted locally with your own key. An API key alone only ever returns ciphertext — without your private key the data stays unreadable, which is what "zero-knowledge" really means. The CLI and SDK only read and sync connections you already made in the dashboard; there is no connect command.

All of this runs for around EUR 3/month.

Does open-banking.io store my banking password?

No. You authenticate on Banco Di Sardegna's own login, and open-banking.io holds only your public key — never your credentials or readable data.

Can I use both business and personal accounts?

Yes. Banco Di Sardegna supports both account types; pick the one you want when connecting, or add each separately.

How long does access last?

Each consent is valid for up to 180 days, after which you simply re-approve from the dashboard.
