Banca della Valsassina Open Banking & API Access

Reaching your Banca della Valsassina accounts programmatically usually means wrestling with PSD2 certificates and sandbox paperwork. open-banking.io removes that friction. It is a zero-knowledge, certificate-free bridge to Banca della Valsassina (BIC ICRAITRREB0) and 2,600+ other EU and UK banks, where the data flowing back into your account is decrypted on your own device with a key that never leaves it.

Banca della Valsassina supports both business and personal account types through the service, and a single consent stays valid for up to 180 days before you need to re-approve — so you set access once and let it run for months.

How to connect Banca della Valsassina

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 device, so only you can later unlock the data.
  2. In the dashboard, search for Banca della Valsassina and choose the account type you want to link (business or personal).
  3. You are redirected to Banca della Valsassina's own secure login, where you approve the PSD2 access request directly with the bank.
  4. Once approved, your accounts and transactions sync back into your open-banking.io dashboard automatically.

That's the whole flow — you authenticate on the bank's screen, never by handing credentials to anyone else.

Access your data

Reading the data in code is an optional step you take after the connection exists. Open the Developers page, create an API key, and export a credentials.json — it 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. Every request carries your X-Api-Key header, and each response is decrypted locally with your own key. The API key alone only ever returns ciphertext — without your private key, nobody, including open-banking.io's servers, can read it. That's what zero-knowledge means here: the service holds only your public key.

All of this runs for roughly EUR 3/month, with no eIDAS certificate and no bank sandbox to register.

FAQ

No. Linking is done in the dashboard by approving access on Banca della Valsassina's login screen. API keys are only for optional programmatic reads afterward.

Can open-banking.io see my Banca della Valsassina transactions?

No. Data is decrypted on your device with a key only you hold; the servers store only your public key and encrypted payloads.

Up to 180 days per approval, after which you re-confirm access with the bank.
