Isybank Open Banking & API Access | open-banking.io

Isybank is the digital bank of the Intesa Sanpaolo group, serving customers across Italy. If you want a clean, programmatic view of your Isybank money — balances, transactions, and history — open-banking.io gives you PSD2 access without the certificate paperwork or the eIDAS onboarding that usually stands between a developer and their own bank data.

open-banking.io is a zero-knowledge service covering more than 2,600 banks in the EU and UK. Your Isybank data is encrypted the moment it arrives and decrypted only on your device, using a key that never leaves your hands. The service holds your public key alone, so its servers can never read what flows through them.

How to connect Isybank

Connecting happens entirely inside the open-banking.io dashboard — there is no API call, code, or key involved in linking the account:

  1. Sign up for open-banking.io and set an encryption passphrase. Your cryptographic keys are generated locally on your own device at this step.
  2. In the dashboard, choose Isybank (BIC ISYBITMMXXX) and select your account type — both business and personal accounts are supported.
  3. You are redirected to Isybank's own secure login, where you approve the PSD2 consent directly with the bank. open-banking.io never sees your banking credentials.
  4. Once approved, your accounts sync back into the dashboard and stay refreshed for the life of the consent — up to 180 days, after which you simply re-authorise.

Access your data

Programmatic access is an optional step you take after the bank is connected. From the Developers page, create an API key and export a credentials.json file, which bundles that API key together with your private decryption key. From there you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API directly.

Every request carries your key in the X-Api-Key header, and every response is decrypted locally with your private key. An API key on its own only ever returns ciphertext — without your key, there is nothing readable to see. There is no connect command: the CLI and SDK read and sync existing connections, never create them.

All of this runs for roughly EUR 3/month, with no certificate fees.
