Findomestic API Access & Open Banking Integration

Findomestic customers in Italy can bring their account data into a single, privacy-first workspace with open-banking.io. Whether you want to review balances, categorise spending, or feed transactions into your own tooling, open-banking.io gives you PSD2 access to Findomestic (BIC FIDMIT31XXX) without certificates, sandboxes, or paperwork. Both business and personal accounts are supported, and each authorisation lasts up to 180 days before you re-confirm.

The defining trait is zero-knowledge encryption: your financial data is decrypted locally, on your own device, with a key that only you hold. open-banking.io's servers store your public key and ciphertext — never anything they can read.

How to connect Findomestic

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

  1. Sign up for open-banking.io and set your encryption passphrase. Your keys are generated on your device at this step.
  2. In the dashboard, choose Findomestic and select the account type (business or personal).
  3. You are redirected to Findomestic's own secure login, where you approve access under PSD2 — your credentials go only to the bank.
  4. Once you consent, your Findomestic accounts sync back into your dashboard, ready to view.

That consent stays valid for up to 180 days, after which a quick re-approval keeps the connection live.

Access your data

Reading data programmatically is an optional developer step you take after the bank is connected. On the Developers page, create an API key and export a credentials.json — it 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. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. Without that private key, an API key alone returns only ciphertext — which is exactly the point.

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

Do I need a developer account to use Findomestic?

No. Linking Findomestic and viewing accounts is done in the dashboard. API keys and the CLI are only for developers who later want programmatic reads.

Can open-banking.io see my Findomestic balance?

No. Data is decrypted on your device with a key only you hold. The service stores just your public key and encrypted data.

Up to 180 days per authorisation, then you re-approve on Findomestic's login screen to continue syncing.
