Access Numia (Italy) Data — API & Open Banking

Numia serves personal and business customers across Italy, and open-banking.io lets you reach that account data without wrestling with eIDAS certificates, sandbox registrations or PSD2 licensing. Everything runs through the open-banking.io dashboard, and every figure that lands in front of you is decrypted on your own device with a key that never leaves it. Numia operates under BIC ICRAITRRXXX, and a single consent stays valid for up to 180 days before you renew it.

How to connect Numia

Connecting is a dashboard task, not a coding task. First, create an open-banking.io account and set an encryption passphrase — this generates your personal key pair locally, so only you can ever unlock the data. Next, open the dashboard, search for Numia and choose whether you are linking a personal or business account. open-banking.io then redirects you to Numia's own secure login, where you authenticate and approve the access request on the bank's PSD2 consent screen. Once Numia confirms, your accounts and transactions flow back into your dashboard and stay in sync. No API key, endpoint call or developer redirect is involved in this step — you approve access directly with your bank.

Access your data

If you want Numia data in your own code, that comes after the connection exists. Head to the Developers page, generate an API key and download a credentials.json file — it bundles that API key together with your private decryption key. From there you can run the CLI (openbanking accounts, openbanking transactions, openbanking sync), call the REST API, or use an SDK. Requests authenticate with the X-Api-Key header, and each response is decrypted locally against your key. Because open-banking.io is zero-knowledge and holds only your public key, an API key on its own returns nothing but ciphertext — readable data requires the private key that stays with you.

FAQ

Do I need a PSD2 certificate to access Numia?

No. open-banking.io is certificate-free. You approve access on Numia's login screen and skip the eIDAS and licensing overhead entirely.

Can I connect Numia with the CLI or an API call?

No. Connecting always happens in the dashboard via Numia's consent flow. The CLI, SDK and API only read or sync connections that already exist.

Around EUR 3 per month, covering both personal and business Numia accounts. Each PSD2 consent remains active for up to 180 days before renewal.
