NEXI API Access & Open Banking Data (Italy)

Reaching your NEXI account data no longer means wrestling with eIDAS certificates or a bespoke bank integration. open-banking.io gives you a single, certificate-free path to NEXI (Italy) under PSD2, covering both business and personal accounts. Because the platform is zero-knowledge, every figure that lands in front of you is decrypted on your own device with a key nobody else holds — not even our servers, which only ever see your public key and ciphertext.

NEXI is identified by BIC NEPYITMM, and a single authorisation lets you keep reading balances and transactions for up to 180 days before you re-approve. That consent window applies equally to business and personal accounts.

How to connect NEXI

Connecting happens entirely inside the open-banking.io dashboard — there is no endpoint to call and no key to paste:

  1. Create your open-banking.io account and choose an encryption passphrase. Your cryptographic keys are generated locally, on your device, at this moment.
  2. Open the dashboard and search for NEXI (Italy), then pick the account type you hold — business or personal.
  3. You're redirected to NEXI's own secure login, where you approve access directly with the bank (standard PSD2 consent). Your credentials are only ever entered on NEXI's page.
  4. Once approved, your accounts sync back into the dashboard and stay refreshed for the length of your 180-day consent.

Access your data

Want your NEXI data in code? That's an optional step that comes after the connection above exists. On the Developers page, mint an API key and export a credentials.json — it bundles the API key with your private decryption key. From there the CLI (openbanking accounts, openbanking transactions, openbanking sync), the SDKs and the REST API all work the same way: requests carry an X-Api-Key header, and each response is decrypted locally with your own key. The API key alone only ever returns ciphertext, so a leaked key can't expose your finances. Note the CLI and SDKs read and sync existing connections — they never create one.

All of this runs at roughly EUR 3/month, with no certificate purchase, no vetting, and no per-call surprises.

FAQ

Do I need a PSD2 certificate to access NEXI?

No. open-banking.io is certificate-free — you authorise directly on NEXI's login screen and we handle the regulated plumbing.

Can open-banking.io read my NEXI transactions?

No. The service is zero-knowledge; data is decrypted only on your device with a key we never receive.

Can I connect NEXI from the CLI or SDK?

No. Connecting is done in the dashboard. The CLI, SDK and API only read or sync connections that already exist.
