CRA Castellana Grotte API Access & Open Banking

Reach your CRA Castellana Grotte accounts through a single, privacy-first dashboard. open-banking.io is a certificate-free EU/UK open-banking service covering 2,600+ banks, so you can view balances and transactions from your Cassa Rurale ed Artigiana di Castellana Grotte accounts without wrestling with eIDAS certificates or bank-specific paperwork. Everything you pull is encrypted for you and decrypted locally with a key that never leaves your device — our servers only ever hold your public key.

CRA Castellana Grotte supports both personal and business accounts, and open banking consent lasts up to 180 days before you re-approve. No BIC is required to get started.

How to connect CRA Castellana Grotte

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

  1. Sign up at open-banking.io and set your encryption passphrase. Your keys are generated right on your own device.
  2. In the dashboard, search for and select CRA Castellana Grotte, then choose the account type (personal or business).
  3. You are redirected to CRA Castellana Grotte's own secure login and consent screen, where you approve access under PSD2 — directly with the bank.
  4. Your accounts then sync back into your dashboard, ready to view.

That's the whole flow: approve once with your bank, and your data appears in your dashboard.

Access your data

Once CRA Castellana Grotte is connected, developers can optionally read the data programmatically. On the Developers page, create an API key and export a credentials.json — this 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. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. The CLI and SDK only read and sync connections you already made in the dashboard — there is no connect command. Without your private key, an API key alone returns only ciphertext.

All of this runs for around EUR 3/month.

Do I need an eIDAS certificate for CRA Castellana Grotte?
