PrimaCassa API Access & Open Banking Integration

Reaching PrimaCassa account data no longer means wrestling with certificates or bank-hosted developer portals. open-banking.io gives you a single, private route to your PrimaCassa balances and transactions across the EU and UK — covering more than 2,600 banks — while keeping decryption entirely on your own device. PrimaCassa, the Friuli Venezia Giulia cooperative bank identified by BIC CCRTIT2T99A, supports both business and personal accounts, and each authorisation stays valid for up to 180 days before you renew it.

Because the platform is zero-knowledge, open-banking.io only ever holds your public key. Every payload that flows back to you is ciphertext until it is unlocked locally with a private key that never leaves your machine.

How to connect PrimaCassa

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

  1. Sign up for open-banking.io and set your encryption passphrase. Your key pair is generated right there on your device.
  2. Open the dashboard, choose PrimaCassa from the bank list, and pick the account type you need — business or personal.
  3. You are redirected to PrimaCassa's own secure login, where you approve the PSD2 consent directly with the bank.
  4. Your accounts sync back into the dashboard, ready to view. The consent lasts up to 180 days.

Access your data

Programmatic access is an optional step for developers, and only after a PrimaCassa connection already exists. From 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 you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests carry the X-Api-Key header, and every response is decrypted locally with your own key. The CLI and SDK read and sync existing connections; they never connect a bank themselves.

All of this runs for roughly EUR 3/month, with no eIDAS certificates to buy or maintain.

Do I need an API key to connect PrimaCassa?

No. Connecting is done in the dashboard by approving consent on PrimaCassa's login screen. API keys only matter for later programmatic reads.

Can open-banking.io read my PrimaCassa data?

No. It stores only your public key. Data is decrypted locally, so the service cannot see your accounts.

What does the API key alone return?

Only ciphertext. Without your private decryption key from credentials.json, responses cannot be read.
