Banca Monte dei Paschi di Siena API Access & Open Banking

Reaching your Banca Monte dei Paschi di Siena accounts programmatically usually means wrestling with eIDAS certificates and a bespoke PSD2 sandbox. open-banking.io removes that overhead. It is a certificate-free, zero-knowledge bridge covering 2,600+ EU and UK banks, so you can pull balances and transactions from the Sienese bank without registering as a licensed provider. Every response is decrypted on your own device with a key only you hold — open-banking.io servers only ever see your public key and ciphertext.

Banca Monte dei Paschi di Siena (BIC PASCITMMXXX) works for both business and personal accounts, and a single consent stays valid for up to 180 days before the bank asks you to re-authorise.

How to connect Banca Monte dei Paschi di Siena

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

  1. Sign up for open-banking.io and set an encryption passphrase. Your key pair is generated locally on your device from that passphrase.
  2. In the dashboard, search for Banca Monte dei Paschi di Siena and choose the account type you need — business or personal.
  3. You are redirected to Monte dei Paschi's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Once approved, your accounts sync back into the dashboard, ready to view and refresh.

Because you authorise directly on the bank's site, your credentials are never shared with open-banking.io.

Access your data

Programmatic access is an optional step for developers, taken only after a connection exists. Open the Developers page, create an API key, and download a credentials.json — it bundles the API key with your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests carry the X-Api-Key header, and each response is decrypted locally with your private key. An API key on its own only returns ciphertext — without your key there is nothing readable to leak. Note the CLI and SDKs read and sync existing connections; they cannot connect a bank.

All of this runs for around EUR 3/month, with no certificate paperwork and no third-party ever holding your plaintext.
