Caixa Económica Montepio Geral Open Banking & API Access

Reading your Caixa Económica Montepio Geral balances and transactions no longer means wrestling with certificates or a bespoke bank integration. open-banking.io gives you PSD2 access to Caixa Económica Montepio Geral (BIC MPIOPTPLXXX) alongside 2,600+ European banks, covering both business and personal accounts, through one privacy-first workflow. Everything is decrypted locally with a key only you hold — the service never sees your data in the clear.

How to connect Caixa Económica Montepio Geral

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 your encryption passphrase. Your keys are generated on your own device, so only you can unlock what syncs back.
  2. In the dashboard, pick Caixa Económica Montepio Geral and choose the account type you hold — business or personal.
  3. You are redirected to Caixa Económica Montepio Geral's own secure login, where you approve access on the bank's PSD2 consent screen. Consent lasts up to 180 days before you renew it.
  4. Your accounts sync straight into your dashboard, ready to view.

Because the whole approval happens on Montepio's side, your login credentials are never shared with open-banking.io.

Access your data

Once Caixa Económica Montepio Geral 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 you can 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. Without that private key, an API key alone returns only ciphertext — which is exactly how zero-knowledge is meant to work.

At roughly EUR 3/month, you get certificate-free, zero-knowledge access where open-banking.io stores only your public key.

Do I need a developer certificate for Caixa Económica Montepio Geral?

No. open-banking.io is certificate-free — you approve access on Montepio's own consent screen and you're done.

Can open-banking.io read my Montepio transactions?

No. Data is decrypted on your device with a key only you hold; the servers keep only your public key and see ciphertext.

Up to 180 days, after which you simply re-approve access from the dashboard.
