Globalcaja API Access & Open Banking Data | open-banking.io

Globalcaja, the Castilla-La Mancha rural bank, exposes account data under PSD2 — and open-banking.io turns that regulatory access into something you can actually use in minutes. Instead of eIDAS certificates, sandbox registrations, or bank-by-bank paperwork, you get one dashboard that reaches Globalcaja alongside 2,600+ other EU and UK institutions. Balances and transactions land in your account already encrypted, and only you hold the key to read them.

Globalcaja (BIC BCOEESMM190) supports both business and personal accounts, with access consent lasting up to 180 days before Globalcaja asks you to re-authorise.

How to connect Globalcaja

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

  1. Sign up for open-banking.io and open the web dashboard.
  2. Set your encryption passphrase. Your key pair is generated on your own device; open-banking.io only ever sees your public key.
  3. Pick Globalcaja from the bank list and choose the account type — business or personal.
  4. Approve on Globalcaja's own login. You're redirected to the bank's secure consent screen, where you authenticate directly and grant access.
  5. Watch your accounts sync back into the dashboard, ready to view.

That's the whole flow. Your credentials are only ever entered on Globalcaja's side.

Access your data

Reading the data programmatically is an optional step after the connection exists. From the Developers page, create an API key and export a credentials.json — it bundles the API key with your private decryption key. Then 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. An API key on its own returns only ciphertext — the private key never leaves your machine, so open-banking.io's servers can't read a thing.

All of this runs at roughly EUR 3/month, with no certificate costs.

Do I need an eIDAS certificate for Globalcaja?

No. open-banking.io handles the regulated PSD2 layer, so you connect Globalcaja without any certificate of your own.

Can open-banking.io see my Globalcaja transactions?

No. The service is zero-knowledge — it stores only your public key, and your data is decrypted on your device with a private key only you hold.

Does the CLI connect my Globalcaja account?

No. The CLI and SDKs only read and sync connections you've already approved in the dashboard. There is no connect command; authorisation always happens on Globalcaja's login page.
