Caja Rural de Extremadura Open Banking API Access

Reaching your Caja Rural de Extremadura balances and transactions no longer means wrestling with eIDAS certificates or bank-specific sandboxes. open-banking.io gives you PSD2-grade access to this Extremadura cooperative bank (BIC BCOEESMM009, part of the Banco Cooperativo Español network) through a single dashboard, covering both business and personal accounts. Everything is decrypted on your own device with a key only you hold, so the service is genuinely zero-knowledge and certificate-free.

How to connect Caja Rural de Extremadura

Connecting happens entirely in 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, so only your public key ever leaves your device.
  2. In the dashboard, search for Caja Rural de Extremadura and choose the account type you hold — business or personal.
  3. You are redirected to Caja Rural de Extremadura's own secure login, where you approve access on the bank's PSD2 consent screen. Consent lasts up to 180 days before it needs renewing.
  4. Your accounts sync straight back into the dashboard, ready to view.

That's the whole flow — you authenticate with the bank directly, and open-banking.io never sees your credentials.

Access your data

Once Caja Rural de Extremadura 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. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. An API key alone only ever returns ciphertext; without your private key, the data stays unreadable — including to open-banking.io itself.

All of this runs for around EUR 3/month, with access to 2,600+ EU/UK banks under one account.

Is a certificate or QWAC needed for Caja Rural de Extremadura?

No. open-banking.io handles the regulated PSD2 access for you, so you never register a certificate or manage a sandbox.

Can I connect a business and a personal account?

Yes. Caja Rural de Extremadura supports both account types — pick the relevant one when you add the bank in the dashboard, and repeat for the other.

Can open-banking.io read my transactions?

No. It stores only your public key and encrypted blobs. Decryption happens on your device with a private key that never leaves it.
