Caja Rural de Jaén Open Banking API Access | open-banking.io

Reaching your Caja Rural de Jaén accounts programmatically usually means chasing PSD2 certificates, sandbox registrations, and per-bank paperwork. open-banking.io removes all of that. As a member of the Banco Cooperativo Español network (BIC BCOEESMM067), Caja Rural de Jaén exposes standard PSD2 access — and open-banking.io wraps it in a single dashboard, whether you hold a business or personal account.

The difference is where your data lives. open-banking.io is zero-knowledge: your balances and transactions are decrypted only on your own device, with a key our servers never see. No eIDAS certificate, no bank-by-bank onboarding, no plaintext sitting on someone else's infrastructure.

How to connect Caja Rural de Jaén

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 locally, in your browser, from that passphrase.
  2. In the dashboard, search for Caja Rural de Jaén and choose your account type (business or personal).
  3. You are redirected to Caja Rural de Jaén's own secure login, where you approve access on the bank's consent screen — the standard PSD2 flow.
  4. Once approved, your accounts sync back into the dashboard. Consent lasts up to 180 days, after which you simply re-approve.

That's the whole flow: you authorise directly with the bank, and open-banking.io only ever stores data you've already encrypted.

Access your data

Want to read Caja Rural de Jaén data in your own code? That's an optional step, available after the connection above is live. On the Developers page, create an API key and export a credentials.json — it bundles your 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. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. Because our servers hold only your public key, an API key on its own returns ciphertext — readable data appears only once your private key decrypts it on your machine.

All of this is included for roughly EUR 3/month.

Do I need a PSD2 certificate for Caja Rural de Jaén?
