Cajamar Caja Rural API Access & Open Banking

Cajamar Caja Rural, Spain's largest cooperative credit institution, keeps rich account and transaction detail behind its own online banking. open-banking.io lets you reach that data without registering as a licensed provider or wrestling with eIDAS certificates. It sits on the regulated PSD2 rails (BIC CCRIES2AXXX) and covers both business and personal account types, so sole traders, cooperatives, and households can all pull a live view of their finances into one dashboard.

What sets it apart is the trust model. Your data is encrypted with keys generated on your own device and decrypted only there. open-banking.io stores just your public key, meaning its servers can never read your balances or statements — it is genuinely zero-knowledge, and there are no certificates to buy or renew. All of this runs for roughly EUR 3/month across 2,600+ European banks.

How to connect Cajamar Caja Rural

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 an account and set your encryption passphrase; your private keys are created locally on your device.
  2. In the dashboard, search for and select Cajamar Caja Rural, then choose the business or personal account type you want to link.
  3. You are redirected to Cajamar Caja Rural's own secure login, where you approve access on the bank's PSD2 consent screen. Consent can last up to 180 days before you re-authorise.
  4. Your accounts sync back into the dashboard and refresh automatically.

Access your data

Once Cajamar Caja Rural 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.

Do I need an eIDAS certificate?

No. open-banking.io is certificate-free; you approve access directly on Cajamar Caja Rural's login screen.

Can open-banking.io see my Cajamar Caja Rural data?

No. The service holds only your public key, so balances and transactions are readable solely on your device.

Up to 180 days, after which you re-approve access with Cajamar Caja Rural to keep syncing.
