Caixalmassora API Access & Open Banking | open-banking.io

Caixalmassora (Caixa Rural d'Almassora) serves the Castellón region as part of the Grupo Caja Rural cooperative network, operating under BIC BCOEESMM130. If you want your Caixalmassora balances and transactions in one place — or feeding a script — open-banking.io gives you PSD2 access without eIDAS certificates, without a bank sponsorship, and without handing anyone else the keys to your data.

The service reaches 2,600+ European banks. What makes it different is the trust model: your data is decrypted locally, with a key that only ever exists on your device. open-banking.io's servers hold your public key and nothing more, so they physically cannot read your account information.

How to connect Caixalmassora

Connecting happens entirely inside the open-banking.io dashboard — there's no API call, code, or key involved in this step:

  1. Sign up for open-banking.io and set your encryption passphrase. Your key pair is generated right there on your own device.
  2. In the dashboard, search for Caixalmassora and choose the account type you hold — business or personal.
  3. You're redirected to Caixalmassora's own secure login, where you approve access on the bank's official PSD2 consent screen.
  4. Once approved, your accounts sync back into your dashboard. Consent lasts up to 180 days, after which you simply reauthorise.

That's the whole flow — you authenticate directly with your bank, never through a third party pretending to be you.

Access your data

Want Caixalmassora data in your own tools? This is an optional developer step, available only after you've connected in the dashboard. On the Developers page, create an API key and export a credentials.json — it bundles the API key together with your private decryption key. From there:

openbanking accounts
openbanking transactions
openbanking sync

The CLI, SDKs, and REST API all authenticate with the X-Api-Key header, and every response is decrypted locally with your private key. An API key on its own only ever returns ciphertext — without your key, there's nothing readable to see. The command-line tools read and sync existing connections; the bank link itself is always made in the dashboard.

All of this runs for roughly EUR 3/month.

Is a bank certificate required?

No. open-banking.io is certificate-free — no eIDAS QWAC or sponsoring bank needed to reach Caixalmassora.

Can open-banking.io read my Caixalmassora transactions?

No. The architecture is zero-knowledge. Servers store only your public key, and decryption happens on your device.

Which account types are supported?

Both business and personal Caixalmassora accounts, under BIC BCOEESMM130, with consent valid for up to 180 days.
