Caja Rural de Salamanca API Access & Open Banking

Reading your Caja Rural de Salamanca balances and transactions no longer means wrangling PSD2 certificates or standing up your own TPP infrastructure. open-banking.io gives you certificate-free, read-only access to this Salamanca cooperative bank (BIC BCOEESMM016, part of the Banco Cooperativo Español network) across both business and personal accounts — and it does so with a zero-knowledge design, so only you can ever read the data that comes back.

How to connect Caja Rural de Salamanca

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 open-banking.io account.
  2. Set your encryption passphrase. Your keys are generated locally on your own device; the service only ever holds your public key.
  3. In the dashboard, pick Caja Rural de Salamanca and choose the account type — business or personal.
  4. You're redirected to Caja Rural de Salamanca's own secure login, where you approve access on the bank's PSD2 consent screen.
  5. Your accounts sync straight into your dashboard.

Consent lasts up to 180 days, after which you simply re-approve on the bank's screen to keep the connection live.

Access your data

Once the bank is connected, reading it programmatically is an optional developer step. Head to 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 you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API directly.

Every request carries your key in the X-Api-Key header, and every response is decrypted locally with your private key. The API key on its own only ever returns ciphertext — without the private key held on your device, nobody, including open-banking.io's servers, can turn it into readable account data.

All of this runs for around EUR 3/month, with no certificate paperwork and no per-connection setup fees.

Is my Caja Rural de Salamanca data readable by open-banking.io?

No. The platform is zero-knowledge and stores only your public key. Decryption happens on your device with a private key that never leaves it.

Do I need an API key to connect the bank?

No. Connecting is done entirely in the dashboard via Caja Rural de Salamanca's own consent screen. API keys and credentials.json are only for reading data afterward.

Can I access business and personal accounts?

Yes. Both account types are supported, each connected separately by choosing the account type in the dashboard.
