Renta 4 Banco API Access & Open Banking Data

Renta 4 Banco (BIC RENBESMMXXX) is a Spanish institution best known for investment and brokerage services. If you want your Renta 4 Banco balances and transactions in one place — a spreadsheet, a reconciliation script, or a personal dashboard — open-banking.io gives you PSD2 access without certificates, sandboxes, or bank-by-bank paperwork. It covers 2,600+ EU and UK banks, and every figure is decrypted on your own device with a key that never leaves it.

Both business and personal Renta 4 Banco accounts are supported, and a single approval keeps data flowing for up to 180 days before you renew.

How to connect Renta 4 Banco

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 keys are generated locally on your device, so open-banking.io only ever holds your public key.
  2. In the dashboard, search for Renta 4 Banco and choose the account type you hold — business or personal.
  3. You are redirected to Renta 4 Banco's own secure login, where you review and approve the access request (standard PSD2 consent).
  4. Once approved, your accounts sync back into the dashboard, ready to view.

That consent lasts up to 180 days; you simply re-approve on Renta 4 Banco's screen when it expires.

Access your data

Reading Renta 4 Banco data programmatically is an optional step that comes after the connection exists. On the Developers page, create an API key and export a credentials.json — this bundles the API key with your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API directly. Calls authenticate with the X-Api-Key header, and each response is decrypted locally with your own key. The CLI and SDK only read and sync connections you already made in the dashboard — there is no connect command.

At around EUR 3/month, that is the whole cost.

FAQ

Do I connect Renta 4 Banco with an API key?

No. You connect in the dashboard and approve on Renta 4 Banco's login page. API keys only come later, if you want to read the data with code.

Can open-banking.io see my Renta 4 Banco data?

No. The service is zero-knowledge and holds only your public key. Data is decrypted on your device with a private key that only you have.

What if I only have an API key, not my private key?

You would receive ciphertext. Readable results require your own private decryption key, which is why credentials.json includes both.
