Banco de Sabadell API Access & Open Banking Data

Banco de Sabadell (BIC BSABESBBXXX) is one of Spain's largest banking groups, and open-banking.io lets you reach its account data without wrestling with PSD2 certificates or eIDAS onboarding. You get a single, private dashboard for your Sabadell business or personal accounts, backed by a zero-knowledge design: your balances and transactions are decrypted locally with an encryption key that never leaves your device. open-banking.io's servers only ever hold your public key, so they cannot read what they store.

Whether you want a clean view of your finances or a programmatic feed for your own tooling, the path starts the same way — inside the dashboard.

How to connect Banco de Sabadell

Connecting happens entirely in the open-banking.io web 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 on your own device from that passphrase.
  2. In the dashboard, search for and select Banco de Sabadell, then choose the account type you hold — business or personal.
  3. You're redirected to Banco de Sabadell's own secure login, where you approve access on the bank's PSD2 consent screen. Your credentials go only to Sabadell, never to open-banking.io.
  4. Once approved, your accounts sync into your dashboard automatically. Each consent lasts up to 180 days, after which you simply re-approve on Sabadell's screen.

Access your data

After your Sabadell accounts are connected, developers can optionally read them 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 directly. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. Note that the API key alone only returns ciphertext — without your private key, nobody, including open-banking.io, can turn it into readable data. The CLI and SDK only read and sync connections you already made in the dashboard.

All of this runs for around EUR 3/month across 2,600+ EU/UK banks.

Does connecting Banco de Sabadell need an eIDAS certificate?

No. open-banking.io is certificate-free — you approve access on Sabadell's consent screen, nothing to install.

Can open-banking.io see my Sabadell transactions?

No. It's zero-knowledge: data is decrypted on your device with a key only you hold. Servers store ciphertext plus your public key.

What account types are supported?

Both business and personal Banco de Sabadell accounts, with consent valid for up to 180 days per approval.
