Revolut Spain API Access & Open Banking Data | open-banking.io

Revolut has become one of Spain's go-to accounts for everyday spending, multi-currency balances and business cash flow. If you want your Revolut (Spain) transactions and balances in one place — or flowing into your own scripts — open-banking.io gives you read access without certificates, eIDAS setup or a PSD2 licence of your own. It covers both Revolut business and personal accounts (BIC REVOLT21), and a single consent stays valid for up to 180 days before you re-approve.

The whole thing is zero-knowledge: your data is decrypted on your own device with a key only you hold. open-banking.io's servers keep only your public key, so they can never read your balances or transactions.

How to connect Revolut

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

  1. Sign up at open-banking.io and set your encryption passphrase. Your encryption keys are generated locally on your device at this moment.
  2. In the dashboard, pick Revolut (Spain) from the bank list and choose the account type — business or personal.
  3. You're redirected to Revolut's own secure login, where you approve the access request (standard PSD2 consent) directly with the bank.
  4. Once approved, your Revolut accounts sync back into your dashboard and refresh automatically.

You never hand your Revolut credentials to open-banking.io — approval always happens on Revolut's side.

Access your data

Reading data programmatically is an optional developer step after your Revolut connection is live. 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. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. The API key alone only ever returns ciphertext — without your private key, no one (not even open-banking.io) can read it. The CLI and SDK only read and sync connections you've already made in the dashboard.

All of this runs for around EUR 3/month.

Does connecting Revolut need a certificate or licence?

No. There's no eIDAS certificate or PSD2 licence to obtain — you approve access on Revolut's login and open-banking.io handles the rest.

Can open-banking.io see my Revolut transactions?

No. It's zero-knowledge and holds only your public key. Data is decrypted on your device with a key only you have.

How long does my access last?

Up to 180 days per consent. After that, you re-approve on Revolut's screen to keep syncing.
