Access iBanFirst Data — Open Banking & API Access

Want a clean, private route to your iBanFirst balances and transactions? open-banking.io links your iBanFirst accounts through regulated PSD2 access and hands the data back to you already decrypted on your own device. It covers 2,600+ EU and UK banks, needs no eIDAS certificate, and works for both business and personal iBanFirst accounts (BIC FXBBBEBBXXX).

The difference is where the trust sits. open-banking.io is zero-knowledge: your encryption keys are generated locally and the service only ever holds your public key, so it stores ciphertext it cannot read. Nobody but you can turn your iBanFirst data back into plain text.

How to connect iBanFirst

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

  1. Sign up for open-banking.io and set your encryption passphrase. Your keys are created on your device at this moment.
  2. In the dashboard, choose iBanFirst and pick the account type you hold — business or personal.
  3. You are redirected to iBanFirst's own secure login to approve access under PSD2. You authenticate directly with the bank; open-banking.io never sees your credentials.
  4. Once you confirm, your iBanFirst accounts sync into the dashboard. The consent stays valid for up to 180 days, after which you simply re-approve on iBanFirst's screen.

Access your data

Reading iBanFirst data programmatically is an optional developer step, only after the account is connected. 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. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. The API key alone only returns ciphertext — without your private key, there is nothing readable to see. Note there is no connect command; the CLI and SDK read and sync existing connections, never create them.

All of this runs for roughly EUR 3/month.

Do I need an eIDAS certificate for iBanFirst?

No. open-banking.io is certificate-free — you connect through the dashboard and approve on iBanFirst's own login.

Can open-banking.io read my iBanFirst transactions?

No. It holds only your public key and stores encrypted data; decryption happens on your device.

How long does iBanFirst access last?

Up to 180 days per consent, then you re-approve directly with iBanFirst.
