iBanFirst API Access & Open Banking Data Sync

Reading your iBanFirst balances and transactions no longer means wrestling with PSD2 certificates or building a bank integration from scratch. open-banking.io gives you a single, encrypted view of your iBanFirst accounts (BIC FXBBBEBBXXX) — and, when you want it, a clean programmatic path to the same data. Both business and personal account types are supported, and a single consent stays valid for up to 180 days before you renew it.

The service is zero-knowledge and certificate-free: your data is decrypted locally with a key that only you hold. open-banking.io stores only your public key, so its servers can never read your iBanFirst statements.

How to connect iBanFirst

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 on your own device.
  2. In the dashboard, pick iBanFirst from the bank list and choose the account type you want (business or personal).
  3. You are redirected to iBanFirst's own secure login to approve access under PSD2 consent.
  4. Once you approve, your accounts sync back into your dashboard, ready to view.

That's the whole flow. You authenticate on iBanFirst's side, not on ours, so your credentials never touch open-banking.io.

Access your data

After iBanFirst is connected, developers can optionally read the data programmatically. On the Developers page, create an API key and export a credentials.json — this bundles your 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.

Every request sends the X-Api-Key header, and every response is decrypted locally with your own key. An API key alone only ever returns ciphertext — without your private key, the data stays unreadable. Note that the CLI and SDK only read and sync existing connections; there is no connect command, because connecting always happens in the dashboard.

All of this runs from about EUR 3/month, covering 2,600+ EU and UK banks.

FAQ

Do I need an eIDAS certificate for iBanFirst?

No. open-banking.io is certificate-free. You approve access directly on iBanFirst's consent screen and never handle PSD2 certificates.

Can open-banking.io read my iBanFirst data?

No. The service is zero-knowledge and holds only your public key. Decryption happens on your device with a private key only you control.

How long does an iBanFirst connection last?

Up to 180 days per consent. When it expires, simply re-approve access in the dashboard to keep your accounts syncing.
