iBanFirst Open Banking & API Access | open-banking.io

Reaching your iBanFirst balances and payment history outside the bank's own portal usually means wrestling with certificates and PSD2 red tape. open-banking.io removes that friction: it links to iBanFirst on your behalf and streams the data into one encrypted dashboard, covering both business and personal accounts. Because keys are generated on your device, only you can ever read what comes back.

How to connect iBanFirst

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

  1. Sign up at open-banking.io and set an encryption passphrase. Your decryption keys are created locally, so the service only ever holds your public key.
  2. In the dashboard, search for iBanFirst (BIC FXBBBEBBXXX) and choose the account type you hold — business or personal.
  3. You're redirected to iBanFirst's own secure login, where you approve access on their PSD2 consent screen. Your credentials are entered only on the bank's site.
  4. Your accounts sync straight into your dashboard. A single approval stays valid for up to 180 days, after which you simply re-confirm.

Access your data

Once iBanFirst is linked, reading it programmatically is an optional developer step. Open 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 the CLI (openbanking accounts, openbanking transactions, openbanking sync), the SDKs, or the REST API all work. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. The API key on its own only ever returns ciphertext — without your private key there is nothing readable to leak.

The whole service is certificate-free and zero-knowledge, running at roughly EUR 3/month, with no eIDAS setup or bank-by-bank paperwork.

Do I connect iBanFirst with an API key?

No. You link iBanFirst in the dashboard and approve on the bank's consent screen. API keys only read data you've already connected.

Can open-banking.io staff see my iBanFirst transactions?

No. They store only your public key. Data is decrypted on your device, so servers hold ciphertext they cannot open.

iBanFirst grants access for up to 180 days per approval; renew from the dashboard when it lapses.
