iBanFirst API Access & Open Banking Data Sync

Cross-border payments and multi-currency accounts make iBanFirst a hub for finance and treasury teams — and open-banking.io lets you pull that account and transaction data into one place without wrestling with PSD2 certificates or eIDAS onboarding. It is a zero-knowledge, certificate-free service covering 2,600+ EU and UK banks, so iBanFirst is one dashboard selection away. Your data is encrypted and decrypted on your own device with a key that never leaves it; open-banking.io stores only your public key and can never read your balances.

How to connect iBanFirst

Connecting happens entirely inside 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 key pair is generated locally on your device.
  2. In the dashboard, pick iBanFirst (BIC FXBBBEBBXXX) and choose the account type you hold — business or personal.
  3. You are redirected to iBanFirst's own secure login to approve access under PSD2.
  4. Once you consent, your accounts sync back into the dashboard. Consent lasts up to 180 days, after which you simply re-approve on iBanFirst's screen.

Because you authorise directly with iBanFirst, open-banking.io never sees your banking credentials.

Access your data

Programmatic access is an optional step you take after the connection exists. 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 you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API directly.

Every request carries the X-Api-Key header, and every response is decrypted locally with your own key. An API key on its own only ever returns ciphertext — without your private key the data stays unreadable, which is what keeps the model genuinely zero-knowledge. The CLI and SDK read and refresh connections you have already made; there is no connect command.
