iBanFirst API Access | Open Banking Made Simple

Reaching your iBanFirst account data no longer means wrestling with PSD2 certificates or building a bank integration from scratch. open-banking.io gives you a single, privacy-first path to your iBanFirst balances and transactions — and, when you want it, a clean developer interface on top. iBanFirst supports both business and personal accounts (BIC FXBBBEBBXXX), and a single approval keeps your connection live for up to 180 days before you renew.

Everything runs on a zero-knowledge, certificate-free design. Your encryption keys are generated on your own device, so open-banking.io only ever holds your public key — it cannot read or decrypt anything you sync. For one flat price of around EUR 3/month you get access to 2,600+ EU and UK banks, iBanFirst included.

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 your encryption passphrase. Your private key is created locally and never leaves your device.
  2. In the dashboard, search for iBanFirst and choose your account type — business or personal.
  3. You are redirected to iBanFirst's own secure login, where you approve access under PSD2 consent. Your credentials go only to your bank.
  4. Once approved, your iBanFirst accounts sync straight into your dashboard, ready to view.

Access your data

Once 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 the API key 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 each response is decrypted locally with your own key. The API key alone only ever returns ciphertext — without your private key, nobody can read it. Note there is no connect command: the CLI and SDK read and refresh existing connections, while connecting a bank always happens in the dashboard.

FAQ

Do I need an eIDAS certificate for iBanFirst?

No. open-banking.io is certificate-free — you approve access on iBanFirst's own consent screen, with no PSD2 certificate to obtain or maintain.

Can open-banking.io see my iBanFirst transactions?

No. It is zero-knowledge: your data is decrypted only on your device with a key that never leaves it. The service stores only your public key.

How long does a connection last?

Up to 180 days per approval. When the consent window closes, you simply re-approve from the dashboard to keep syncing.
