iBanFirst API Access & Open Banking Integration

Need programmatic access to your iBanFirst accounts? open-banking.io lets you link iBanFirst once and then read balances and transactions on your own terms. It is a zero-knowledge, certificate-free service covering 2,600+ EU and UK banks, so there are no eIDAS certificates to buy and no PSD2 licence to maintain. Your data is encrypted on your device with a key only you hold, which means iBanFirst information stays private even from open-banking.io itself.

iBanFirst (BIC FXBBBEBBXXX) supports both business and personal account access, with consent valid for up to 180 days before you re-approve.

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 cryptographic keys are generated locally on your own device.
  2. In the dashboard, choose iBanFirst and select the account type you need (business or personal).
  3. You are redirected to iBanFirst's own secure login, where you approve access under PSD2 — your credentials are only ever entered on the bank's page.
  4. Once approved, your iBanFirst accounts sync into your open-banking.io dashboard and stay refreshed for the length of the 180-day consent.

Access your data

After your iBanFirst connection is live, developers can optionally read it programmatically. On the Developers page, create an API key and export a credentials.json — this bundles the API key plus your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API directly.

Every request authenticates with the X-Api-Key header, and each response is decrypted locally with your own key. That is the whole point of the zero-knowledge design: the API key alone only ever returns ciphertext — without your private key the payload is unreadable, even to the servers that store it. The CLI and SDK read and sync existing connections; they never create one.

FAQ

Do I connect iBanFirst using an API key?

No. You link iBanFirst in the dashboard and approve on iBanFirst's own consent screen. The API key is only for reading data afterwards.

Can open-banking.io read my iBanFirst data?

No. It holds only your public key. Decryption happens on your device with a key that never leaves it.

What does it cost?

Around EUR 3 per month for access across all supported banks, including iBanFirst.
