Hello Bank Belgium: API Access & Open Banking Data

Hello bank! is BNP Paribas Fortis' fully mobile bank in Belgium, and open-banking.io lets you reach your Hello Bank data without wrestling with eIDAS certificates, sandbox registrations, or a bank developer portal. It is a zero-knowledge, certificate-free bridge to 2,600+ EU and UK banks: your account information is decrypted on your own device with a key that never leaves it. open-banking.io's servers only ever hold your public key, so they can shuttle ciphertext around but can never read a single balance or transaction.

Hello Bank in Belgium operates under BIC GEBABEBB and covers personal accounts. Each PSD2 consent you approve stays valid for up to 180 days, after which you simply re-confirm to keep your data flowing.

How to connect Hello Bank

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 your encryption passphrase. Your cryptographic keys are generated locally, on your own device, at this moment.
  2. Open the dashboard, choose Hello Bank from the bank list, and select the personal account type.
  3. You are redirected to Hello Bank's own secure login, where you authenticate and approve access on the bank's PSD2 consent screen.
  4. Once you confirm, your Hello Bank accounts sync straight into your dashboard, ready to view.

Access your data

Reading Hello Bank data programmatically is an optional step you take after the connection exists. On the Developers page, create an API key and export a credentials.json — this file bundles the 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. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. Without that private key an API key alone returns only ciphertext — which is exactly what keeps the service zero-knowledge.

All of this runs for roughly EUR 3/month, with no per-connection or certificate fees.

Do I need a developer account to connect Hello Bank?

No. Connecting is done in the dashboard by approving access on Hello Bank's own login. API keys only matter for reading data afterwards.

Can open-banking.io see my Hello Bank transactions?

No. Data is decrypted on your device with a key only you hold; the servers store nothing but your public key.

Up to 180 days per approval, then you re-confirm on Hello Bank's consent screen.
