Fintro API Access — Open Banking for Belgium

Fintro is a Belgian banking brand of BNP Paribas Fortis (BIC GEBABEBB), and open-banking.io lets you reach your Fintro data without wrestling with PSD2 certificates, sandboxes, or eIDAS paperwork. You link your accounts once, and both business and personal balances and transactions flow into a single dashboard — then, if you write code, you can read that same data through a CLI, SDK, or REST API. Everything is decrypted on your own device with a key only you hold.

How to connect Fintro

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

  1. Sign up for open-banking.io and set an encryption passphrase. Your cryptographic keys are generated locally, on your device, so the service never sees them.
  2. In the dashboard, choose Fintro from the bank list and select whether you're linking a business or personal account.
  3. You're redirected to Fintro's own secure login, where you approve access on the bank's PSD2 consent screen — your credentials go only to Fintro, never to us.
  4. Once approved, your Fintro accounts sync into the dashboard automatically. Consent lasts up to 180 days, after which you simply re-approve on Fintro's screen.

Access your data

Programmatic access is an optional developer step you take after connecting. From the Developers page, create an API key and export a credentials.json — this bundles the API key together with your private decryption key. With it, run the CLI (openbanking accounts, openbanking transactions, openbanking sync) or call the REST API and SDKs. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your key. Note that the CLI and SDK only read and sync connections you already made in the dashboard — there is no connect command.

Because open-banking.io is zero-knowledge, our servers store only your public key and encrypted blobs. An API key alone returns ciphertext; without your private key, the data stays unreadable — even to us. All of this runs for roughly EUR 3/month across 2,600+ EU and UK banks.

FAQ

Does open-banking.io need an eIDAS certificate for Fintro?

No. It's certificate-free — you approve access directly on Fintro's consent screen, with no QWAC or QSEAL setup on your side.

Can I connect Fintro from the command line?

No. Connecting is done in the dashboard via Fintro's login. The CLI and SDK only read or sync accounts you've already linked.

Can open-banking.io read my Fintro transactions?

No. Data is decrypted locally with a key only you hold. Our servers hold only your public key and encrypted data.
