ING Belgium API Access & Open Banking Integration

Reaching your ING (Belgium) accounts programmatically usually means wrestling with PSD2 certificates, sandbox registrations and a developer onboarding queue. open-banking.io removes all of that. It gives you a single, encrypted view of your ING data (BIC BBRUBEBB) across both business and personal accounts, without you ever handling an eIDAS certificate or sharing a banking password. Everything is decrypted on your own device with a key that never leaves it — open-banking.io stores only your public key, so it can never read what flows through it.

How to connect ING

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

  1. Sign up for open-banking.io and set an encryption passphrase. Your cryptographic keys are generated locally, on your own device.
  2. In the dashboard, choose ING (Belgium) and select the account type you want to link — business or personal.
  3. You are redirected to ING's own secure login, where you approve access on the bank's genuine PSD2 consent screen. Your credentials are entered only on ING's site.
  4. Once approved, your ING accounts and transactions sync straight into your dashboard. A single consent stays valid for up to 180 days before ING asks you to reauthorise.

Access your data

Programmatic access is an optional step you take after the connection exists. Open 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, use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API directly. Every request carries your key in the X-Api-Key header, and each response is decrypted locally with your private key. The CLI and SDK only read and sync connections you already established in the dashboard — they never create them. An API key on its own returns nothing but ciphertext; without your private key the data stays unreadable, which is exactly what zero-knowledge means.

At around EUR 3/month, this covers ING alongside 2,600+ other EU and UK banks under one certificate-free subscription.

Do I need a PSD2 certificate to access ING?

No. open-banking.io handles the regulated connection; you approve access on ING's own consent screen and never touch a certificate.

Can open-banking.io see my ING transactions?

No. Data is decrypted on your device with a key only you hold. The service keeps only your public key.

How long does ING access last?

Up to 180 days per consent, after which you simply reauthorise ING from the dashboard.
