Keytrade Bank API Access & Open Banking Data

Keytrade Bank is Belgium's online-first bank, and open-banking.io lets you reach its account data without maintaining PSD2 certificates or running your own bank integration. You link Keytrade Bank once through a secure consent flow, and your balances and transactions sync into a dashboard where everything is decrypted locally with a key only you hold. Both business and personal Keytrade Bank accounts are supported, and a single consent stays valid for up to 180 days before you re-approve.

How to connect Keytrade 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 keys are generated on your own device, so the service never sees them.
  2. In the dashboard, choose Keytrade Bank (BIC KEYTBEBBXXX) and select whether you're linking a business or personal account.
  3. You're redirected to Keytrade Bank's own secure login, where you approve access under PSD2.
  4. Once approved, your Keytrade Bank accounts sync back into your dashboard and refresh automatically for the life of the 180-day consent.

Access your data

Reading Keytrade Bank data programmatically is an optional step you take after connecting. On the Developers page, create an API key and export a credentials.json — it bundles that API key together with your private decryption key. From there you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests authenticate with the X-Api-Key header, and every response is decrypted locally on your machine. Without your private key, an API key alone returns only ciphertext.

That's the point of the zero-knowledge, certificate-free design: open-banking.io stores only your public key and can never read your Keytrade Bank data. Access runs about EUR 3/month across 2,600+ supported European banks.

Does open-banking.io see my Keytrade Bank data?

No. Data is decrypted on your device with a key only you hold. The servers keep just your public key and encrypted blobs.

Can I connect Keytrade Bank from the CLI?

No. The CLI and SDK only read and sync existing connections. Linking Keytrade Bank always happens in the dashboard via the bank's own consent screen.

How long does access last?

A Keytrade Bank consent is valid for up to 180 days. After that you re-approve on Keytrade Bank's login to keep syncing.
