KBC Brussels API Access | Open Banking Belgium

Pulling live data out of your KBC Brussels accounts no longer means wrestling with bank-specific portals or PSD2 certificates. With open-banking.io you connect to KBC Brussels through one consistent EU/UK API and keep account information flowing straight into your own tools, dashboards, or bookkeeping stack.

KBC Brussels (BIC KREDBEBB387) is one of 2,600+ institutions reachable from a single integration, so the same code that reads a Belgian account also reaches banks across Europe and the UK.

How to connect KBC Brussels

1. Create an open-banking.io account and grab your API key.
2. Start an authorisation request that points to KBC Brussels.
3. Approve access in KBC Brussels' own secure login — your credentials stay with the bank.

What data you can access

• Accounts — identifiers and metadata for KBC Brussels business and personal accounts.
• Balances — current and available figures, refreshed on demand.
• Transactions — dated, categorised entries with counterparty details for reconciliation.

Consent and coverage

KBC Brussels supports both business and personal account types. A single consent stays valid for up to 180 days before the account holder re-authorises, giving you a long window of uninterrupted syncing without repeated prompts.

Privacy by design

open-banking.io is zero-knowledge: your users' banking credentials are entered only on KBC Brussels' side and never touch our servers. There are no eIDAS or QWAC certificates to buy, register, or renew — the platform handles the regulatory plumbing so you don't manage any PKI yourself.

Pricing

Access starts at roughly EUR 3 per month, with the same flat approach whether you connect one KBC Brussels account or scale across the full 2,600+ bank network. No per-certificate fees, no surprise tiers.
