KBC API Access: Sync Belgian Bank Data Securely

Connect your KBC accounts to any app or spreadsheet and keep Belgian banking data flowing automatically. open-banking.io gives developers, finance teams, and treasurers a single REST API to read balances and transactions from KBC (BIC KREDBEBB) without maintaining eIDAS certificates or wrestling with PSD2 onboarding. Authorise once, then sync on your schedule.

How to connect KBC

  1. Create an open-banking.io account and generate an API key.
  2. Call the connect endpoint and select KBC as your institution.
  3. Approve access in KBC's own secure login (SCA) — your credentials stay with the bank.
  4. Receive an access token and start pulling account, balance, and transaction data.

What data you can access

  • Accounts — IBANs, currency, and product metadata for business and personal accounts.
  • Balances — current and available amounts, refreshed on demand.
  • Transactions — booked and pending entries with counterparties, references, and dates for reconciliation or analytics.

KBC supports a maximum consent window of 180 days, after which the account holder reauthorises with a quick SCA step. The same integration reaches 2,600+ banks across the EU and UK, so adding another institution later means no new plumbing — just another connect call.

Privacy by design

open-banking.io is zero-knowledge: we never see or store your KBC credentials, and account data is passed through, not warehoused. There are no eIDAS or QWAC certificates for you to buy, renew, or manage — the certificate-free architecture removes the heaviest part of PSD2 compliance from your plate.

Simple pricing

One flat plan of roughly EUR 3 per month covers KBC alongside every other supported bank. No per-call fees, no enterprise minimums, no setup charges — predictable cost whether you sync one account or hundreds.

Do I need a PSD2 licence to use this?

No. open-banking.io operates the regulated access layer, so you connect to KBC through our infrastructure without holding your own AISP licence or certificates.

How often can I refresh KBC data?

You can pull fresh balances and transactions on demand within your active consent. When the 180-day window ends, a short reauthorisation restores access.

Does this work for both business and personal accounts?

Yes. KBC exposes both business and personal account types, and the same endpoints handle either once consent is granted.
