Argenta API Access: Sync Belgian Bank Data Fast

Pull live financial data straight from Argenta into your own product. open-banking.io gives you a single API to sync Argenta accounts across Belgium — no eIDAS certificates, no bank-by-bank integration work, and no scraping. Whether you are building bookkeeping automation, a treasury dashboard, or an affordability check, you read the same clean JSON for Argenta as you do for every other bank on the network.

Argenta is identified by the BIC ARSPBE22, and both personal and business account types are supported. Once a customer grants consent, their data flows through in near real time.

How to connect Argenta

  1. Sign up for an open-banking.io account and grab your API key.
  2. Call the connect endpoint with the Argenta BIC ARSPBE22.
  3. Redirect your customer to Argenta's own secure login to authorise access.
  4. Receive the consent token and start requesting accounts, balances and transactions.

No onboarding calls, no sandbox paperwork — you can be reading production data the same day.

What data you get

  • Accounts — IBANs, account names, currency and holder details for personal and business profiles.
  • Balances — current and available balances, refreshed on demand.
  • Transactions — booked and pending entries with amounts, counterparties, dates and reference text.

Argenta consent lasts up to 180 days before the customer needs to re-authorise, matching Belgian PSD2 practice. open-banking.io connects to 2,600+ banks across the EU and UK, so adding the next institution is just another BIC — your integration never changes.

Privacy by design

We run a zero-knowledge model: credentials go directly to Argenta, never to us, and consent tokens stay scoped to what your customer approved. The service is certificate-free, so you skip the cost and delay of managing QWAC/QSEAL certificates yourself. You handle data; we handle the plumbing.

Pricing

One flat plan of roughly EUR 3 per month covers Argenta and every other supported bank. No per-call surcharges, no setup fee, no minimum volume.

Do I need my own PSD2 licence?

No. open-banking.io operates the regulated access layer, so you connect to Argenta under our infrastructure without holding a licence.

How often can I refresh Argenta data?

As often as your use case needs, within Argenta's PSD2 rate limits. Balances and transactions are fetched live when you call.

Does this work for Argenta business accounts?

Yes. Both personal and business account types are supported through the same endpoints and the same BIC.
