ING Wholesale Banking (Luxembourg) API Access

Bring your ING Wholesale Banking (Luxembourg) data into your own systems without wrestling with certificates, eIDAS setup or bespoke bank integrations. open-banking.io gives you a single, standardised connection to keep corporate account information flowing straight into your tooling — reconciliation, cash reporting, ERPs or dashboards — with ING Wholesale Banking treated exactly like the 2,600+ other institutions on the network.

Wholesale and corporate treasury teams work with high transaction volumes and strict controls. A read-only API feed lets you automate what used to be manual exports, so balances and movements stay current without anyone downloading statements.

Consent and coverage

ING Wholesale Banking (Luxembourg) supports business account types, and a single authorisation stays valid for up to 180 days before you re-confirm. No BIC is required to set up the connection. Coverage spans 2,600+ banks across the EU and UK, so one integration reaches far beyond a single institution.

Privacy by design

We run a zero-knowledge architecture: your credentials go directly to the bank, and open-banking.io never stores them. There are no eIDAS certificates to buy or renew — the certificate-free model removes the heaviest part of PSD2 onboarding while keeping you in control of every consent.

Pricing

One flat rate of roughly EUR 3 per month covers your access — no per-call fees, no enterprise minimums, no surprises.

FAQ

Do I need eIDAS certificates to connect?

No. The certificate-free design means you skip QWAC/QSEAL procurement entirely and connect through the bank's own authentication.

How long does one consent last?

Up to 180 days for ING Wholesale Banking (Luxembourg), after which you simply re-authorise to keep the feed live.

What can I actually read?
