ING (Luxembourg) API Access | Open Banking Sync

Pull your ING (Luxembourg) account data into any product or workflow through a single, standardised open-banking connection. Whether you are reconciling ledgers, building a treasury dashboard or scoring affordability, open-banking.io lets you read live ING data without wrestling with eIDAS certificates or bank-specific onboarding.

ING in Luxembourg operates under the BIC CELLLULL, and the API surfaces both personal and business relationships through the same endpoints, so you write your integration once and reuse it across account types.

How to connect ING

1. Create your open-banking.io account and generate an API key.
2. Call the connect endpoint with ING (Luxembourg) as the target institution.
3. Redirect the account holder to ING's own login and strong customer authentication.
4. Receive the consent token once the customer approves access.
5. Query accounts, balances and transactions — no certificates, no manual paperwork.

What data you can access

• Accounts — identifiers, IBANs, currency and product metadata.
• Balances — booked and available amounts, refreshed on demand.
• Transactions — dated entries with counterparties, references and amounts for reconciliation and analysis.

Consent and coverage

Each ING authorisation lasts up to 180 days before the customer re-confirms, keeping you aligned with PSD2 rules while minimising re-prompts. open-banking.io reaches 2,600+ banks across the EU and UK, so ING (Luxembourg) sits alongside the rest of your customers' institutions behind one contract and one API.

Privacy by design

The platform is zero-knowledge: credentials go straight to ING and are never seen or stored by us. Because access is certificate-free, there is no eIDAS/QWAC provisioning to manage — you skip the slowest part of most open-banking projects and stay focused on your product.

Pricing

Flat, predictable access from roughly EUR 3 per month — no per-call surprises and no enterprise minimums to get started.

Does connecting ING require an eIDAS certificate?

No. open-banking.io is certificate-free, so you authenticate customers and read ING data without provisioning QWAC/QSEAL certificates.

Can I connect both personal and business ING accounts?

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

How long does an ING consent stay valid?

Up to 180 days per authorisation, after which the account holder re-confirms access to continue syncing.
