ING Wholesale Banking API Access (Slovakia)

Bringing your ING Wholesale Banking (Slovakia) data into your own systems no longer requires a bank-issued certificate or a bespoke integration project. Through open-banking.io you can link the corporate accounts ING runs for your Slovak entity and keep balances and transaction history flowing into whatever tools your finance team already uses — accounting software, treasury dashboards, cash-forecasting models, or a data warehouse.

How to connect ING Wholesale Banking

1. Create an account at open-banking.io and open the connection wizard.
2. Search for ING Wholesale Banking and select the Slovakia entity.
3. Authenticate directly with ING using your normal corporate banking credentials — open-banking.io never sees or stores them.
4. Approve the accounts you want to share and confirm the consent window.
5. Start pulling data through the unified API or export it straight into your target system.

What data you can access

Once the link is live, open-banking.io exposes the core corporate datasets:

• Accounts — the business accounts held with ING Wholesale Banking, with identifiers and metadata.
• Balances — current and available figures for reconciliation and liquidity views.
• Transactions — booked and pending entries with dates, counterparties, and reference details.

Consent and coverage

ING Wholesale Banking (Slovakia) supports business account types, and a single authorisation stays valid for up to 180 days before ING requires you to re-confirm — one of the longer consent windows available, which means fewer interruptions to your automated feeds. open-banking.io reaches 2,600+ banks across the EU and UK through one consistent interface, so adding ING alongside your other banking relationships takes the same few steps.

Privacy by design

The platform is zero-knowledge: credentials go straight to ING, and account data passes through encrypted, without open-banking.io building a profile of it. There are no eIDAS certificates, QWAC files, or PSD2 licensing hurdles for you to manage — the compliance layer is handled for you.

Pricing

Access is a flat ~EUR 3 per month, with no per-call fees or enterprise contracts, so the cost stays predictable whether you connect one ING account or several.

FAQ

Do I need a certificate or a PSD2 licence to connect ING Wholesale Banking?

No. open-banking.io is certificate-free and handles the regulatory access layer, so you only need your existing ING corporate login.

How long does my consent last?

Up to 180 days per authorisation. After that, ING asks you to renew, and open-banking.io will prompt you before the window closes.

Which ING Wholesale Banking data can I retrieve?

Business accounts, their balances, and full transaction history — enough to automate reconciliation, reporting, and cash management.
