ING API Access for the Netherlands | Open Banking

Pulling live data out of ING in the Netherlands no longer means wrestling with eIDAS certificates or a lengthy TPP onboarding. open-banking.io gives you a single, standards-based endpoint to sync ING account information into your own product, spreadsheet, or ledger. Point your integration at ING, let the account holder approve, and structured banking data starts flowing within minutes.

Because the plumbing is handled for you, a small fintech, an accountant, or a solo developer can read ING data on the same footing as a large institution — no bank-specific paperwork required.

How to connect ING

  1. Create an open-banking.io account and generate an API key.
  2. Call the connect endpoint with ING's identifier (BIC INGBNL2A).
  3. Redirect the customer to ING's own login so they authorise access.
  4. Receive the callback and start querying accounts, balances, and transactions.

What data you can access

  • Accounts — IBANs, product names, currency, and holder details for business and personal ING accounts.
  • Balances — booked and available amounts, refreshed on demand.
  • Transactions — dated entries with counterparties, references, and amounts for reconciliation or categorisation.

ING supports both business and personal accounts through the API. A single customer authorisation stays valid for up to 180 days, after which the account holder simply re-approves. ING is one of 2,600+ banks reachable across the EU and UK from the same integration, so adding neighbouring institutions later means no new code.

Privacy by design

The service is zero-knowledge: credentials are entered only on ING's own pages, and we never see or store a customer's banking password. There are no QWAC or QSEAL certificates to buy, renew, or rotate — the compliance layer is abstracted away, leaving you with clean data and far less risk to manage.

Pricing

Access is a flat ~EUR 3/month, with no per-call surcharges or setup fees, so costs stay predictable whether you sync one ING account or hundreds.

FAQ

Do I need a licence to read ING data?

No. open-banking.io provides the regulated access layer, so you connect to ING without holding your own TPP licence or certificates.

Which ING account types are supported?

Both business and personal ING (Netherlands) accounts are available, covering accounts, balances, and transaction history.

How often must customers re-authorise?

ING consent lasts up to 180 days; after that the customer re-confirms access in a single tap.
