ASN Bank API Access for Netherlands Open Banking

Bring your ASN Bank data into any product you build with a single, unified open-banking connection. open-banking.io links directly to ASN Bank in the Netherlands so you can read live account information without wrangling the bank's own developer portal, eIDAS certificates, or PSD2 onboarding paperwork. Whether you are reconciling ledgers, powering a budgeting tool, or scoring affordability, the same API surface that serves 2,600+ European banks also serves ASN Bank.

How to connect ASN Bank

1. Create an open-banking.io account and grab your API key.
2. Call the institutions endpoint and select ASN Bank (BIC ASNBNL21).
3. Redirect your user to ASN Bank's secure login to approve access.
4. Receive the returned consent reference and begin pulling data straight away.

What data you can access

Once a customer has authorised the link, you can retrieve their accounts (identifiers, currency, and holder details), current and available balances, and full transaction history for both personal and business accounts. Responses arrive in one consistent schema, so ASN Bank behaves exactly like every other institution in your integration.

Consent and coverage

ASN Bank supports both business and personal account types. A single authorisation stays valid for up to 180 days, the maximum consent window permitted, after which the customer simply re-approves to keep the feed running — no re-integration on your side.

Privacy by design

The platform is zero-knowledge: banking credentials are entered only on ASN Bank's own pages and are never seen or stored by us. There are no eIDAS or QWAC certificates to purchase, host, or renew — the compliance layer is handled for you, so you ship faster and hold less risk.

Pricing

Access starts at roughly EUR 3 per month, with no per-call surcharges or setup fees. One predictable subscription covers ASN Bank alongside the rest of the European network.

Is ASN Bank supported for both personal and business accounts?

Yes. Both account types can be connected and read through the same endpoints.

How long does an ASN Bank consent last?

Up to 180 days per authorisation. When it lapses, the customer re-confirms access in a few taps.

Do I need my own PSD2 licence or certificate?

No. open-banking.io provides the regulated, certificate-free rails, so you can integrate ASN Bank without your own licence.
