SNS Bank API Access: Sync Accounts & Transactions

Bringing SNS Bank data into your own tools no longer means chasing bank partnerships or juggling eIDAS certificates. open-banking.io gives you a single, unified endpoint to read account information from SNS Bank in the Netherlands, so you can automate reconciliation, feed dashboards, or power an app without leaving the regulated open-banking rails.

SNS (BIC SNSBNL2A) is one of thousands of institutions reachable through the same integration, meaning the code you write for SNS carries straight over to the rest of Europe.

How to connect SNS Bank

  1. Create an open-banking.io account and generate your API key.
  2. Call the connect endpoint and select SNS Bank (SNSBNL2A) as the target institution.
  3. Redirect your user to the SNS authorisation screen, where they approve access with their own banking credentials.
  4. Receive the returned reference and start pulling data through the standardised API.

Both personal and business SNS accounts are supported, so the same flow works for retail apps and corporate finance tooling alike.

What data you can access

Once a customer consents, you can retrieve:

  • Accounts — IBANs, account names, currency and product type
  • Balances — current and available amounts, refreshed on demand
  • Transactions — booked and pending entries with counterparties, dates and references

SNS grants access under a single authorisation valid for up to 180 days. After that window the customer simply re-confirms consent to keep the connection live. Coverage spans SNS's Dutch personal and business accounts, all through the account-information rails their PSD2 interface exposes.

Privacy by design

open-banking.io is zero-knowledge: your users authenticate directly with SNS, and we never store their banking passwords. There are no eIDAS or QWAC certificates for you to buy, host or renew — that regulatory overhead sits with us, not you. Data flows through encrypted channels straight to your application.

Pricing

One flat subscription of roughly EUR 3 per month covers access to SNS Bank and 2,600+ other European institutions. No per-call surcharges, no setup fees, no long-term lock-in.

FAQ

Do I need a contract with SNS Bank?

No. open-banking.io holds the necessary licences, so you connect to SNS through our API without any direct bank agreement.

How often can I refresh SNS data?

As often as your use case needs within the 180-day consent period; balances and transactions are fetched live on each request.

Are business accounts included?

Yes. Both personal and business SNS accounts work through the same connection flow.
