SNS Bank Open Banking & API Access | open-banking.io

Reaching your SNS Bank data no longer means wrestling with eIDAS certificates or PSD2 registrations. open-banking.io gives you a single, privacy-first route to your Dutch account information — balances and transactions for both business and personal SNS Bank accounts (BIC SNSBNL2A). Everything is encrypted on your own device with a key only you hold, so the service can never read what flows through it.

How to connect SNS Bank

Connecting happens entirely in the open-banking.io dashboard — there is no code, endpoint, or API key involved in this step.

  1. Sign up for open-banking.io and set your encryption passphrase. Your keys are generated locally on your device.
  2. In the dashboard, choose SNS Bank and select the account type you want to link — business or personal.
  3. You're redirected to SNS Bank's own secure login, where you approve access under PSD2. Your credentials stay with the bank; open-banking.io never sees them.
  4. Once you approve, your accounts sync straight into your dashboard. The consent you grant lasts up to 180 days, after which you simply re-approve on SNS Bank's screen.

Access your data

Want to pull SNS Bank data programmatically? That's an optional developer step after the connection above already exists. Open the Developers page, create an API key, and export a credentials.json — this bundles your API key together with your private decryption key. From there:

  • Use the CLI: openbanking accounts, openbanking transactions, or openbanking sync.
  • Or reach for an SDK or the REST API.

Every request carries the X-Api-Key header, and each response is decrypted locally with your own key. An API key on its own only ever returns ciphertext — without your private key, the data is unreadable, even to open-banking.io's servers, which hold only your public key.

Pricing & privacy

At roughly EUR 3/month, open-banking.io covers 2,600+ EU/UK banks. It is zero-knowledge and certificate-free: no QWAC/QSEAL setup, no bank-by-bank onboarding, and no third party able to decrypt your SNS Bank information.

Do I need a PSD2 certificate for SNS Bank?

No. open-banking.io handles the regulated access layer; you just approve consent on SNS Bank's login screen.

Can I connect SNS Bank using the CLI?

No. Connecting is done in the dashboard. The CLI and SDK only read or sync connections that already exist.

Can open-banking.io read my SNS Bank data?

No. Data is decrypted only on your device with a key you alone hold.
