Nexent Bank Open Banking & API Access (Netherlands)

Reach your Nexent Bank accounts in the Netherlands without wrestling with PSD2 certificates, eIDAS onboarding, or a sandbox waitlist. open-banking.io gives you a single, private doorway to Nexent Bank (BIC FBHLNL2A) covering both business and personal accounts, with balances and transactions flowing straight into your dashboard once you approve access.

Nexent Bank grants a consent that lasts up to 180 days, so you set it once and let your data refresh for nearly half a year before you renew. And because open-banking.io is zero-knowledge, the service only ever holds your public key — the numbers stay yours.

How to connect Nexent Bank

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

  1. Sign up for open-banking.io and open the web dashboard.
  2. Set your encryption passphrase. Your keys are generated on your own device, so nobody at open-banking.io can read what comes back.
  3. In the dashboard, choose Nexent Bank and select whether you're linking a business or personal account.
  4. You're redirected to Nexent Bank's own secure login, where you approve the PSD2 access request directly with the bank.
  5. Your accounts sync into the dashboard, ready to view.

That's the whole flow — you authenticate on Nexent Bank's screen, not ours.

Access your data

Once a connection exists, developers can optionally read it programmatically. On the Developers page, create an API key and export a credentials.json — this bundles the API key together with your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), 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 returns only ciphertext — without your private key there is nothing readable to see. The CLI and SDK read and sync existing links; they never create the connection itself.

All of this runs for around EUR 3/month.
