Banque Populaire du Nord API Access & Open Banking

Reaching your Banque Populaire du Nord accounts through a single, privacy-first tool no longer means chasing certificates or PSD2 sandbox credentials. open-banking.io links your Banque Populaire du Nord accounts (BIC CCBPFRPPLIL) alongside 2,600+ other EU and UK banks, so both business and personal balances and transactions land in one dashboard. Every figure is encrypted on your device with a key only you hold — the service is zero-knowledge and certificate-free, storing nothing but your public key.

How to connect Banque Populaire du Nord

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 key pair is generated locally on your device, so no one else — not even open-banking.io — can decrypt what syncs.
  3. Pick Banque Populaire du Nord from the bank list and choose the account type you want to link (business or personal).
  4. Approve on Banque Populaire du Nord's own login. You are redirected to the bank's secure consent screen, where you authenticate and grant PSD2 access directly. open-banking.io never sees your banking credentials.
  5. Accounts sync back into your dashboard. Your consent stays valid for up to 180 days, after which you simply re-approve.

Access your data

Once the connection is live, reading it programmatically is an optional developer step. On the Developers page, create an API key and export a credentials.json — this bundles the API key with your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. Without that private key an API key returns only ciphertext — a direct consequence of the zero-knowledge design. Note the CLI and SDK only read and sync connections you already made in the dashboard; there is no connect command.

All of this runs for roughly EUR 3/month.

Do I need a developer certificate for Banque Populaire du Nord?

No. open-banking.io is certificate-free. You approve access on the bank's own consent screen — no eIDAS certificate or sandbox registration required.

Can open-banking.io read my Banque Populaire du Nord data?

No. Decryption happens on your device with a key only you hold. The servers keep just your public key and encrypted blobs.

How long does access last?
