Caisse d'Epargne Hauts de France Open Banking Access

Caisse d'Epargne Hauts de France serves customers across northern France, and open-banking.io lets you reach its account data without wrestling with eIDAS certificates or a PSD2 sandbox. It is a zero-knowledge service covering 2,600+ EU and UK banks: your data is encrypted and decrypted on your own device with a key that never leaves it. Both business and personal accounts are supported, and a single consent stays valid for up to 180 days before you renew it.

How to connect Caisse d'Epargne Hauts de France

Connecting happens entirely in 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 set your encryption passphrase. Your keys are generated locally, so only you can later unlock the data.
  2. In the dashboard, pick Caisse d'Epargne Hauts de France from the bank list and choose your account type (business or personal).
  3. You are redirected to Caisse d'Epargne Hauts de France's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Once approved, your accounts and transactions sync straight into your dashboard.

No credentials ever pass through us — authentication stays between you and the bank.

Access your data

Reading the data programmatically is an optional step you take after connecting. Open the Developers page, create an API key, and export a credentials.json bundle — it holds the API key plus your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests carry the X-Api-Key header, and every response is decrypted locally with your own key. Because our servers only ever hold your public key, an API key on its own returns nothing but ciphertext — the private key that makes it readable stays with you.

All of this runs at roughly EUR 3/month, with no certificate paperwork and no per-call bank fees.

Does Caisse d'Epargne Hauts de France have a BIC I need?

No BIC is required here — you select the bank by name in the dashboard, and the connection is identified for you.

Can I connect both business and personal accounts?

Yes. Caisse d'Epargne Hauts de France exposes both account types; just choose the one you want when adding the connection, or add each separately.

How long does one authorisation last?

Up to 180 days. When it expires, you simply reapprove on the bank's consent screen to keep your dashboard syncing.
