Caisse d'Epargne Normandie API & Open Banking Access

Pulling your Caisse d'Epargne Normandie balances and transactions into your own tools usually means certificates, sandbox registrations and PSD2 paperwork. open-banking.io removes all of that. It links your Caisse d'Epargne Normandie accounts (BIC CEPAFRPP142) through the regulated PSD2 consent flow, then keeps them in sync in a dashboard where every figure is decrypted on your device with a key only you hold. Both business and personal accounts are supported, and a single approval stays valid for up to 180 days before you renew it.

How to connect Caisse d'Epargne Normandie

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 set your encryption passphrase. Your key pair is generated locally, so only your public key ever leaves your device.
  2. In the dashboard, search for Caisse d'Epargne Normandie and choose the account type you want to link — business or personal.
  3. You are redirected to Caisse d'Epargne Normandie's own secure login, where you authenticate and approve access on the bank's consent screen.
  4. Control returns to open-banking.io and your accounts begin syncing automatically. Transactions and balances appear in your dashboard, encrypted end to end.

Access your data

Once Caisse d'Epargne Normandie is connected, reading the data programmatically is an optional developer step. Open the Developers page, create an API key and export a credentials.json that bundles the key with your private decryption key. From there the CLI works out of the box:

openbanking accounts
openbanking transactions
openbanking sync

An SDK and REST API are available too. Every request carries your X-Api-Key header, and each response is decrypted locally with your private key. An API key on its own only returns ciphertext — without your key the data stays unreadable, even to open-banking.io.

The service is zero-knowledge and certificate-free: no eIDAS certificate, no QWAC, and the servers store only your public key. All of this runs for roughly EUR 3/month, across 2,600+ supported EU and UK banks.

Does open-banking.io see my Caisse d'Epargne Normandie data?

No. Data is encrypted with a key generated on your device. The servers hold only your public key and can never decrypt your accounts.

Can I connect a business account?

Yes. Caisse d'Epargne Normandie supports both business and personal accounts; pick the type when you select the bank in the dashboard.

How long does access last?

Up to 180 days per consent. When it expires, reauthorise on Caisse d'Epargne Normandie's login screen to continue syncing.
