Crédit Agricole de Normandie Seine API & Open Banking

Reach your Crédit Agricole de Normandie Seine accounts through a single, privacy-first workspace. open-banking.io links to the regional Caisse under PSD2 and streams your balances and transactions into one dashboard — covering both business and personal accounts. There is no certificate to register and no eIDAS setup: everything is decrypted on your own device with a key that never leaves it.

How to connect Crédit Agricole de Normandie Seine

Connecting happens entirely inside the open-banking.io dashboard — there is no endpoint to call and no key to paste.

  1. Create an open-banking.io account and set your encryption passphrase. Your key pair is generated locally; only your public key is ever uploaded.
  2. In the dashboard, search for Crédit Agricole de Normandie Seine and choose the account type you hold (business or personal).
  3. You are redirected to Crédit Agricole de Normandie Seine's own secure login to approve access (PSD2 consent). You authenticate directly with the bank — open-banking.io never sees your credentials.
  4. Approve, and your selected accounts sync back into your dashboard. The consent lasts up to 180 days, after which you simply re-approve on the bank's screen.

Access your data

Once a connection exists, developers can read it programmatically — this step is optional. On the Developers page, create an API key and export a credentials.json, which bundles the API key together with your private decryption key. Then use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests carry your key in the X-Api-Key header, and every response is decrypted locally with your private key. The CLI and SDK only read and sync connections you already approved — they never create one. An API key on its own returns ciphertext; without your private key, nothing is readable.

Crédit Agricole de Normandie Seine has no published BIC in our reference data, so selection is by name in the dashboard rather than by BIC.

Does open-banking.io store my banking password?

No. You authenticate on Crédit Agricole de Normandie Seine's own consent page. open-banking.io holds only your public key and encrypted data it cannot read.

Can I connect both a business and a personal account?

Yes. Crédit Agricole de Normandie Seine supports both. Add each account type as its own connection in the dashboard.
