Crédit Agricole des Côtes d'Armor Open Banking Access

Pulling your own banking data out of Crédit Agricole des Côtes d'Armor usually means wrestling with PSD2 red tape, TPP certificates and eIDAS paperwork. open-banking.io removes all of that. It gives you a single dashboard to link your Crédit Agricole des Côtes d'Armor accounts and read balances and transactions — for both business and personal accounts — without registering as a licensed provider or holding any certificate of your own.

Everything is encrypted with a key that only ever exists on your device. open-banking.io stores just your public key, so the service itself can never read or decrypt what flows through it. That zero-knowledge design is the whole point: your Crédit Agricole des Côtes d'Armor data stays yours.

How to connect Crédit Agricole des Côtes d'Armor

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 an encryption passphrase. Your encryption keys are generated locally on your own device from that passphrase.
  2. In the dashboard, search for Crédit Agricole des Côtes d'Armor and choose the account type you want to link — business or personal.
  3. You are redirected to Crédit Agricole des Côtes d'Armor's own secure login, where you approve access under standard PSD2 consent. Consent can run for up to 180 days before you re-authorise.
  4. Your accounts sync back into the dashboard, where balances and transactions appear ready to view.

Crédit Agricole des Côtes d'Armor does not publish a public BIC in our reference data, so simply select it by name in the dashboard.

Access your data

Once Crédit Agricole des Côtes d'Armor is connected, developers can optionally read the data 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 directly.

Every request carries your key in the X-Api-Key header, and each response is decrypted locally with your private key. The CLI and SDK only read and sync connections that already exist — they never establish new ones. And an API key on its own returns only ciphertext; without your private key, the data stays unreadable.

All of this runs for around EUR 3/month.

Do I need a TPP certificate or licence?

No. open-banking.io is certificate-free — you approve access directly on Crédit Agricole des Côtes d'Armor's consent screen, with no eIDAS registration required.

Can open-banking.io see my transactions?

No. It holds only your public key. Data is decrypted on your device, so the servers only ever hold ciphertext.

How long does access last before I re-approve?

Up to 180 days per consent, after which you re-authorise with Crédit Agricole des Côtes d'Armor.
