Arkea Banque Entreprises API Access & Open Banking

Arkea Banque Entreprises serves French companies and institutional clients as part of the Crédit Mutuel Arkéa group, and open-banking.io gives you a clean, PSD2-compliant way to reach that data. There are no eIDAS certificates to buy, no bank sponsorship to negotiate, and no infrastructure to run. You connect once, and your business balances and transactions flow into a dashboard where only you hold the key to decrypt them.

Because open-banking.io is zero-knowledge, its servers never see your statements in the clear. They store only your public key; the private key that unlocks your data is generated on your own device and never leaves it.

How to connect Arkea Banque Entreprises

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 an open-banking.io account.
  2. Set an encryption passphrase. Your key pair is created locally on your device from this passphrase.
  3. In the dashboard, search for Arkea Banque Entreprises and choose the business account type — the accounts this bank exposes over PSD2.
  4. You are redirected to Arkea Banque Entreprises's own secure login and consent screen, where you approve access directly with the bank.
  5. Your approved accounts sync back into your dashboard.

Consent lasts up to 180 days, after which you simply re-approve on the bank's screen to keep the connection live. (Note: Arkea Banque Entreprises has no single retail BIC published here — none is needed for the dashboard flow.)

Access your data

Reading the data programmatically is an optional step for developers, and only after a connection exists. Open the Developers page, create an API key, and export a credentials.json that bundles that key with your private decryption key. From there use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Every request carries the X-Api-Key header, and each response is decrypted locally with your own key — an API key by itself only ever returns ciphertext. There is no connect command; the tooling reads and syncs connections you already made in the dashboard.

All of this runs for roughly EUR 3/month.

Do I need an eIDAS certificate?

No. open-banking.io handles the regulated access layer, so you connect Arkea Banque Entreprises without any certificate of your own.

Can open-banking.io read my transactions?

No. It holds only your public key. Decryption happens on your device with a private key that never leaves it.

Can I connect a personal account?

Arkea Banque Entreprises is exposed here for business accounts, matching its corporate and institutional focus.
