Arkea Banque Privee API Access & Open Banking

Arkea Banque Privee serves French private-banking clients, and its account data is exactly the kind of information you want under your own control rather than scattered across spreadsheets. open-banking.io lets you reach that data through a single certificate-free service that covers 2,600+ EU and UK banks. There are no eIDAS certificates to buy, no regulator sandbox to join, and no plaintext ever leaving your device: your bank data is decrypted locally with an encryption key that only you hold.

Because the platform is zero-knowledge, its servers store only your public key. They can relay ciphertext but can never read a single Arkea Banque Privee balance or transaction.

How to connect Arkea Banque Privee

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 on your own device at that moment.
2. In the dashboard, search for Arkea Banque Privee and choose the personal account type (personal accounts are supported here).
3. You are redirected to Arkea Banque Privee's own secure login, where you approve access under PSD2. This consent lasts up to 180 days, after which you simply renew it.
4. Your approved accounts sync straight back into your dashboard, ready to view.

Arkea Banque Privee does not publish a BIC for this connection, so none is required — selecting the bank by name in the dashboard is all it takes.

Access your data

Once the connection exists, developers can optionally read it programmatically. On 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 sends the X-Api-Key header, and each response is decrypted locally with your own key — an API key alone only ever returns ciphertext. The CLI and SDK read and sync existing connections; they never create them.

All of this runs for roughly EUR 3 per month.

Is my Arkea Banque Privee data readable by open-banking.io?

No. The service is zero-knowledge and holds only your public key, so it stores encrypted data it cannot decrypt.

Do I need an eIDAS certificate?

No. open-banking.io is certificate-free; you only approve access on the bank's own consent screen.

How long does access last?

Up to 180 days per consent, then you re-approve on Arkea Banque Privee's login page.
