Milleis Banque API Access & Open Banking Data Sync
Milleis Banque is a French private bank based in Paris, and if you want your account and transaction history in one programmable place, open-banking.io gives you a certificate-free path to it. There is no eIDAS certificate to buy, no PSD2 TPP licence to hold, and no infrastructure to run — you sign up, connect your Milleis Banque profile, and your data flows into a dashboard that only you can decrypt.
open-banking.io covers 2,600+ EU and UK banks for about EUR 3/month. Milleis Banque supports both business and personal accounts, and a single consent stays valid for up to 180 days before you re-approve. No public BIC is listed for Milleis Banque, so the bank is selected by name inside the dashboard rather than by identifier.
How to connect Milleis Banque
Connecting happens entirely in the open-banking.io web dashboard — never through an API call or a key.
- Create your open-banking.io account.
- Set an encryption passphrase. Your keys are generated locally on your device, so the private key never leaves it.
- In the dashboard, search for Milleis Banque and choose the account type — business or personal.
- You are redirected to Milleis Banque's own secure login, where you approve access on the bank's PSD2 consent screen.
- Your accounts sync back into the dashboard, ready to view.
That's it — no redirect you have to build, no OAuth flow to wire up. The bank authenticates you directly, and open-banking.io only ever holds your public key.
Access your data
Reading Milleis Banque data programmatically is an optional step you take after connecting. On the Developers page, create an API key and export a credentials.json — it bundles the API 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. Because the platform is zero-knowledge, an API key alone returns only ciphertext — without your private key, there is nothing readable to leak.
Does open-banking.io see my Milleis Banque login?
No. You authenticate on Milleis Banque's own consent screen. open-banking.io stores only your public key and never your banking credentials.
Do I need a certificate or licence?
No. There is no eIDAS certificate and no TPP registration. Sign up, connect, done.
How long does access last before I re-approve?
Up to 180 days per consent for Milleis Banque, after which you refresh the connection from the dashboard.
