BNP Paribas Personal Finance Open Banking Access

Pulling data out of BNP Paribas Personal Finance in Germany usually means wrestling with PSD2 certificates, sandbox registrations and per-bank paperwork. open-banking.io removes all of that. It gives you a single, standardised way to read your BNP Paribas Personal Finance balances and transactions across more than 2,600 EU and UK banks — without eIDAS certificates, without a regulated TPP licence, and without ever handing your data to a third party in readable form. Everything is decrypted locally with a key only you hold, so the service itself only ever stores your public key.

BNP Paribas Personal Finance supports both business and personal account types here, and a single consent lasts up to 180 days before you re-authorise. No BIC is required to get started.

How to connect BNP Paribas Personal Finance

Connecting happens entirely inside the open-banking.io dashboard — there is no API call, code or key involved in this step.

  1. Sign up at open-banking.io and set your encryption passphrase. Your keys are generated on your own device at this moment.
  2. In the dashboard, search for BNP Paribas Personal Finance and choose whether you are linking a business or personal account.
  3. You are redirected to BNP Paribas Personal Finance's own secure login, where you approve access on the bank's PSD2 consent screen.
  4. Once approved, your accounts sync back into your dashboard and stay refreshed for the life of the consent.

That's the whole flow — you authorise directly with the bank, and open-banking.io never sees your login.

Access your data

Reading the data programmatically is an optional step you take after the connection exists. 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 you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API directly. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. Without that private key, an API key alone returns only ciphertext.

All of this runs for roughly EUR 3/month.

Do I need a PSD2 certificate for BNP Paribas Personal Finance?

No. open-banking.io is certificate-free — you approve access on the bank's consent screen and nothing more.

Can open-banking.io read my BNP Paribas Personal Finance data?
