BNP Paribas Poland: API Access & Open Banking Data

BNP Paribas Bank Polska is one of the country's largest universal banks, and if you keep business or personal accounts there, open-banking.io lets you pull that account and transaction data into one place under PSD2 — no bank certificate, no eIDAS QWAC, and no developer onboarding. You point-and-click your way to a live connection, and every figure that reaches you is decrypted on your own machine with a key that never leaves it.

How to connect BNP Paribas

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 locally on your device, so open-banking.io only ever holds your public key.
  2. In the dashboard, choose BNP Paribas (Poland) and select the account type you hold — business or personal.
  3. You are redirected to BNP Paribas's own secure login, where you approve access on the bank's PSD2 consent screen. Your credentials go to the bank, never to us.
  4. Your approved accounts sync straight into your dashboard.

Consent under PSD2 lasts up to 180 days, after which you simply repeat the approval on BNP Paribas's screen to keep the data flowing. BNP Paribas Poland does not publish a single fixed BIC for this purpose, so none is required here.

Access your data

Reading the data programmatically is an optional step for developers, and only after a connection already exists. Open 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. Requests carry your key in the X-Api-Key header, and every response is decrypted locally with your private key. The CLI and SDK only read and sync connections you already made in the dashboard — there is no connect command. An API key on its own returns nothing but ciphertext; without your private key the data stays unreadable.

Does open-banking.io see my BNP Paribas data?

No. The service is zero-knowledge and holds only your public key, so decryption always happens on your device.

Do I need a bank certificate or license?

No. open-banking.io is certificate-free — you approve access directly on BNP Paribas's consent screen, nothing more.

What does it cost?

Around EUR 3 per month for access across 2,600+ EU and UK banks.
