Deutsche Bank Poland Open Banking & API Access

Deutsche Bank operates in Poland as a corporate and institutional specialist, and open-banking.io lets you reach its account data through a single, privacy-first workspace. Rather than juggling bank-specific portals or PSD2 certificates, you link Deutsche Bank (Poland) once and read balances and transactions on your own terms. Because Deutsche Bank in Poland serves the corporate segment, open-banking.io connects business accounts here, with a PSD2 consent that stays valid for up to 180 days before you renew it. No published BIC is required to set the connection up.

The whole service is built around zero knowledge: your data is encrypted and decrypted locally with a key that never leaves your device, so open-banking.io only ever holds your public key. It is certificate-free, covers 2,600+ European banks, and costs around EUR 3/month.

How to connect Deutsche Bank

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 keys are generated right there on your own device.
  2. Open the dashboard, search for Deutsche Bank (Poland), and choose the business account type you want to link.
  3. You are redirected to Deutsche Bank's own secure login, where you approve the PSD2 access request on the bank's consent screen.
  4. Once approved, your accounts sync back into your dashboard and stay available for the life of the consent.

Access your data

After the connection exists, developers can optionally read it programmatically. From the Developers page, create an API key and export a credentials.json bundle — this contains the API key plus your private decryption key. With it you can use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Every request authenticates with the X-Api-Key header, and each response is decrypted locally with your own key. Without that private key, an API key alone only ever returns ciphertext — which is exactly why the model stays zero-knowledge.

Does open-banking.io work with Deutsche Bank's Polish corporate accounts?

Yes. It links business accounts at Deutsche Bank (Poland) and syncs balances and transactions into your dashboard.

How long does one authorisation last?

A Deutsche Bank PSD2 consent remains active for up to 180 days, after which you re-approve on the bank's login screen.

Can the CLI connect the bank for me?

No. The CLI and SDK only read and sync existing connections — connecting Deutsche Bank always happens in the dashboard.
