Deutsche Bank Spain API Access & Open Banking

Reaching account data from Deutsche Bank in Spain no longer means chasing eIDAS certificates or building a PSD2 stack from scratch. open-banking.io gives you one certificate-free path to Deutsche Bank balances and transactions across the Spanish market — for personal and business accounts alike — with every byte decrypted on your own machine. The service reaches 2,600+ banks in the EU and UK, and Deutsche Bank Spain (BIC DEUTESBBXXX) is one of them.

The model is deliberately zero-knowledge: your encryption keys are created on your device, and open-banking.io only ever holds your public key. It can store your account data, but it can never read it.

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 an encryption passphrase. Your private key is generated locally from it and never leaves your device.
  2. In the dashboard, choose Deutsche Bank (Spain) and select the account type you want to link — business or personal.
  3. You are redirected to Deutsche Bank's own secure login, where you approve access under PSD2.
  4. Once you consent, your accounts sync straight into your dashboard. Consent stays valid for up to 180 days, after which you simply re-approve on the bank's screen.

Access your data

Once the connection exists, reading it programmatically is an optional developer step. On the Developers page, create an API key and export a credentials.json — this bundles the API key with your private decryption key. From there:

  • Use the CLI: openbanking accounts, openbanking transactions, openbanking sync.
  • Or call the REST API / an SDK, passing your key in the X-Api-Key header.

Every response is decrypted locally with your own key. An API key on its own returns only ciphertext — without your private key, no one (including open-banking.io) can make sense of it. The CLI and SDK only read and sync connections you already made in the dashboard; there is no connect command.

All of this runs for roughly EUR 3/month.

Both business and personal Deutsche Bank (Spain) accounts, under a single consent lasting up to 180 days.

Can open-banking.io read my Deutsche Bank data?
