Eurocity Bank API Access & Open Banking Integration

Reaching your Eurocity Bank account data no longer means wrestling with certificates, sandbox registrations, or a bespoke PSD2 client. open-banking.io gives you a single, certificate-free path to Eurocity Bank AG (BIC DLGHDEB1XXX) covering both business and personal accounts. The service spans 2,600+ EU and UK banks, and every balance and transaction that syncs is encrypted so that only you — never open-banking.io's servers — can read it.

The defining trait here is zero-knowledge design. When you sign up, an encryption key pair is generated locally on your own device from a passphrase you choose. open-banking.io stores only your public key, so the data it holds for Eurocity Bank stays as ciphertext on its side and is decrypted on yours.

How to connect Eurocity Bank

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

1. Create an open-banking.io account and set your encryption passphrase; your keys are created on your device at this step.
2. In the dashboard, search for and select Eurocity Bank, then choose the account type — business or personal.
3. You're redirected to Eurocity Bank's own secure login, where you approve access under PSD2 consent (valid for up to 180 days before a straightforward re-approval).
4. Your Eurocity Bank accounts sync back into the dashboard, ready to view.

Because you approve directly on the bank's screen, your credentials are never seen or handled by open-banking.io.

Access your data

Once the connection exists, developers can optionally read it programmatically. 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 use the CLI (openbanking accounts, openbanking transactions, openbanking sync), an SDK, or the REST API. Requests authenticate with the X-Api-Key header, and each response is decrypted locally with your private key. An API key alone only ever returns ciphertext — without your key, the payload stays unreadable. The CLI and SDK read and sync existing connections; they never create one.

All of this runs from roughly EUR 3/month.

Do I need a PSD2 certificate for Eurocity Bank?

No. open-banking.io is certificate-free; you approve access on Eurocity Bank's own consent screen.

Can open-banking.io read my Eurocity Bank transactions?

No. It holds only your public key, so stored data stays encrypted and is decrypted solely on your device.

How long does Eurocity Bank access last?

Up to 180 days per consent, after which you re-approve on the bank's login page.
