PSD Bank Koblenz API Access & Open Banking

Reaching your PSD Bank Koblenz accounts programmatically usually means wrestling with PSD2 certificates and sandbox paperwork. open-banking.io removes that barrier: you link PSD Bank Koblenz (BIC GENODEF1P12) once through a guided dashboard, and your balances and transactions become available to you as encrypted data that only your own key can unlock. It covers both business and personal accounts, and no eIDAS certificate or bank developer programme is required on your side.

How to connect PSD Bank Koblenz

Connecting happens entirely in 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 cryptographic keys are generated locally on your own device, so open-banking.io never holds anything but your public key.
  2. In the dashboard, search for PSD Bank Koblenz and choose the account type you want to link — business or personal.
  3. You are redirected to PSD Bank Koblenz's own secure login and consent screen, where you approve access directly with the bank (standard PSD2 consent).
  4. Your approved accounts sync back into your dashboard. Consent lasts up to 180 days, after which you simply re-approve on the bank's screen.

Access your data

Once PSD Bank Koblenz is connected, reading the data programmatically is an optional developer step. From 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. Every request sends the X-Api-Key header, and each response is decrypted locally with your own key. The API key alone only ever returns ciphertext, because open-banking.io's servers cannot read or decrypt your data.

Do I need a PSD2 certificate for PSD Bank Koblenz?

No. open-banking.io is certificate-free — you approve access on the bank's consent screen, so there is no eIDAS certificate or licence to obtain yourself.

Can open-banking.io see my PSD Bank Koblenz transactions?

No. The service is zero-knowledge and holds only your public key. Data is decrypted on your device with a private key that never leaves it.

How much does it cost?

Around EUR 3 per month, covering PSD Bank Koblenz and 2,600+ other supported EU and UK banks.
