Consorsbank API Access & Open Banking Made Simple

Consorsbank is a German online bank and brokerage known for low-cost investing and everyday personal banking. If you want your Consorsbank balances and transactions in one place, or feeding a budgeting app, spreadsheet, or script, open-banking.io gives you a certificate-free path to your own data across the EU and UK.

There is no TPP licence to obtain and no eIDAS certificate to buy. You keep control because your Consorsbank data is decrypted on your own device with a key that never leaves it. open-banking.io covers 2,600+ banks and costs around EUR 3 per month.

How to connect Consorsbank

Connecting happens entirely inside the open-banking.io dashboard, not through any API call or code:

  1. Sign up for open-banking.io and set your encryption passphrase. Your key pair is generated locally on your device, so only you hold the private key.
  2. In the dashboard, search for Consorsbank (BIC CSDBDE71) and choose the personal account type.
  3. You are redirected to Consorsbank’s own secure login to approve access under PSD2. Consent lasts up to 180 days, after which you simply reauthorise.
  4. Your accounts sync back into your dashboard, ready to view.

No API key, credential, or developer redirect is used to connect — the bank’s own consent screen does the authorisation.

Access your data

Reading Consorsbank data programmatically is an optional step you take after connecting. Open the Developers page, create an API key, and export a credentials.json file. It bundles the API key with your private decryption key, so responses can be unlocked on your machine.

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 payload is decrypted locally. The CLI and SDK only read and refresh connections you already made in the dashboard — there is no connect command.

Because open-banking.io is zero-knowledge, its servers hold only your public key. Without your private key, an API key alone returns ciphertext, so no one but you can read your Consorsbank statements.

Does open-banking.io need a banking certificate?

No. It is certificate-free — no eIDAS or TPP licence. You authorise access directly on Consorsbank’s login screen.

Can open-banking.io see my transactions?

No. Data is encrypted with your key and decrypted only on your device. The service stores nothing readable.

How long does access last?

Consorsbank consent runs up to 180 days. When it expires, reconnect from the dashboard in a few clicks.
