C24 Integration in Outbank

Setting up your C24 Account

  1. Open the Outbank app on iOS or Android device and go to ‘+NEW’ > ‘ Account’. In the macOS app, go to ‘Options’ > ‘Add Account’. This will launch the setup assistant of the app.

  2. Search for 'C24' in the list of supported banks. Select the bank from the search results and tap ‘Connect’.

  3. Perform 2-step-verification to synchronise your data.

How Does Two-Factor Authentication Work with C24?

Important: Please make sure you have version 3.48.0 or higher of the C24 Bank app installed.

With C24, you can choose between two verification methods, depending on whether Outbank and the C24 Bank app are installed on the same device or on different devices:

Via C24 Bank App:

If both apps are installed on the same device, you will be forwarded directly to C24 Bank app to read out the 6-digit-verification-code.

Via QR Code:

  1. If Outbank and the C24 Bank app are installed on different devices, a QR code will be displayed in the Outbank app.

  2. Open the C24 bank app on your other device. After logging in, tap ‘More’ at the bottom right, then ‘Online Banking’ at the top left (found under ‘Account Functions / My Account’).
    The in-app camera will launch to scan the QR code.
    If you receive a security notice saying “Never scan a QR code from a site other than banking.c24.de,” just tap ‘OK’.

  3. Scan the QR code from the Outbank app. C24 will generate a 6-digit TAN.

  4. Go back to the Outbank app and log in again. The authorization window with the QR code will still be visible.

  5. Enter the 6-digit TAN and confirm by tapping ‘OK’.

Each account refresh must be confirmed using two-factor authentication (2FA). To make the account refreshes more efficient, you can reduce the account refresh interval of N26 accounts. Additionally, you can group all C24 accounts in an account group. This way, only a single confirmation or TAN query is required for the entire group when updating all accounts.

Payments

As C24 currently does not provide any data through "HBCI+" or "FinTS PIN/TAN", Outbank fetches the data via screenscraping directly from the website, which means only balance and transaction queries are available. TAN-based transactions can only be supported once the bank enables the feature via "HBCI" or "FinTS PIN/TAN.'
