Credit card

Current test credit cards, with and without 3D Secure, can be found directly in the Wirecard developer documentation.

SEPA Direct Debit

IBAN DE42512308000000060004


5. Limitations

- Direct debit payments can only be made in euro as the currency

6. Account reconciliation

If you use Wirecard as a payment service provider, Wirecard will automatically inform you about returned direct debits via a matching import. If you use Wirecard's new API Elastic Engine, you will also be automatically informed about credit card chargebacks via the reconciliation import.

billwerk retrieves the reconciliation files daily from the Wirecard SFTP server, reads them in and the information they contain is assigned to the corresponding contract accounts and booked.

Problems when importing the reconciliation file

If the adjustment file could not be read in automatically, the most common cause is an expired password for accessing the Wirecard SFTP server. Please contact your Wirecard account manager or directly the Wirecard support and have the password reset. Now assign a new password in Wirecard and save the new password in your billwerk payment settings. To do so, go to "Settings > Payment > Payment settings > Wirecard", click on the "Edit" button and store your new password in the "Reconciliation import" area.


The next time the files are regularly retrieved the next morning, all files not yet downloaded will now be retrieved and read into billwerk.abgleichsimport2.png
