POST URL call for incomplete transactions
During the SOFORT Banking payment process it is possible that the customer closes his browser window too early or at the wrong moment. In order to prevent potential inconsistencies we recommend activating the checkbox 'Send Post data with uncomplete' within the Datatrans Webadmin Tool under UPP Administration -> UPP Data. This ensures that your POST URL is called in the event of an incomplete transaction.
