By default a new created transaction/consent has the status “received”. In order to perform SCA using REDIRECT approach, the sandbox provides a Redirect Server where the status gets updated depending on the PSU.

The Query Parameter psu-id is mandatory. If it is not provided, the Redirect Server will display a default error message.
