When using the embedded SCA approach, which formats are used by the Sandboxes of the ASPSPs? Furthermore, which methods are supported during tests?
The Sandboxes of the ASPSPs support the same method and format as the productive system of the ASPSP supports.
There is no restriction and the Sandboxes deliver actual data in the correct format so that TPPs can test their functionality with genuine data.
However, these data are static.
