Hello Roger,
If you do not mind, would you be able to raise a Support case for this one please, and hit me up with the case # on the same?
I don't think we have the needed support (in REST) for something like a CGI_URL in regular SDM UI where the resulting data sets are masked for you by the CGI_URL.
However, I'd like to get this passed by our engineering team.
Thx
