I am able to publish to a default site using command line. Do we have option to publish Prep to a particular Project within default site? All I see as from the following link is few commends we can use.
|Input connections||Output location|
Do we have a parameter in JSON file to Project?
I published to a project not within the default site. So, i guess you can publish to a particular project within the default site.
The parameter within the JSON file to specify a site is "contentUrl"
