I used Forge API to post projects in BI360, now I am trying to add few users using the data frame of the projects created. According to the Forge Documentation you can post users to one project, looking for  an advise how to post users to several projects
TIA
I checked, and all endpoints take only one project id, so you have to loop through multiple projects and add the user(s) to all projects, currently not possible in one call.
Batch add users to BIM360
