I have a SP workflow that creates a new project subsite upon a new project being created in the master list but cannot see how to break the permissions inheritance from the Parent site.
Each project subsite is required to have a specific user group access requirement in addition to others that can view all subsites. I have found multiple sources of how to break / set permissions for Items eg lists, document libraries and documents but not how to control the sub site itself.
I assume it will be some form REST api command but cannot figure it out. Any help gratefully received
