Hello,
I am attempting to initiate an endpoint operation via the management api using postman:

I receive the above error "InvalidParameter" for a parameter called "operations". I am not sure where this is located in the enumerations for this URL, but I am having some trouble getting over this bump. Is it referring to the URL, if so, how do I resolve this issue? I would like to build a script to initiate operations like these if endpoints meet a specified criteria. I am new to API development work, but I have been able to figure out most of the documentation. I am performing the POST method exactly how I would to receive the Auth token. Any thoughts?
Thanks
