I've been trying to identify what is the correct way to get data from Project Online for some time now (I just want to get data, not update it). I can find documentation on ProjectData and a lot of examples using it. But it requires permission edition on the Project Online configuration.
I Barely can find any example or documentation for the ProjectServer and its endpoints seem to have fewer options than ProjectData.
Which one should be used to GET info from the ProjectOnline and why?
