I have tried using various methods for using PUT to update "otherGroups" with no success. It doesn't appear that the GROUP object allows for modifying members either.
I have been trying to add otherGroups using the
https://company.attask-ondemand.com/attask/api-internal/user? link, specifying user id and apiKey, posting JSON with {"otherGroups": [{"ID", ID}, {"ID", ID}]} or similar.
No error is returning from Workfront, I'm just getting a status: 200. I am trying to get "default" groups added to each user that is newly added to the system.
