We're running 7.6.0 build 7600 in our test environment. I'm trying to use the API to allow technicians to pick up tickets. 

If I use the UpdateRequest operation, the "Assigned To" and "Group" fields in the ticket will not change. 

The API documentation mentions being able to pickup/assign tickets via the api but there no listing of the attributes for that. Is this documented anywhere or actually not supported?

Thanks
