Hello, I'm trying to integrate our Student Records data into Canvas using the API and have come across a problem with the sis_user_id.
Basically if a student withdraws for a course we will delete the user from Canvas but if they join again later on another or same course then they will get added back into Canvas but have the same sis_user_id as its mapped the Unique Student.
When I try and do this I get the following error:
attribute=sis_user_id
message=SIS ID "21021960" is already in use
type=SIS ID "21021960" is already in use
Any ideas on how to overcome this?
