Help needed to assign a list of users for a course
Hi Charlie,
I am unable to go beyond the code mentioned below

litmos = Litmos({'aXXXXXXXXXXXXX'},{'https://api.litmoseu.com/v1.svc'})

Is there anyway I could directly get the Json file downloaded. Or derive a code to assign course to a list of users 

Thanks in advance.

Regards,
Jins
