Currently Wonde is offering both the Wonde instant set-up of classes and SSO as a package. This means that in order to use the SSO though Wonde your classes would first need to be set-up and shared with Sumdog through Wonde's secure sync.
Here is more information on how you can get started having your classes set-up instantly through Wonde.
If you have any questions do contact us at firstname.lastname@example.org.
Note: To access Sumdog through Wonde your school would first need to share your school data with Sumdog through Wonde's secure sync.
