In order to authenticate using Classlink (Single Sign On), the configuration must be added within both Visitor Aware, and your Classlink developer portal.
Much like when configuring the Classlink SIS sync with Visitor Aware... within Classlink you will need to have the Visitor Aware App installed and Enabled.
You will need to gather the following from your Classlink Instance:
- Client / Application ID *
- Client Secret / Access Token *
- OneRoster Endpoint * ( Should end in "/ims/oneroster/v1p1" )
- Tenant ID *
Then take those Classlink credentials and populate them in Visitor Aware:
