PLEASE NOTE: ClassLink setup with SFTP is not used for new customers. This information is provided for legacy customers who have not moved to API setup at this time.
To use SFTP upload with ClassLink and ST Math, you must complete the setup as shared on the ST Math + ClassLink OneRoster API Setup article and then set up SFTP access.
To do this, click on Applications, go to Settings, More Actions
Then go to File Exports and enter the sftp credentials provided to you by ST Math and Save.
Then you will need to enable the sync to set the schedule so that information is automatically shared with ST Math.
As long as the credentials are accurate, ST Math will get the data to the sftp server.
