Get Line Items

The Assignment & Grades endpoint tools call to list grade lines in a context. You never call this — LTIAAS relays it to your Service URL as a LINEITEMS_GET service request.

Path Parameters

contextId string required
The URL-encoded context identifier — the same context value you supplied when starting the launch.
Example: 2022CSEa5e6c431b91
