I am building a tool for an LMS.

At some point, users finish courses and the tool is expected to send a grade to the LMS.

The url to which this grade must be pushed comes from the LMS.

However, what happens when a tool offers multiple courses?

A user would click on a course in the LMS, which comes with the lineItem url to which to push its grades, and then finish a different course.

How can the tool know to which url push a grade in this case?
