Lightning Grader API
See an example integration with the Lightning Grader API for generating
and grading Assignment PDFs, via the RESTful JSON API.
Important Usage Notes:
At this time the camera grader plugin will only work with Google Chrome. Please
make sure you are using Chrome if you are testing this feature.
Viewing JSON will be much easier if you have a JSON formatting plugin installed
in your browser, such as
the one at this here link.
