We want to integrate Turnitin with our custom built LMS. We already use Tunitin as offline mode .i.e upload the assignments to Turnitin and download the result. Now we want to integrate so that without uploading the Turnitin should check the contents captured by the students in our LMS and check the plagarism and provide the report. Please advise how this can be achieved. Where will we get the API keys and other details.
