You need to replace the wstoken, attemptid and the URL of your moodle instance curl 'http://localhost/m/stable_master/webservice/rest/server.php?moodlewsrestformat=json' --data 'attemptid=2&wsfunction=mod_quiz_view_attempt&wstoken=ffbe3a3002f235bf9d01fd9369e10b66&page=0&preflightdata%5B0%5D%5Bname%5D=quizpassword&preflightdata%5B0%5D%5Bvalue%5D=abc'' Confirm that You can see new entries in the course log (quiz attempt viewed) for that course and the user. The origin for the new log entries is "ws" If you use an incorrect password, you see an error as the ws response Now, execute the same curl request but removing &page=0 and replacing, mod_quiz_view_attempt with mod_quiz_view_attempt_summary Check that there is a new entry in the course log (quiz attempt summary viewed) with origin "ws"
