In a course create a lesson with at least one content page. Enrol one user as student in the course where the lesson is. Attempt the lesson as the student a couple of times. Be sure that you finished the lesson at least once. As admin, enable "Mobile services": Plugins ► Web Services ► Mobile Create a Token for the student user Click on Site administration ► Plugins ► Web services ► Manage tokens Next, you can do a CURL REST call simulating a WS client with the student user . You need to replace the wstoken, lessonid (the lesson instance value) and the URL of your moodle instance curl 'http://localhost/m/stable_master/webservice/rest/server.php?moodlewsrestformat=json' --data 'lessonid=5&wsfunction=mod_lesson_get_user_timers&wstoken=12a2a65aeea2a177055e233f9e303218&moodlewssettingfilter=true' | python -m "json.tool" Confirm that you receive correctly the two timers, the first one should be marked as completed Now, create a token for a teacher in the course and execute again the curl request appending: &userid=X (X is the id of the student user who attempted the lesson) Confirm that you receive correctly the list of timers.
