Note: Version numbers are bumped because a new web service is added into the Mobile app service and also in a module. Create a course with a teacher and a student. Create a sample scorm activity, you should use the singlescobasic.zip found here https://github.com/moodle/moodle/tree/master/mod/scorm/tests/packages . As the student, access the scorm package and start a couple of attempts (don't forget to select the start new attempt option). Enable "Mobile services": Plugins ► Web Services ► Mobile Create a Token for the teacher and the student: Click on Site administration ► Plugins ► Web services ► Manage tokens Next, you can do a couple of CURL REST call simulating a WS client with the student user . You need to replace the wstoken, scoid (scorm_scoes table id), userid and the URL of your moodle instance. Do two requests using attempt=1 and attempt=2 curl 'http://localhost/m/stable_master/webservice/rest/server.php?moodlewsrestformat=json' --data 'scoid=2&userid=3&attempt=1&wsfunction=mod_scorm_get_scorm_sco_tracks&wstoken=ffbe3a3002f235bf9d01fd9369e10b66' Note, you can use jsonlint.com to validate and format the json returned string or append "| python -m json.tool" to automatically format the command output Confirm that You receive as response an array containing all the sco data for the specified attempt You should compare the data you received with the SCORM data report that you can see as a teacher in the report tab of mod/scorm/view.php (click in the attempt number and then in track details) you will see some SCORM variables like cmi.core.lesson_status Try to retrieve the track information for other existing userid, you should see a required_capability_exception Using the teacher token execute the same curl command, the output should be the same
