Create a course with a student. Create an assignment accepting only online text. Please remember the assignid since you'll need it later. As the student, add a submission with at least 1 embedded image or media. Enable "Mobile services": Plugins ► Web Services ► Mobile Create a Token for the student: 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, assignid and the URL of your moodle instance. curl 'http://localhost/m/stable_master/webservice/rest/server.php?moodlewsrestformat=json' --data 'assignid=2&wstoken=5b6154a56566a194f60f7f395f235179&wsfunction=mod_assign_get_submission_status&moodlewssettingfilter=true' 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. Check that the submission text is formatted (it's inside "lastattempt" > "submission" > "plugins" > "editorfields" > "text"). That is: URLs don't contain the wildcard "@@PLUGINFILE@@". If multimedia plugin is enabled and you added a video/audio, you receive an HTML5 player instead of a link to the file. Additionally, you can perform the request again but using moodlewssettingfilter=false&moodlewssettingfileurl=false and check that now the response isn't formatted.
