In a course create a lesson with at least one content page and one question page, and with the Appearance -> Progress bar value set to Yes. Enrol one user as student in the course where the lesson is. As student access to the lesson (just view the first pageid) As admin, enable "Mobile services": Site administration ► Mobile app ► Mobile settings 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), pageid with the lesson first page id and the URL of your moodle instance curl 'http://localhost/m/stable_master/webservice/rest/server.php?moodlewsrestformat=json' --data 'lessonid=13&pageid=96&returncontents=1&wsfunction=mod_lesson_get_page_data&wstoken=12a2a65aeea2a177055e233f9e303218&moodlewssettingfilter=true' | python -m "json.tool" Confirm that you receive all the page information, including title and contents, you receive also the pagecontents that matches the Moodle rendered content for the page. Check if that you progress in the lesson via the web interface, the progress field is update in further curl requests.
