As admin, enable "Mobile services": Site administration ► Mobile app ► Mobile settings Create a Token in the mobile app service for one user enrolled in a course: Click on Site administration ► Plugins ► Web services ► Manage tokens Next, you can do a CURL REST call simulating a WS client with the user. You need to replace the wstoken, and the URL of your moodle instance curl 'http://localhost/m/stable_master/webservice/rest/server.php?moodlewsrestformat=json' --data 'contexts [0] [contextlevel] =coursecat&contexts [0] [instanceid] =1&wsfunction=core_filters_get_available_in_context&wstoken=12a2a65aeea2a177055e233f9e303218' | python -m "json.tool" Now, go to your category with id 1 in Moodle: http://localhost/m/stable_master/course/index.php?categoryid=1 Via the settings menu (gear) go to the Filter section and check that all the filters listed in that page are returned by the curl request You may also check that the localstate field from the curl request for every filter is 0 when the filter "Active" status in web is set to "Default", 1 when is set to "On" and -1 when set to "Off" Now, execute the same request but at course level: replace the contextlevel field that is set to coursecat with course, and the instanceid to the course id you are going to check Check again that you receive all the filters that are listed in the course filters page (accesible via the course page settings) and that the "Active" status is set to the correct values (as indicated in step 6) Do the same checks for a course module, in this case replace contextlevel to module and instanceid with the module cmid
