Moodle get course information + all lessons through Api

I am trying to collect all information related to Moodle course (course + lessons) Using Moodle Api I got the course information, but gets only some basic information, I want course details and its lessons (created under course) Eg : var domainname = 'http://<server URL>/moodle'; var token = 'df337369637c692303d903f8cacf1eb0'; var functionname = 'core_course_get_courses'; var serverurl = domainname + '/webservice/rest/server.php' ; var data = { wstoken: token, wsfunction: functionname, moodlewsrestformat: 'json' } var response = $.ajax( { type: 'GET', data: data, url: serverurl } ); And the output looks like {"id":2,"shortname":"IV Support Queries","categoryid":1,"categorysortorder":10001,"fullname":"IV Support Queries","displayname":"IV Support Queries","idnumber":"","summary":"<p>IV Support Queries Desc<br \/><\/p>","summaryformat":1,"format":"topics","showgrades":1,"newsitems":5,"startdate":1479168000,"numsections":5,"maxbytes":0,"showreports":0,"visible":1,"hiddensections":1,"groupmode":0,"groupmodeforce":0,"defaultgroupingid":0,"timecreated":1479127227,"timemodified":1479198758,"enablecompletion":0,"completionnotify":0,"lang":"","forcetheme":"","courseformatoptions":[{"name":"numsections","value":5},{"name":"hiddensections","value":1},{"name":"coursedisplay","value":1}]} I want the lesson details created under course .How can i get the information through Api .
