Google Classroom Batching

[Clay Smith]

Hi All, I'm attempting to "create" students to a classroom with a batch request. I get returned "Not found" as the error. Has anyone been able to make this work?

Thanks, 

Clay

//emails is an array of email. courseid is the classroom id

function(emails, courseid){
  for(var i=0;i<emails.length;i++){

    var studentResource = {

                userId: emails[i]

            }

    var classResource = {

      method: 'POST',

      endpoint: 'https://classroom.googleapis.com/v1/courses/'+courseid+'/students',

      requestBody: studentResource

    }

    body.push(classResource)

  }
  var response=  batch(body,"https://www.googleapis.com/batch/classroom/v1");
}


//batch function with exp backoff
function batch(body, url) {

  if(body.length<1){

    return []

  var contentId = 0;

  var data = '--' + boundary + '\r\n';
