Are your users using Classroom with Google Meet? Check out the Apps Script quickstart covering how to check student attendance in Google Meet courses.

Google Apps Script quickstart

Quickstarts explain how to set up and run an app that calls a Google Workspace API.

Google Workspace quickstarts use the API client libraries to handle some details of the authentication and authorization flow. We recommend that you use the client libraries for your own apps. This quickstart uses a simplified authentication approach that is appropriate for a testing environment. For a production environment, we recommend learning about authentication and authorization before choosing the access credentials that are appropriate for your app.

Create a Google Apps Script that makes requests to the Google Classroom API.

Objectives

  • Create the script.
  • Enable the Google Classroom API.
  • Run the sample.

Prerequisites

  • A Google for Education account with Google Classroom enabled.

  • Access to Google Drive

Create the script

  1. Create a new script by going to script.google.com/create.
  2. Replace the contents of the script editor with the following code:

classroom/quickstart/quickstart.gs
/**
 * Lists 10 course names and ids.
 */
function listCourses() {
  /**  here pass pageSize Query parameter as argument to get maximum number of result
   * @see https://developers.google.com/classroom/reference/rest/v1/courses/list
   */
  const optionalArgs = {
    pageSize: 10
    // Use other parameter here if needed
  };
  try {
    // call courses.list() method to list the courses in classroom
    const response = Classroom.Courses.list(optionalArgs);
    const courses = response.courses;
    if (!courses || courses.length === 0) {
      console.log('No courses found.');
      return;
    }
    // Print the course names and IDs of the courses
    for (const course of courses) {
      console.log('%s (%s)', course.name, course.id);
    }
  } catch (err) {
    // TODO (developer)- Handle Courses.list() exception from Classroom API
    // get errors like PERMISSION_DENIED/INVALID_ARGUMENT/NOT_FOUND
    console.log('Failed with error %s', err.message);
  }
}
