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

Manage Courses

Stay organized with collections Save and categorize content based on your preferences.

A Course resource represents a class, such as "Math 127," and its assigned teachers, student roster, and metadata.

Each course is identified by a unique ID assigned by the server. Additionally, names may be associated with a course and used in place of the unique ID. Each name, called an Alias, exists in a namespace that restricts who can create and view it.

Two namespaces are supported:

  • Domain: The domain namespace is useful for creating aliases that all users need access to, but that are not specific to any one program. For example, alternate listings for a course, such as MATH 127 and COMSCI 127, should be created in the domain namespace. Aliases in the domain namespace may only be created by domain administrators but are visible to all users in a domain.
  • Developer project: The developer project namespace is useful for managing aliases specific to an application. For example, an application that uses alternate identifiers for courses can create aliases to map its identifier to Classroom courses. Aliases created in this namespace are tied to a specific Google API Console project. Any user of an application can create and view aliases in the namespace for that application's developer project.

Create a course

You can add a course using the courses.create() method, as shown in the following sample:

When you create a course, you can optionally add metadata such as the course description, time, or location.

In order to create a course, the user making the request must have the appropriate permissions in their user profile.

Courses are created with the courseState set to PROVISIONED by default; however, this can be overridden to ACTIVE. If the course is created in the PROVISIONED state, the teacher identified in the ownerId must accept the class in the Classroom UI or the course must be updated through the API to change the courseState to ACTIVE and make it available to their students.

Retrieve course details

You can retrieve a single course's metadata with the courses.get() method, as shown in the following sample:

You can also list only the courses for a specific user. For more information, see Retrieve courses for a user.

Update course information

You can update some course metadata after the course is created. The following fields can be updated any time after the course is created:

  • name
  • section
  • descriptionHeading
  • description
  • room
  • courseState
  • ownerId

To update all fields in a course, use the courses.update() method, as shown in the following sample:
