Manage Courses

A Course resource represents a class, such as "MATH 127". It includes fields such as name, ownerId, and courseState. The Course resource is the parent resource of many other Classroom API resources.

Create a course

You can create a course using the courses.create() method. When you create a course, some fields such as the name and ownerId are required. You can optionally add metadata such as the description, section, or room.

Each course is assigned a unique ID by Classroom. Courses may also be referenced using an alias. See the manage aliases guide for information on adding project-scoped and domain-scoped aliases to courses.

The following pointers are helpful to keep in mind when creating courses using the Classroom API:

  • Create an alias by setting the course id field:

    • It's recommended that you add an alias to the course. When creating a Course, you can specify the alias within the id field. This automatically creates an alias for the course. You can also add an alias for a course using the courses.aliases.create() method.
    • Keep in mind that when reading course data using the courses.get() or courses.list() method, the id field returns the Classroom-assigned ID. You can retrieve a list of aliases for a course by making a request to the courses.aliases.list() method.
  • Only domain administrators can create courses on behalf of other users in their domain: Any other user receives a 403 error if specifying a user other than themselves in the ownerId field.

  • If the courseState field isn't specified, it is set to PROVISIONED by default: If the course is in the PROVISIONED state, the teacher identified in the ownerId field must accept the class in the Classroom UI or the course must be updated through the API to change the courseState to ACTIVE. ACTIVE courses are available to students.

  • Consumer accounts (*@gmail.com) cannot create courses in the ACTIVE state: Requests to do so return a 403: PERMISSION_DENIED error.

The following sample makes a request to the courses.create() method:

Update course information

The Classroom API lets you update some course metadata after the course is created. Updating course information can be important when managing deleted users in a domain. For example, if a domain administrator must delete a teacher's account in the Google Admin console, they should transfer ownership of the course before doing so. This minimizes the risk of losing access to the course.

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:

Update the course owner

Domain administrators can use the courses.patch() method to update the ownerId field and transfer ownership of a course to a new teacher within their domain. If the new teacher is not already a co-teacher, make a request to the teachers.create() method to add them to the course before updating the ownerId field.
