Groups API

Groups serve as the data for a few different ideas in Canvas. The first is that they can be a community in the canvas network. The second is that they can be organized by students in a course, for study or communication (but not grading). The third is that they can be organized by teachers or account administrators for the purpose of projects, assignments, and grading. This last kind of group is always part of a group category, which adds the restriction that a user may only be a member of one group per category.

All of these types of groups function similarly, and can be the parent context for many other types of functionality and interaction, such as collections, discussions, wikis, and shared files.

Group memberships are the objects that tie users and groups together.

A Group object looks like:

{
  // The ID of the group.
  "id": 17,
  // The display name of the group.
  "name": "Math Group 1",
  // A description of the group. This is plain text.
  "description": null,
  // Whether or not the group is public.  Currently only community groups can be
  // made public.  Also, once a group has been set to public, it cannot be changed
  // back to private.
  "is_public": false,
  // Whether or not the current user is following this group.
  "followed_by_user": false,
  // How people are allowed to join the group.  For all groups except for
  // community groups, the user must share the group's parent course or account. 
  // For student organized or community groups, where a user can be a member of as
  // many or few as they want, the applicable levels are
  // 'parent_context_auto_join', 'parent_context_request', and 'invitation_only'. 
  // For class groups, where students are divided up and should only be part of
  // one group of the category, this value will always be 'invitation_only', and
  // is not relevant. * If 'parent_context_auto_join', anyone can join and will be
  // automatically accepted. * If 'parent_context_request', anyone  can request to
  // join, which must be approved by a group moderator. * If 'invitation_only',
  // only those how have received an invitation my join the group, by accepting
  // that invitation.
  "join_level": "invitation_only",
  // The number of members currently in the group
  "members_count": 0,
  // The url of the group's avatar
  "avatar_url": "https://<canvas>/files/avatar_image.png",
  // The course or account that the group belongs to. The pattern here is that
  // whatever the context_type is, there will be an _id field named after that
  // type. So if instead context_type was 'account', the course_id field would be
  // replaced by an account_id field.
  "context_type": "Course",
  // The course or account name that the group belongs to.
  "context_name": "Course 101",
  "course_id": 3,
  // Certain types of groups have special role designations. Currently, these
  // include: 'communities', 'student_organized', and 'imported'. Regular
  // course/account groups have a role of null.
  "role": null,
  // The ID of the group's category.
  "group_category_id": 4,
  // The SIS ID of the group. Only included if the user has permission to view SIS
  // information.
  "sis_group_id": "group4a",
  // The id of the SIS import if created through SIS. Only included if the user
  // has permission to manage SIS information.
  "sis_import_id": 14,
  // the storage quota for the group, in megabytes
  "storage_quota_mb": 50,
  // optional: the permissions the user has for the group. returned only for a
  // single group and include[]=permissions
  "permissions": {"create_discussion_topic":true,"create_announcement":true},
  // optional: A list of users that are members in the group. Returned only if
  // include[]=users. WARNING: this collection's size is capped (if there are an
  // extremely large number of users in the group (thousands) not all of them will
  // be returned). If you need to capture all the users in a group with certainty
  // or experiencing slow response consider using the paginated
  // /api/v1/groups/<group_id>/users endpoint.
  "users": null,
  // Indicates whether this group category is non-collaborative. A value of true
  // means these group categories rely on the manage_tags permissions and do not
  // have collaborative features
  "non_collaborative": null
}

A GroupMembership object looks like:

{
  // The id of the membership object
  "id": 92,
  // The id of the group object to which the membership belongs
  "group_id": 17,
  // The id of the user object to which the membership belongs
  "user_id": 3,
  // The current state of the membership. Current possible values are 'accepted',
  // 'invited', and 'requested'
  "workflow_state": "accepted",
  // Whether or not the user is a moderator of the group (the must also be an
  // active member of the group to moderate)
  "moderator": true,
  // optional: whether or not the record was just created on a create call (POST),
  // i.e. was the user just added to the group, or was the user already a member
  "just_created": true,
  // The id of the SIS import if created through SIS. Only included if the user
  // has permission to manage SIS information.
  "sis_import_id": 4
}

Use the course-wide option with the following parameters: - `all_in_group_course` [Boolean]: If set to true, the endpoint will add every currently enrolled student (from the course context) to the differentiation tag. - `exclude_user_ids[]` [Integer]: When using `all_in_group_course`, you can optionally exclude specific users by providing their IDs in this parameter. In this context, these parameters only apply to differentiation tag memberships.

Parameter	Type	Description
user_id	string	- The ID of the user for individual membership creation.
members[]	integer	- Bulk add multiple users to a differentiation tag.
all_in_group_course	boolean	- If true, add all enrolled students from the course.
