A Guardian resource represents a user, such as a parent, who receives information about a student's courses and coursework. The guardian, who typically isn't a member of the student's Classroom domain, must be invited using their email address.
Invitations are represented by the GuardianInvitation resource. The invited user receives an email prompting them to accept the invitation. If the email address is not associated with a Google Account, the user is prompted to create one before accepting the invitation.
When the user is invited and before they accept the invitation, the GuardianInvitation has a state of PENDING. Once the user accepts the invitation, the GuardianInvitation is marked as COMPLETED and a Guardian resource is created.
A GuardianInvitation state might also be changed to COMPLETED if it expires or if an authorized user cancels the invitation (for example, using the PatchGuardianInvitation method). A guardian relationship may also be broken by a guardian, a Classroom teacher, or an administrator, using either the Classroom web application or the DeleteGuardian method.

Common actions
This section describes some of the common guardian actions that you may want to perform using the Google Classroom API.
Create a guardian invitation
The following example shows how you can create a guardian invitation using the userProfiles.guardianInvitations.create() method:
Java
Python
guardianInvitation = { 'invitedEmailAddress': 'guardian@gmail.com', } guardianInvitation = service.userProfiles().guardianInvitations().create( studentId='student@mydomain.edu', body=guardianInvitation).execute() print("Invitation created with id: {0}".format(guardianInvitation.get('invitationId'))) The response includes a server-assigned identifier that can be used to refer to the GuardianInvitation.
Cancel a guardian invitation
To cancel an invitation, modify the state of the invitation from PENDING to COMPLETE by calling the userProfiles.guardianInvitations.patch() method. This is the only way to remove an invitation.
Java
Python
guardian_invite = { 'state': 'COMPLETE' } guardianInvitation = service.userProfiles().guardianInvitations().patch( studentId='student@mydomain.edu', invitationId=1234, # Replace with the invitation ID of the invitation you want to cancel updateMask='state', body=guardianInvitation).execute() List invitations for a specific student
You can get a list of all invitations that have been sent for a specific student using the userProfiles.guardianInvitations.list() method. By default, only PENDING invitations will be returned. A domain administrator can also retrieve invitations in the COMPLETED state by providing a states parameter.
Java
Python
guardian_invites = [] page_token = None while True: response = service.userProfiles().guardianInvitations().list( studentId='student@mydomain.edu').execute() guardian_invites.extend(response.get('guardian_invites', [])) page_token = response.get('nextPageToken', None) if not page_token: break if not courses: print('No guardians invited for this {0}.'.format(response.get('studentId'))) else: print('Guardian Invite:') for guardian in guardian_invites: print('An invite was sent to '.format(guardian.get('id'), guardian.get('guardianId'))) List active guardians
To determine which users are active guardians for a specific student, use the userProfiles.guardians.list() method. Active guardians are guardians who have accepted the invitation.
Java
Python
guardian_invites = [] page_token = None while True: response = service.userProfiles().guardians().list(studentId='student@mydomain.edu').execute() guardian_invites.extend(response.get('guardian_invites', [])) page_token = response.get('nextPageToken', None) if not page_token: break if not courses: print('No guardians invited for this {0}.'.format(response.get('studentId'))) else: print('Guardian Invite:') for guardian in guardian_invites: print('An invite was sent to '.format(guardian.get('id'), guardian.get('guardianId'))) Remove guardians
You can also remove a guardian from a student, using the userProfiles.guardians.delete() method:
Java
Python
service.userProfiles().guardians().delete(studentId='student@mydomain.edu', guardianId='guardian@gmail.com').execute()
