SDK, Trying to call Members from Group Gmail and Update

Question

I am trying to create a call that gets all the group Gmail emails so that I can update those that aren't there and delete those that shouldn't be. I am currently trying the below code and I'm getting a scope error.

# If modifying these scopes, delete the file token.json.
SCOPES = ['https://www.googleapis.com/auth/admin.directory.group.members', 'https://www.googleapis.com/auth/admin.directory.group']

def main():
    """Shows basic usage of the Admin SDK Directory API.
    Prints the emails and names of the first 10 users in the domain.
    """
    creds = None
    # The file token.json stores the user's access and refresh tokens, and is
    # created automatically when the authorization flow completes for the first
# time.
    if os.path.exists('token.json'):
        creds = Credentials.from_authorized_user_file('token.json', SCOPES)
# If there are no (valid) credentials available, let the user log in.
    if not creds or not creds.valid:
        if creds and creds.expired and creds.refresh_token:
           creds.refresh(Request())
        else:
            flow = InstalledAppFlow.from_client_secrets_file(
            'credentials.json', SCOPES)
            creds = flow.run_local_server(port=0)
    # Save the credentials for the next run
        with open('token.json', 'w') as token:
            token.write(creds.to_json())

    service = build('admin', 'directory_v1', credentials=creds)

 # Call the Admin SDK Directory API
    print('Getting the members of Hospitality Team')
    response_group = service.groups().list(customer='my_customer').execute()
    for group in response_group['groups']:
       print(group['email'])

Solution:

You could do the following:

• List all your groups via Groups: list.
• For each group, check whether it has members.
• If the group has members, retrieve its members via Members: list.
• For each desired member coming from the other API, check if it already exists in the group. If it doesn't exist, add it to your group via Members: insert.
• For each current member in the group, check if it's one of the desired members. If it's not, delete it via Members: delete.
• If the group does not have members, add all desired members to the group via Members: insert.

Code snippet:

def updateGroupMembers(service):
    ideal_member_emails = ["member_1@example.com", "member_2@example.com", "member_3@example.com"]
    response_group = service.groups().list(customer='my_customer').execute()
    for group in response_group['groups']:
        group_email = group['email']
        response_members = service.members().list(groupKey=group_email).execute()
        if "members" in response_members:
            current_member_emails = list(map((lambda member : member["email"]), response_members["members"]))
            for ideal_member_email in ideal_member_emails:
                if ideal_member_email not in current_member_emails:
                    payload = {
                        "email": ideal_member_email
                    }
                    service.members().insert(groupKey=group_email, body=payload).execute()
            for current_member_email in current_member_emails:
                if current_member_email not in ideal_member_emails:
                    service.members().delete(groupKey=group_email, memberKey=current_member_email).execute()
        else:
            for ideal_member_email in ideal_member_emails:
                payload = {
                    "email": ideal_member_email
                }
                service.members().insert(groupKey=group_email, body=payload).execute()

Notes:

• The scopes you are providing should be enough for these calls. If you edited those scopes after last authenticating, remove the old token.json and authenticate again.
• Make sure the authenticated user has edit access to these groups.
• Here I'm assuming the desired list of members is the same for all groups. I'm also assuming you have a list of these emails (currently ideal_member_emails). If that's not the case, please edit the provided script according to your preferences.
• If your list of groups and members is large enough, you should iteratively fetch the different page results for your list requests. See this related answer (regarding Users: list, but the process is identical) for more information on how to do this.
