Get a membership

This guide explains how to get a membership with the Google Chat API. Getting a membership returns details about the membership. The response is an instance of the Member resource.

Authenticating with app authentication lets a Chat app get memberships from spaces that it has access to in Google Chat (for example, spaces it's a member of), but excludes Chat app memberships, including its own. Authenticating with user authentication returns memberships from spaces that the authenticated user has access to.

Prerequisites

Python

  • Python 3.6 or greater
  • The pip package management tool
  • The Google client libraries for Python. To install them, run the following command in your command-line interface:

    pip3 install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib oauth2client
    
  • A published Chat app. To create and publish a Chat app, see Build a Google Chat app.

  • Authorization configured for the Chat app. Getting a membership supports both of the following authentication methods:

Get a membership

To asynchronously get a membership in Google Chat, pass the following in your request:

  • With app authentication, specify the chat.bot authorization scope. With user authentication, specify the chat.memberships.readonly or chat.memberships authorization scope. As a best practice, choose the most restrictive scope that still allows your app to function.
  • Call the get method on the Member resource.
  • Pass the name of the membership to get. Obtain the membership name from the membership resource of Google Chat.

Here's how to get a membership with user authentication:

Python

  1. In your working directory, create a file named chat_membership_get.py.
  2. Include the following code in chat_membership_get.py:

    import os.path
    
    from google.auth.transport.requests import Request
    from google.oauth2.credentials import Credentials
    from google_auth_oauthlib.flow import InstalledAppFlow
    from googleapiclient.discovery import build
    from googleapiclient.errors import HttpError
    
    # Define your app's authorization scopes.
    # When modifying these scopes, delete the file token.json, if it exists.
    SCOPES = ["https://www.googleapis.com/auth/chat.memberships.readonly"]
    
    def main():
        '''
        Authenticates with Chat API via user credentials,
        then gets details about a specified membership.
        '''
    
        # Authenticate with Google Workspace
        # and get user authorization.
        flow = InstalledAppFlow.from_client_secrets_file(
                    'client_secrets.json', SCOPES)
        creds = flow.run_local_server()
    
        # Build a service endpoint for Chat API.
        chat = build('chat', 'v1', credentials=creds)
    
        # Use the service endpoint to call Chat API.
        result = chat.spaces().members().get(
    
            # The membership to get.
            #
            # Replace SPACE with a space name.
            # Obtain the space name from the spaces resource of Chat API,
            # or from a space's URL.
            #
            # Replace MEMBER with a membership name.
            # Obtain the membership name from the memberships resource of
            # Chat API.
            name='spaces/SPACE/members/MEMBER'
    
        ).execute()
    
        # Prints details about the created membership.
        print(result)
    
    if __name__ == '__main__':
        main()
    
  3. In the code, replace the following:

  4. In your working directory, build and run the sample:

    python3 chat_membership_get.py
    

The Chat API returns an instance of Member detailing the specified membership.
