Get details about a space

This guide explains how to use the get method on a Space resource of the Google Chat API to see details about a space, like its display name, description, and guidelines.

The Space resource represents a place where people and Chat apps can send messages, share files, and collaborate. There are several types of spaces:

  • Direct messages (DMs) are conversations between two users or a user and a Chat app.
  • Group chats are conversations between three or more users and Chat apps.
  • Named spaces are persistent places where people send messages, share files, and collaborate.

Authenticating with app authentication lets a Chat app get spaces that the Chat app has access to in Google Chat (for example, spaces that the app is a member of). Authenticating with user authentication lets you get spaces that the authenticated user has access to.

Prerequisites

Python

  • Python 3.6 or greater
  • The pip package management tool

  • The latest Google client libraries for Python. To install or update them, run the following command in your command-line interface:

    pip3 install --upgrade google-api-python-client google-auth-oauthlib google-auth
  • A Google Cloud project with the Google Chat API enabled and configured. For steps, see Build a Google Chat app.

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

Node.js

  • Node.js & npm

  • The latest Google client libraries for Node.js. To install them, run the following command in your command-line interface:

    npm install @google-cloud/local-auth @googleapis/chat
  • A Google Cloud project with the Google Chat API enabled and configured. For steps, see Build a Google Chat app.

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

Get a space

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

  • With app authentication, specify the chat.bot authorization scope. With user authentication, specify the chat.spaces.readonly or chat.spaces authorization scope.
  • Call the get method on the Space resource, passing the name of the space to get. Obtain the space name from the spaces resource of Google Chat, or from a space's URL.

Get space details with user authentication

Here's how to get space details with user authentication:

Python

  1. In your working directory, create a file named chat_space_get_user.py.

  2. Include the following code in chat_space_get_user.py:

    from google_auth_oauthlib.flow import InstalledAppFlow
from googleapiclient.discovery import build

# 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.spaces.readonly"]

def main():
    '''
    Authenticates with Chat API via user credentials,
    then gets details about a specified space.
    '''

    # 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().get(

          # The space 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.
          name='spaces/SPACE'

      ).execute()

    # Prints details about the space.
    print(result)

if __name__ == '__main__':
    main()

  3. In the code, replace SPACE with a space name, which you can obtain from the spaces.list method in the Chat API, or from a space's URL.

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

    python3 chat_space_get_user.py

Node.js

  1. In your working directory, create a file named get-space.js.

  2. Include the following code in get-space.js:

    const chat = require('@googleapis/chat');
const {authenticate} = require('@google-cloud/local-auth');

/**
* Gets details about a Chat space by name.
* @return {!Object}
*/
async function getSpace() {
  const scopes = [
    'https://www.googleapis.com/auth/chat.spaces.readonly',
  ];

  const authClient =
      await authenticate({scopes, keyfilePath: 'client_secrets.json'});

  const chatClient = await chat.chat({version: 'v1', auth: authClient});

  return await chatClient.spaces.get({name: 'spaces/SPACE'});
}

getSpace().then(console.log);

  3. In the code, replace SPACE with a space name, which you can obtain from the spaces.list method in the Chat API, or from a space's URL.

  4. In your working directory, run the sample:

    node get-space.js

The Chat API returns an instance of Space that details the specified space.

Get space details with app authentication

Here's how to get space details with app authentication:

Python

  1. In your working directory, create a file named chat_space_get_app.py.

  2. Include the following code in chat_space_get_app.py:

    from google.oauth2 import service_account
from apiclient.discovery import build

# Specify required scopes.
SCOPES = ['https://www.googleapis.com/auth/chat.bot']

# Specify service account details.
CREDENTIALS = (
    service_account.Credentials.from_service_account_file('credentials.json')
    .with_scopes(SCOPES)
)

# Build the URI and authenticate with the service account.
chat = build('chat', 'v1', credentials=CREDENTIALS)

# Use the service endpoint to call Chat API.
result = chat.spaces().get(

    # The space 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.
    name='spaces/SPACE'

).execute()

print(result)

  3. In the code, replace SPACE with a space name, which you can obtain from the spaces.list() method in the Chat API, or from a space's URL.

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

    python3 chat_space_get_app.py

Node.js

  1. In your working directory, create a file named app-get-space.js.

  2. Include the following code in app-get-space.js:

    const chat = require('@googleapis/chat');

/**
* Gets details about a Chat space by name.
* @return {!Promise<!Object>}
*/
async function getSpace() {
  const scopes = [
    'https://www.googleapis.com/auth/chat.bot',
  ];

  const auth = new chat.auth.GoogleAuth({
    scopes,
    keyFilename: 'credentials.json',
  });

  const authClient = await auth.getClient();
  const chatClient = await chat.chat({version: 'v1', auth: authClient});

  return await chatClient.spaces.get({name: 'spaces/SPACE'});
}

getSpace().then(console.log);

  3. In the code, replace SPACE with a space name, which you can obtain from the spaces.list method in the Chat API, or from a space's URL.

  4. In your working directory, run the sample:

    node app-get-space.js

The Chat API returns an instance of Space that details the specified space.
