List spaces

This guide explains how to use the list() method on the Space resource of the Google Chat API to list spaces. Listing spaces returns a paginated, filterable list of spaces.

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.

Listing spaces with app authentication lists spaces that the Chat app has access to. Listing spaces with User authentication lists spaces that the authenticated user has access to.

List spaces with user authentication

To list spaces in Google Chat, pass the following in your request:

The following example lists named spaces (but not group chats and direct messages, which are filtered out) visible to the authenticated user:

Node.js

chat/client-libraries/cloud/list-spaces-user-cred.js
import {createClientWithUserCredentials} from './authentication-utils.js';

const USER_AUTH_OAUTH_SCOPES = ['https://www.googleapis.com/auth/chat.spaces.readonly'];

// This sample shows how to list spaces with user credential
async function main() {
  // Create a client
  const chatClient = await createClientWithUserCredentials(USER_AUTH_OAUTH_SCOPES);

  // Initialize request argument(s)
  const request = {
    // Filter spaces by space type (SPACE or GROUP_CHAT or DIRECT_MESSAGE)
    filter: 'space_type = "SPACE"'
  };

  // Make the request
  const pageResult = chatClient.listSpacesAsync(request);

  // Handle the response. Iterating over pageResult will yield results and
  // resolve additional pages automatically.
  for await (const response of pageResult) {
    console.log(response);
  }
}

main().catch(console.error);

def list_spaces_with_user_cred():
    # Create a client
    client = create_client_with_user_credentials(SCOPES)

    # Initialize request argument(s)
    request = google_chat.ListSpacesRequest(
        # Filter spaces by space type (SPACE or GROUP_CHAT or DIRECT_MESSAGE)
        filter = 'space_type = "SPACE"',
        # Number of results that will be returned at once
        page_size = 100
    )

    # Make the request
    page_result = client.list_spaces(request)

    # Handle the response. Iterating over page_result will yield results and
    # resolve additional pages automatically.
    for response in page_result:
        print(response)

The Chat API returns a paginated list of spaces.

Customize pagination or filter the list

To list spaces in Google Chat, pass the following optional query parameters to customize pagination of or filter listed spaces:

  • pageSize: The maximum number of spaces to return. The service might return fewer than this value. If unspecified, at most 100 spaces are returned. The maximum value is 1,000; values higher than 1,000 are automatically changed to 1,000.
  • pageToken: A page token, received from a previous list spaces call. Provide this token to retrieve the subsequent page. When paginating, the filter value should match the call that provided the page token. Passing a different value might lead to unexpected results.
  • filter: A query filter. For supported query details, see the ListSpacesRequest reference.
