List members in a space

This guide explains how to use the list() method on the Membership resource of the Google Chat API to list members in a space as a paginated, filterable list of memberships in a space.

  • Listing memberships with app authentication lists memberships in spaces that the Chat app has access to, but excludes Chat app memberships, including its own.
  • Listing memberships with user authentication lists memberships in spaces that the authenticated user has access to.
  • Listing memberships as a Google Workspace administrator with user authentication using administrator privileges lists memberships in all spaces in your Google Workspace organization.

The Membership resource represents whether a human user or Google Chat app is invited to, part of, or absent from a space.

List members in a space with user authentication

To list users, Google Groups, and Chat app in a space that the authenticated user has access to, pass the following in your request:

  • With user authentication, specify the chat.memberships.readonly or chat.memberships authorization scope.
  • Call the ListMemberships() method.
  • To list Google Groups, set the query parameter showGroups to true.

The following example lists Google Group, human, and app members visible to the authenticated user.

Node.js

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

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

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

  // Initialize request argument(s)
  const request = {
    // Replace SPACE_NAME here
    parent: 'spaces/SPACE_NAME',
    // Filter membership by type (HUMAN or BOT) or role (ROLE_MEMBER or
    // ROLE_MANAGER)
    filter: 'member.type = "HUMAN"'
  };

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

        # Number of results that will be returned at once
        page_size = 100
    )

To run this sample, replace SPACE_NAME with the ID from the space's name field. You can obtain the ID by calling the ListSpaces() method or from the space's URL.

The Google Chat API returns a list of Google Group, human, and app members from the specified space.

The following example lists human space members (not space managers) visible to the Chat app:

To run this sample, replace SPACE_NAME with the ID from the space's name field. You can obtain the ID by calling the ListSpaces() method or from the space's URL.

The Google Chat API returns a list of human space members (excluding space managers) from the specified space.

List members as a Google Workspace administrator

If you're a Google Workspace administrator, you can call the ListMemberships() method to list memberships for any space in your Google Workspace organization. The Chat API only returns memberships about users��both internal and external—or Google Groups from your organization, and therefore omits memberships for any Chat apps.

To call this method as a Google Workspace administrator, do the following:

  • Call the method using user authentication, and specify an authorization scope that supports calling the method using administrator privileges.
  • In your request, specify the following query parameters:
    • Set useAdminAccess to true.
    • To return only users, set the filter for member.type equal to HUMAN.
    • To return users and groups, set the filter for member.type not equal to BOT AND showGroups equal to true.

For more information and examples, see Manage Google Chat spaces as a Google Workspace administrator.

Customize pagination or filter the list

To list the memberships, pass the following query parameters to customize pagination of, or filter, listed memberships:

  • pageSize: The maximum number of memberships 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 more 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. Requires user authentication. For supported query details, see the ListMembershipsRequest reference.
