This page contains release notes for features and updates to the Chat API. We recommend that Chat API developers periodically check this list for any new announcements. ## November 04, 2026 Feature **Developer Preview:** Google Chat apps can now stream messages incrementally using the [`spaces.streamMessages`](https://developers.google.com/workspace/chat/api/reference/rest/v1/spaces.streamMessages.md.txt) resource in the Google Chat API. Message streaming lets your Google Chat app display live progress indicators, intermediate reasoning or tool-execution steps, inline citations, and incremental text responses before committing a finalized message. Streaming supports the following methods on the `spaces.streamMessages` resource: - [`create`](https://developers.google.com/workspace/chat/api/reference/rest/v1/spaces.streamMessages/create.md.txt): Starts a new stream message in a threaded space. - [`appendStreamMessageContent`](https://developers.google.com/workspace/chat/api/reference/rest/v1/spaces.streamMessages/appendStreamMessageContent.md.txt): Appends text chunks, steps, inline citations, and updates progress text. - [`patch`](https://developers.google.com/workspace/chat/api/reference/rest/v1/spaces.streamMessages/patch.md.txt): Replaces streamed content chunks or updates progress text in place. - [`commit`](https://developers.google.com/workspace/chat/api/reference/rest/v1/spaces.streamMessages/commit.md.txt): Finalizes the stream into a permanent `Message` resource and attaches cards, accessory widgets, or footer sources. - [`delete`](https://developers.google.com/workspace/chat/api/reference/rest/v1/spaces.streamMessages/delete.md.txt): Discards an active stream without saving a message in the space. Users can also stop an active stream in Google Chat, which sends a `SYSTEM_COMMAND` interaction event containing `cancelStream` metadata to your Google Chat app. This feature is available as part of the [Google Workspace Developer Preview Program](https://developers.google.com/workspace/preview). For more information, see [Stream messages using the Google Chat API](https://developers.google.com/workspace/chat/stream-messages). ## November 03, 2026 Feature **Generally Available:** You can now add citations and footer sources to Google Chat text messages. You can provide sources in two ways: - **Inline citations**: Interactive cards that appear when users hold the pointer over specific parts of your message text. - **Footer sources**: A list of sources displayed at the bottom of the message as footer links. Citations are supported when the message's `markupSyntax` is set to `MARKUP_SYNTAX_MARKDOWN` and when messages are created asynchronously using the Google Chat API. For more information, see [Add citations to a text message](https://developers.google.com/workspace/chat/format-messages#messages-citations). ## October 30, 2026 Feature **Developer Preview:** You can now configure your Google Chat app to organize 1:1 direct messages with users into separate, thread-based conversation sessions by turning on **Enable Agentic features** on the Google Chat API **Configuration** page in the Google Cloud console. Using the Google Chat API, your app can also retrieve session details with [`spaces.threads.get`](https://developers.google.com/workspace/chat/api/reference/rest/v1/spaces.threads/get.md.txt), update session titles and icons with [`spaces.threads.patch`](https://developers.google.com/workspace/chat/api/reference/rest/v1/spaces.threads/patch.md.txt), and list sessions in a 1:1 direct message space with [`spaces.threads.list`](https://developers.google.com/workspace/chat/api/reference/rest/v1/spaces.threads/list.md.txt). For more information, see [Organize conversations into sessions](https://developers.google.com/workspace/chat/sessions). ## October 29, 2026 Feature **Generally Available:** Subscriptions to all Google Chat events in a Google Workspace organization, known as customer-level subscriptions, are now generally available. Using customer-level subscriptions, Google Chat apps can monitor space and user events across an entire Google Workspace organization without the app being a member of every space. Customer-level subscriptions support the following authorization scopes, which require service account configuration and administrator approval: - `https://www.googleapis.com/auth/chat.app.all.spaces.readonly`: To see space metadata. - `https://www.googleapis.com/auth/chat.app.all.memberships.readonly`: To see all space memberships. - `https://www.googleapis.com/auth/chat.app.all.messages.readonly`: To see all messages and reactions. - `https://www.googleapis.com/auth/chat.app.all.users.readstate.readonly`: To see read states of all users. To learn more, see [Subscribe to all Google Chat events in a Workspace organization](https://developers.google.com/workspace/events/guides/create-subscription.md.txt#customer-subscription) and [Customer subscription limitations and delivery behaviors](https://developers.google.com/workspace/events/guides/events-chat.md.txt#customer-limitations). ## October 23, 2026 Feature **Generally Available:** Chat apps can now create messages containing [cards](https://developers.google.com/workspace/chat/api/reference/rest/v1/cards) on behalf of users with [user authentication](https://developers.google.com/workspace/chat/authenticate-authorize-chat-user). Additionally, apps can asynchronously update cards in these messages without requiring user interaction using the [`replaceCards`](https://developers.google.com/workspace/chat/api/reference/rest/v1/spaces.messages/replaceCards.md.txt) method. For more information, see [Create and update interactive cards](https://developers.google.com/workspace/chat/create-update-interactive-cards). Feature **Developer Preview:** You can now programmatically read and update configurations for Google Chat apps (built as Google Workspace add-ons) using the `GetChatAppConfig` and `UpdateChatAppConfig` methods on the `chatAppConfig` resource in the Google Workspace Add-ons API. This feature is available as part of the [Google Workspace Developer Preview Program](https://developers.google.com/workspace/preview). For more information, see [Configure your Chat app using the Google Workspace Add-ons API](https://developers.google.com/workspace/chat/configure-chat-api#configure-api). ## October 16, 2026 Feature **Generally Available:** You can now configure an app-level default **Markup syntax** ---to use standard Markdown syntax or the original Google Chat syntax---on the Google Chat API **Configuration** page in the Google Cloud console, which starts to roll out today, with an expected completion in the next few days. You can also override the app-level default on individual API requests by specifying the `markupSyntax` field in the [`Message`](https://developers.google.com/workspace/chat/api/reference/rest/v1/spaces.messages.md.txt) resource when creating, updating, or reading Google Chat messages. For more information, see [Configure the Google Chat API](https://developers.google.com/workspace/chat/configure-chat-api#configure-console) and [Format messages](https://developers.google.com/workspace/chat/format-messages#format-texts). ## October 12, 2026 Announcement OAuth 2.0 clients calling the Google Chat Model Context Protocol (MCP) server are required to have **Use this client for an AI-powered agent** selected in **Google Auth Platform** **\>** **Clients**. Starting November 11, 2026, Google Workspace MCP servers will reject requests from any app or integration whose OAuth client is not marked as agentic by selecting **Use this client for an AI-powered agent**. OAuth clients that are not marked as agentic by November 12, 2026 will remain non-agentic and can't call Google Workspace MCP servers. To use MCP after this date, you will need to create a new OAuth client marked as agentic and update your app to use it. Apps and integrations that are not AI agents, like those that only call Google Workspace REST APIs, are not affected by this change. If an existing OAuth client is used for both AI agent and non-agent features, create a separate OAuth client for the AI agent and mark only that client as agentic. Keep the existing client for your non-agent features. The Google Chat MCP server is available as part of the [Developer Preview Program](https://developers.google.com/workspace/preview). For instructions on configuring an OAuth 2.0 client for the Google Chat MCP server, see [Set up the Google Chat MCP server](https://developers.google.com/workspace/chat/api/guides/configure-mcp-server#configure-mcp-client) and [Manage OAuth Clients](https://support.google.com/cloud/answer/15549257). ## September 30, 2026 Feature **Generally Available:** Google Workspace Add-ons that extend Google Chat now support **App Home** , letting you display a custom homepage card in the **Home** tab of a 1:1 direct message with your Chat app. You can configure an App Home trigger in the Google Cloud console and return a `RenderActions` object (using `pushCard` or `updateCard`) from an HTTP endpoint or Apps Script `onAppHome` callback function. For more information, see [Configure a homepage for Google Chat](https://developers.google.com/workspace/add-ons/concepts/homepages#chat-homepages) and [Receive and respond to user interactions](https://developers.google.com/workspace/add-ons/chat/build). ## September 28, 2026 Feature **Generally Available:** When using user authentication to call the Messages and Memberships APIs, the Google Chat API now populates user profile details (`displayName`, `email`, and `avatarUrl`) for both internal and external users. Profile details are populated for message senders, users mentioned in annotations, and space members, provided the user is a member of the space or has a prior affinity with the calling user. For more information, see [Identify and specify Google Chat users](https://developers.google.com/workspace/chat/identify-reference-users.md.txt) and the [`User` resource reference](https://developers.google.com/workspace/chat/api/reference/rest/v1/User.md.txt). ## September 23, 2026 Feature **Generally Available:** You can now configure who can view the list of members in a Google Chat space using the `accessSettings.accessPermissionSettings.viewSpaceMembershipSetting` field and the `permissionSettings.viewSpaceMembership` field on the `Space` resource in the Google Chat API. These fields let you define which target audiences in Google Workspace and which space roles can see the member list of a space. Requests that modify who can view space membership must include both fields in the `updateMask` and request body. For more information, see [Make a space discoverable to specific users in a Google Workspace organization](https://developers.google.com/workspace/chat/space-target-audience#make-space). ## September 18, 2026 Feature **Generally Available:** The Google Chat API endpoints targeting message pins are now Generally Available (GA) and are no longer restricted to the Developer Preview Program.

Feature **Generally available**: We're enhancing membership roles in Chat spaces by introducing a new membership role type. In the Chat UI, existing space managers are now owners and a new manager role is added. Previously, there were three membership role types in Chat API. `MEMBERSHIP_ROLE_UNSPECIFIED`, which meant a user wasn't a member but could be invited. `ROLE_MEMBER`, which meant a user was a member of the space. And `ROLE_MANAGER`, which meant a user was a space manager. Now, in the Chat UI, `ROLE_MANAGER` users are called owners; this is a cosmetic change so permissions and the API enum remain the same. To help space owners administer spaces, we're introducing `ROLE_ASSISTANT_MANAGER` which is called manager in the UI. Possible membership roles include: - `MEMBERSHIP_ROLE_UNSPECIFIED`: Default value. For users: they aren't a member of the space, but can be invited. For Google Groups: they're always assigned this role. - `ROLE_MEMBER`: A member of the space. In the Chat UI, this role is called **Member**. Members have basic permissions, like reading messages in a space. Managers and Owners can grant them additional permissions, like adding or removing members, editing space details, and turning history on and off. - `ROLE_ASSISTANT_MANAGER`: A space manager. In the Chat UI, this role is called **Manager**. By default, managers have permission to make other members managers, delete messages, and change space permissions. - `ROLE_MANAGER`: A space owner. In the Chat UI, this role is called **Owner**. Owners have the broadest set of permissions, including permission to make other members owners or delete the space. To learn more, see [Update a user's membership in a Google Chat space](https://developers.google.com/workspace/chat/update-members.md.txt) and [`MembershipRole`](https://developers.google.com//workspace/chat/api/reference/rest/v1/spaces.members#membershiprole) in the Chat API reference documentation. ## September 22, 2025 Announcement **Generally available** : You can now [format text with Markdown](https://developers.google.com/workspace/chat/format-messages.md.txt#markdown), including lists and code blocks, in your Chat apps. ## September 18, 2025 Feature **Developer Preview** : The following Chat API methods support [app authentication with administrator approval](https://developers.google.com/workspace/chat/authenticate-authorize-chat-app.md.txt) when called with `chat.app.*` authorization scopes: - [Get a Chat space event](https://developers.google.com/workspace/chat/get-space-event.md.txt#get-space-event-app-auth). - [List Chat space events](https://developers.google.com/workspace/chat/list-space-events.md.txt#list-space-events-app-auth).
