For details, see [Extend Google Chat](https://developers.google.com/workspace/add-ons/chat). ## June 04, 2025 Breaking **Developer Preview:** Starting on June 16, 2025, the following default Apps Script function names for [Google Chat app triggers](https://developers.google.com/workspace/add-ons/chat/build#triggers) will change: - For **Added to space** triggers, the default function name will change from `onAddToSpace` to `onAddedToSpace`. - For **Removed from space** triggers, the default function name will change from `onRemoveFromSpace` to `onRemovedFromSpace`. If your Chat app responds to being added or removed from Chat spaces, you can address this breaking change and avoid any potential errors by doing one of the following: - In your Apps Script project, update the name of your functions to `onAddedToSpace` and `onRemovedFromSpace`. If required, [create another versioned deployment](https://developers.google.com/apps-script/guides/versions) of your Apps Script project and save the new deployment ID in the **Chat API Configuration** page in the Google Cloud console. - In the Google Cloud console, open the **Chat API Configuration page** and in the **Triggers** section, update the function name for the **Added to space** and **Removed from space** triggers so that they use the function name that you're currently using in your Apps Script project. To learn how to update your Chat app configuration in the Google Cloud console, see [Configure a Google Chat app](https://developers.google.com/workspace/add-ons/chat/configure). ## May 12, 2025 Deprecated For Google Workspace add-ons that extend Google Chat, the `invoked_function` field is no longer part of the [Common event object](https://developers.google.com/workspace/add-ons/concepts/event-objects#common_event_object). Use the `parameters` field to determine and handle user interactions. If your application doesn't depend on the `invoked_function` field, no action is needed. If your application used the `invoked_function` field, [see to the documentation](https://developers.google.com/workspace/add-ons/chat/collect-information#transfer) for an example that uses the `parameters` field to create interactive widgets. ## May 05, 2025 Feature **Generally Available**: Granular OAuth permissions are now supported for HTTP Google Workspace add-ons. The granular OAuth consent screen lets users specify which individual OAuth scopes they want to authorize. Keep the following dates in mind when you're building or modifying add-ons: - HTTP Google Workspace add-ons built after May 27, 2025 must support granular consent. - Existing add-ons have until December 1, 2025 to add support for granular consent. - After December 1, 2025, all HTTP Google Workspace add-ons must support granular consent. For more information about how to add support for granular consent, refer to [Build a Google Workspace add-on using HTTP endpoints](https://developers.google.com/workspace/add-ons/guides/alternate-runtimes#manage-granular). ## April 29, 2025 Fixed For Google Workspace add-ons that extend Google Chat, `event_time` timestamps are serialized and match the serialization of legacy Google Chat apps. You can now use the same timestamp-handling logic in both legacy Chat apps, and in your Workspace add-ons that extend Google Chat. Previously, timestamps were serialized in the following format: "eventTime": { "seconds": 1.742601948E9 "nanos": 7.01868E8 } After this fix, timestamps are serialized in the following format that shows the date and time: "eventTime": "2025-03-24T16:31:21.165203Z" [See the `Event` object in the Google Chat API](https://developers.google.com/workspace/chat/api/reference/rest/v1/Event). ## March 05, 2025 Feature **Generally available** : Chat apps can respond to quick commands.
