Granular OAuth consent in Google Chat apps

What’s changing
We recently announced that Chat apps built as Google Workspace add-ons using Apps Script would begin supporting a more granular OAuth consent screen this month. OAuth consent is needed by an app when the app is accessing user data or performing actions on a user’s behalf. With this new feature, users can now choose the specific data that the app can access.

Building on the previous update, we’re introducing this granular OAuth consent for all types of Chat apps using Apps Script, not just those built as Workspace add-ons, starting on January 20, 2026. Please refer to our developer documentation for more details.

Getting started

• Admins: There is no admin control for this feature.
• Developers and end users: This new consent screen will only be used for new OAuth scope grants. Pre-existing scope grants will not be affected, so no action is required by users on Chat apps they’ve already authorized. Developers should review the developer documentation to learn how to handle granular consent for Google Chat apps.

Rollout pace

• Rapid Release and Scheduled Release domains: Gradual rollout (up to 15 days for feature visibility) starting on January 20, 2026

Availability

• All Google Workspace customers, Workspace Individual subscribers, and users with personal Google accounts can use Chat apps
• All Google Workspace customers can develop Chat apps
