What’s changing Granular OAuth consent is rolling out over the next few weeks for Google Workspace add-ons built using HTTP endpoints. Granular consent gives users clear choices about the data they share with third-party applications.
This update is similar to an update made earlier this year with the introduction of granular OAuth consent in the Google Apps Script IDE : when someone installs or runs an HTTP Workspace add-on that supports granular consent, they will see a redesigned consent screen. Instead of being asked to authorize all requested permissions at once, users can selectively grant access to individual OAuth scopes.
For example, Google Workspace add-ons can extend to multiple Workspace apps, but users might only use an add-on for some of the apps it extends. With granular consent, users can choose to grant all permissions to an add-on or grant permissions as needed when they use the add-on in each app.
This screenshot shows the new OAuth consent screen, which lets the user provide consent for a subset of the requested OAuth scopes.
Additional details Following is the timeline for developers supporting granular consent in HTTP Google Workspace add-ons:
New 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.
After a user grants permission to a Google Workspace add-on that supports granular consent, the add-on might request OAuth consent again in the following cases:
The user, who has granted consent to a subset of the requested OAuth scopes, tries to run a part of the add-on that requires scopes that were not previously authorized. The add–on is updated in such a way that it requires permission for additional scopes. The user revoked access to the add-on from their Google Account settings .
This update does not apply to the following scenarios, for which granular consent may become available in the future:
When an admin initially installs an add-on When an admin updates the permissions granted to an add-on from the Admin console If a Google Workspace add-on is built in Apps Script
Getting Started Admins: There are no changes to the admin controls for this feature.Developers: For information about how to add support for granular consent to HTTP Workspace add-ons, refer to the developer documentation .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 add-ons they’ve already authorized.
