Send Microsoft Teams activity notifications without app manifest changes

Microsoft Teams activity notifications allow users to triage items that require attention. The activity notification APIs in Microsoft Graph can be used to extend this functionality to your apps, providing richer experiences and better user engagement.

Starting from November 6th, 2023, we are announcing the public preview of system default notifications. With this update, you can use the activity notification APIs without declaring the activities section in the manifest. The new system default notification allows you to send free-form text at runtime, eliminating the need to add, edit, or remove activityTypes in the manifest. You can find examples of sending customizable notifications and more information about using Graph APIs to send Activity notifications.

If you have any questions or need assistance, please reach out to our support team at https://developer.microsoft.com/graph/support. Thank you for utilizing Microsoft Teams!
