Azure Event Grid can now publish events to endpoints protected by Azure Active Directory, automatically fetching tokens and using them to authenticate when sending events to your application's secured endpoints.
You can now simplify the way event-driven systems interact with the secured endpoints of your applications. This feature allows for simpler security management by enabling you to stop providing keys in query parameters and manually managing authentication (e.g. revoking access or rolling keys).
