Use partner topics to connect third-party event sources (such as SaaS solutions) directly to Event Grid and subscribe to their events in the same way you subscribe to events from other Azure services, such as Azure Storage or IoT Hub.
The first partner integrated with Event Grid Partner Topics is Auth0. Connect your Auth0 and Azure accounts in order to react to, log, and monitor Auth0 events in real time.
Try it today by signing in to your Auth0 account and creating an Event Grid integration. You’ll see a pending Auth0 Topic in your Azure account. Click Activate, then create event subscriptions, and then route and filter your events just as you do any other event source.
Integrate your solution with Event Grid following the partner onboarding documentation
