Send custom events anywhere by using application topics to connect to Azure Event Grid. Application topics provide a SAS authenticated DNS entry point for custom events allowing you to leverage Azure Event Grid's deep integration with other services. You can subscribe to events in your Application Topic just as you would any native Azure resource.

Use Application Topics to:

• Send custom events to Azure Event Grid.
• Leverage Azure Event Grid to route and filter custom events.
• Subscribe to events in your application topic - private to you.
• Reliably delivery custom events to Azure or 3rd party services.
