Azure Event Grid is a great technology for creating “push-push” asynchronous communication between resources in Azure. One of the benefits of such a “push-push” system is that it allows a consumer of events to remain stateless - no listener is required.

The Azure Portal allows for a fairly easy creation of subscriptions but ideally these subscriptions should be scripted and stored in source control.

Here we learn how to debug Azure Functions Event Grid triggers locally using Visual Studio and Postman.
