Azure Function with Event Grid run local without ngrok

Question

I have an app that uses AzureFunction and EventGrid with Nodejs. I want to debug some Event Trigger Functions in localhost, but I don't want to use Ngrok, for particular reasons. There is another way to achieve EventGrid debugging without Ngrok?

Answer 1

When running Azure function locally, the EventGridTrigger can be access through this url:

http://localhost:7071/runtime/webhooks/EventGrid?functionName={functionname}

From Postman (for example), you would need these additional headers:

• Content-Type: application/json
• aeg-event-type: Notification

A full http request would looks like this

POST /runtime/webhooks/EventGrid?functionName={functionname}
Host: http://localhost:7071
Content-Type: application/json
aeg-event-type: Notification
