How to trigger an Event Grid from an IoT Central Rule?

Munaj Syed 21

I have a device that is connected to iot central and i've created some rules to be triggered. I currently have an azure function that is connected to the rule but i would like to use my event grid instead so that it hits the topic and my subscriptions can listen to it.

How would i be able to accomplish this?

Hi,

have a look at the Azure Event Grid output binding for Azure Functions document.

another alternative way is to use a CDE Webhook destination to fire the AEG Custom topic with a cloudevent schema and using the advanced filtering in the subscription.
Note, that the ce-id, ce-source, ce-specversion and ce-type headers must be added.

Thanks

Hi Roman, thanks for responding!

I was hoping to see if there was a way to do it directly in Iot central under the rules tab.

Hi,

there is no way to fire directly the AEG Custom Topic from the rule action (missing a capability for adding the custom headers at the webhook action).

However, like I have mentioned in my answer, the CDE Webhook destination has this capability included a telemetry and message property filtering and a custom message enrichment.

Thanks
