Not able to forward data from Azure Event Hub to HTTP Webhook using Azure Portal

Gaurav Kumar Garg 0

Dear Community,

I am facing issue with Event Subscription from Azure Event hub using Azure portal.

I think main problem is "Event- Hub" not sending event to the event grid topic.

I have created the subscription on this topic and forwarding to HTTP webhook endpoint. I even validated the URL that I received during creation of the subscription.

I can describe problem in detailed as following:

I have Azure Event hub where I am continuously receiving the data.

but I am not able to forward this data to HTTP endpoint.

I tried using event grid subscription to HTTP endpoint where I just want to forward whatever event I receive.

But these event Subscription not receiving any event from the event hub. and since its not receiving any event its not forwarding any event to HTTP Endpoint. (Please Note: While adding HTTP Webhook subscription I already verified the URL that i received during adding of event subscription)

Do you know what is going wrong here and why I am not able to forward data from Event hub to HTTP Endpoint using Azure portal.

Hello @Gaurav Kumar Garg,

welcome to this moderated Azure community forum.

I connected to a Webhook service recently and I had to confirm ownership using endpoint validation.

Have you checked if this step is needed for you too?

Dear @Sander van de Velde | MVP Thank you very much for your reply. I already did endpoint validation and its not working still.

Is there any documentation / Steps that i can perform to do this on Azure portal without any code ? Current documentation is very confusing / not enough for Azure portal.

Thank you.

Hello @Gaurav Kumar Garg,

I remember a specific text message with a URL proposal was sent and you need to perform a specific GET call to confirm you have received that text message.

I have not seen a CLI or coding solution by default but technically, this could be automated.

Regarding the suspicion that EventHub is not sending messages, this is interesting.

It seems the EventHub is delivering (outgoing) messages.

Are the Event subscription values still zero, or not defined?

If so, double-check the EventHub registration. Do you use the right EventHub? Do you have read rights for that EventHub? Do you use the correct consumer group?

Hello @Sander van de Velde | MVP , Eventhub receiving the message I can see in the traffic but I want to forward it to specific webhook HTTP endpoint which is not working. I even tried to use event grid and defined the event grid topic and did a subscription with event hub and output to webhook but it did not worked.

Hello @Gaurav Kumar Garg,

Technically it should be possible so it's probably the configuration...

It's hard to troubleshoot via this forum :-)

I suggest taking one step back and try these tutorials first.

If these work, your solution should work too, following the same steps.

Hi @Sander van de Velde | MVP , I agree technically its possible and at first place configuration also not that complicate but somehow first we don't have documentation for the configuration and if we have i am not sure if its up to date. For forwarding event from Azure Event Hub we simply need Event Grid topic and subscription for that topic with Event Hub and forwarding of data to Webhook, all these things correctly configured, but event grid topic not receiving data from event hub and since its not receiving data from event hub its not forwarding data webhook.
