Synapse custom event trigger publish is not happening on event grid with master branch

Madhu Challapalli 20

Hi all,

I have requirement to trigger synapse pipeline when I publish event on event grid.

Without git integration when I configure the Trigger and click on publish button, subscription is appearing on Event grid and trigger is working fine.

With git integration when I create a feature branch and configure trigger, I can't publish as publish button is disabled but can see the templates generated for tigger and pipeline in code.

When I merge code with master branch subscription is not reflecting on Event grid, I am not sure how to publish using git please help.

I tried to achieve it through azure cli but facing error - (Url validation) Webhook validation handshake failed for https://synapse.dev.azuresynapse.net/api/events. Http POST request failed with response code Unknown.

az eventgrid event-subscription create \
--source-resource-id "/subscriptions/subscriptionId/resourceGroups/ResourceGroup/providers/Microsoft.EventGrid/topics/EventGridTopic" \
--name eventgrd \
--endpoint-type webhook \
--endpoint "https://mysite.dev.azuresynapse.net/api/events" \
--included-event-types "CustomEvent"

Thanks for reaching out to Microsoft Q&A.

It seems like you’re facing a couple of issues with Azure Synapse and Event Grid integration. Here are a few suggestions :

Git Integration: When you’re using Git integration with Azure Synapse, the publish button is disabled because changes need to be committed and pushed through Git. The changes will be published when they are merged into the collaboration branch (usually the master branch). If the subscription is not reflecting on Event Grid after merging, it could be due to an issue with the publishing process from the master branch

Webhook Validation Error: The error message you’re seeing typically occurs when the service principal does not have the required roles or permissions, such as Microsoft.EventGrid/EventSubscriptions/Write, to perform the operation. You might need to be assigned the Event Grid Subscription Contributor role to manage event subscriptions. Please contact the owner of the subscription to assign this permission to your account.

Azure CLI Command: The Azure CLI command you’re using seems correct. However, make sure that the endpoint URL is correct and that it is accessible from the Event Grid. The error message suggests that there might be an issue with the URL validation.

Hope this helps. Do let us know If the problem persists
