**For Community: **
In case someone wants to configure storage events to web hook endpoint then you can refer to this document which will help you how you can create the event grid subscription with the configuration.
When you configure the webhook endpoint then the first event that will be fired would be validation event. The azure infrastructure automatically handles this validation event only when you have configured the below services as the webhook endpoint.
- Azure Logic Apps with Event Grid Connector
- Azure Automation via webhook
- Azure Functions with Event Grid Trigger
In other webhook endpoint your endpoint code needs to participate in a validation handshake with Event Grid. In case if your endpoint doesn't respond with the validation response within 5 minutes then the event grid subscription creation will fail. For more details you can refer to this document.
When you are only looking for specific events to be delivered to the configured webhook endpoint then you can configure the filters so only specific events matching your filter condition should be sent to your configured webhook endpoint.
As you are only interested in the .xlsx file format events then you can leverage the subjectEndsWith
property with the value .xlsx
.
