I am not able to add a new WebHook subscription in the Azure Event Grid. Can someone help? I am getting below error when I add the webhook endpoint.
{
"status": "Failed",
"error": {
"code": "ResourceDeploymentFailure",
"message": "The resource operation completed with terminal provisioning state 'Failed'.",
"details": [
{
"code": "Url validation",
"message": "The attempt to validate the provided endpoint https://webapplication120180427035159.azurewebsites.net/api/values?id=AMif5RXS+Bs0bgsbHnNP8RUcn8ZacH8ETUzHXZ5YlNM= failed. For more details, visit https://aka.ms/esvalidation."
