I am trying to us the Lifecycle events within the Graph Beta API using code like this:
var subscription = new Subscription
{
Resource = $"users/{userObjectId}/mailFolders('{resource}')/messages",
ChangeType = "created,updated",
NotificationUrl = notificationWebHookUrl,
LifecycleNotificationUrl = lifecycleNotificationWebHookUrl,
ClientState = clientState,
ExpirationDateTime = DateTime.UtcNow + new TimeSpan(0, 0, 4200, 0),
};
However, even though I have supplied a different LifecycleNotificationUrl to the NotificationUrl, the initial requests to perform the validate request only go to the NotificationUrl endpoint not the LifecycleNotificationUrl endpoint. I have checked and I am definitely supplying different endpoint urls. I am using 2 separate Azure Functions with Http triggers as the endpoints. Also to note is that I am using ngrok for exposing my localhost Azure functions. I understand that if you do not supply a LifecycleNotificationUrl that this is the behaviour that you should expect, but I am.
