Receiving "Invalid 'changeType'" when subscribing to user created event

Question

I am trying to create a Webhook (aka Subscription) for users who are created, updated, or deleted in Office 365.

With the "changeType": "updated" it works fine but with "changeType": "created" it returns an error:

This is the request:

{
    "changeType": "created,updated,deleted",
    "notificationUrl": "https://ourLink",
    "resource": "users",
    "expirationDateTime": "2017-12-16T14:49:57Z",
    "clientState": "pe1g9gqiVsE6KnHTUuK9Tts3o660KOAw9YnavVfKhr22I7FlqC0tfMhpayxrqFP4orFPOjK0rppYtDicvxZosbvOEEgfy3YYoM3FGDwLQiW4MAdSCTdQkffuChjmB"
}

Error:

{
    "header": 400,
    "body": {
        "error": {
            "code": "InvalidRequest",
            "message": "Invalid 'changeType' attribute: 'created'.",
            "innerError": {
                "request-id": "74454900-d3df-4962-b58e-cfd7ec7454bc",
                "date": "2017-12-13T16:49:59"
            }
        }
    }
}

Creating a subscription to a user resource is only available in the Beta API but according to the documentation, it should work.

Answer 1

Based on the error message and that the User Webhook sample application only handles updated and deleted, this should be the expected behavior.

I'm also unable to find where in the documentation it states that a user resource accepts subscriptions for created. If you could provide a link I will make sure the documentation gets updated.
