I created an app on https://apps.dev.microsoft.com
with the following Application Permissions:
Calendars.Read (Admin Only) Calendars.ReadWrite (Admin Only) User.Read.All (Admin Only)
Admin Consent
Admin consent was then successfully granted via this URL
https://login.microsoftonline.com/strixtechnology.onmicrosoft.com/adminconsent?client_id=bbb35336-faee-4c10-84b4-34136634db41&state=1234&redirect_uri=https%3A%2F%2Fdashmeetings.com%2Fmicrosoft%2Foauth
Get access token
An access token was then obtained from
POST https://login.microsoftonline.com/common/oauth2/v2.0/token
with headers
Content-Type=application/x-www-form-urlencoded
and body with key-value pairs
grant_type=client_credentials
client_id=bbb35336-faee-4c10-84b4-34136634db41
client_secret=xxx
scope=https://graph.microsoft.com/.default
This returns an access token.
Subscribe to notifications
Using that access token, I then try to subscribe to the events on a certain resource mailbox:
POST https://graph.microsoft.com/beta/subscriptions
with headers
Content-Type=application/json
Authorization=Bearer <access_token_here>
and body
{
"changeType": "created,updated,deleted",
"notificationUrl": "https://dashmeetings.com/microsoft/notify",
"resource": "users/mahogany@strixtechnology.com/events",
"expirationDateTime":"2017-12-01T11:00:00.0000000Z",
"clientState":"1234"
}
This returns a 401 Unauthorized with
{
"error": {
"code": "ExtensionError",
"message": "Operation: Create; Exception: [Status Code: Unauthorized; Reason: Unauthorized]",
"innerError": {
"request-id": "98ce5e5e-1ce4-4417-8c35-456a3cc0e696",
"date": "2017-11-30T10:59:28"
}
}
}
This question seems similar to “Resource not found for the segment” using Graph subscription beta, but I follow the same steps without any luck
