“Resource not found for the segment” using Graph subscription beta

Question

Im using the Microsoft Graph to get calendar event with application permission. It works perfectly. Now Im trying to set up a subscription to listen to event changes however the normal v1.0 do not suport this. However beta, at least in the description, say it works.

From the page: https://graph.microsoft.io/en-us/docs/api-reference/beta/api/subscription_post_subscriptions

"Note: the /beta endpoint allows Application permissions as a preview feature for most resources."

So I tried this with the URL: https://graph.microsoft.com/beta/subscriptions

Sending in a json object like this:

{ "changeType":"created,updated,deleted", "notificationUrl":"https%3A%2F%2FXXX.com%2Fo365.php", "resource":"%2Fusers%2Fooom%40xxx.com%2Fevents", "clientState":"1486588355561", "expirationDateTime":"2018-11-20T18:23:45.9356913Z" }

Doing this I get the result:

{ "error": { "code": "BadRequest", "message": "Resource not found for the segment '/users/room@xxx.com/events'.", "innerError": { "request-id": "d9ca58b1-ee1f-4072-81d5-0f1a25dcdd45", "date": "2017-02-08T21:26:51" } } }

I have tried all types of combos in the resource but cant get it to work. Anybody that have an idea on how to do this?

The value of json properties don't need to be url encoded. The resource also doesn't need a '/' in front of "users" (although this isn't what is causing your issue).

Try changing your JSON to:

{ "changeType":"created,updated,deleted", "notificationUrl":"https://myurl.com/o365.php", "resource":"users/person@myemail.com/events", "clientState":"1486588355561", "expirationDateTime":"2018-11-20T18:23:45.9356913Z" }

Feel free to respond back if this doesn't address the issue.
