Trying to post events to user calendars for our organization. Getting a 401 error.
Azure admins created an app/user, and gave permissions
Delegated Graph Permissions: Calendars.ReadWrite
App graph permissions: Calendars.ReadWrite
I can connect to the OAuth token generation end point, and retrieve a token. Using that token, I can't send my JSON payload and create a series of calendar events, I get a 401. The JSON is known good - I can copy/paste it into the graph explorer tool and get correct results.
I've examined a generated token using jwt.ms and I'm not seeing anything related to permissions, calendars, etc.
Our Azure logins use empIDnumber@example.com and I've been told that is what our userPrincipalName is
I've tried changing the URL end point with no change-
/v1.0/users/empIDnumber@example.com/calendar/events
and
/v1.0/users/empIDnumber@examplecom.onmicrosoft.com/calendar/events
Where should I look next?
Solved.
Slight typo in the content of the JSON I was sending, was only able to find it by doing the POST using postman. Java was throwing an exception, not showing the returned string as well as the exception message, but postman showed the returned JSON with content regarding malformed date/time.
Still got 401 exceptions though, so The Fix Part II was to add an Accept-Encoding property set to application/json to my http client request options array.
Still no claims showing up in my tokens, but that is a non-issue apparently.
