c# - Getting the resource schedule from Office 365? -

i had python script fetch schedule resource(room) company's office 365 calendar calling https://outlook.office365.com/api/v1.0/users/<roomname@companyname.com>/calendarview?startdatetime=2016-08-07 22:00:00&enddatetime=2016-08-08 22:00:00

this doesn't seem work anymore? far find out looks api has changed restricting permissions resource calendar. correct assumption or doing wrong?

is there way schedule resource?

i preferably want in python or c#

what's error message get? if getting error the access token acquired using authentication method weak allow access application, need use certificate make request token instead of using client id , secret.

here code sample use certificate request token reference:

 public static async task<string> gettokenbycert(string clientid, string tenant, string certthumbprint,string resource)     {         string authority = $"https://login.windows.net/{tenant}";          x509certificate2 cert = certhelper.findcert(certthumbprint);         var certcred = new clientassertioncertificate(clientid, cert);         var authcontext = new microsoft.identitymodel.clients.activedirectory.authenticationcontext(authority);         authenticationresult result = null;         try         {             result = await authcontext.acquiretokenasync(resource, certcred);         }         catch (exception ex)         {         }          return result.accesstoken;     }
