Hi ,

I am able to create events using Graph API with https //graph.microsoft.com/v1.0/me/events endpoint.

However , some times it's returning 400 error.

Thanks,

Novel

We are not able to repro this issue. Could you please share the client request id and time stamp when you see this issue?

Hi Meghana, Even I couldn't reproduce the same error, it's only happening occasionally, but definitely there was an error, it happend on two different computers with different users. I will let you know if it’s happens again

Thanks

Kishore

Hi Koshore,

The 400 error means that you have a bad structure in what you are sending. Ensure that you are sending the require structure of JSON to the API endpoint.

It is very important to send consistent structure.

See examples:

H Dillon, Thanks for your reply. I have checked the code and there was no issue creating the event. This error only happening on randomly, same request working after few minutes.

var startDateTime = new Date();

                startDateTime.setMinutes(startDateTime.getMinutes() + 5);

                var endDateTime = new Date();

                endDateTime.setMinutes(startDateTime.getMinutes() + 30);

                $.ajax({                      

                    url: "https://graph.microsoft.com/v1.0/me/events",

                    data: JSON.stringify({

                        "subject": "Meeting",

                        "body": {

                            "contentType": "HTML",

                            "content": "Meeting"

                        },

                        "start": {

                            "dateTime": startDateTime,

                            "timeZone": "British Summer Time"

                        },

                        "end": {

                            "dateTime": endDateTime,

                            "timeZone": "British Summer Time"

                        },

                        "location": {

                            "displayName": "Micosoft Teams"

                        },

                        "attendees": [

                                },

                                "type": "required"

                            }

                        ],

                        "allowNewTimeProposals": true,

                        "isOnlineMeeting": true,

                        "onlineMeetingProvider": "teamsForBusiness"                         

                    }),

                    type: "POST",

                    headers: { "Authorization": "Bearer " + token },

                    contentType: 'application/json;charset=UTF-8',                      

                    success: function (data) {

                        if (data) {

                            var MeetingContent = `<h2>Microsoft Teams meeting </h2><p>Start Time: ${startDateTime}</p>

                                                  <p>End Time: ${endDateTime}</p>

                                                  <p> Join Url= ${data.onlineMeeting.joinUrl}</p>

                           //Microsoft Teams meeting  has been created

                        } else {

                           //Error in creating Meating

                        }

                    }
