Question

API:https://graph.microsoft.com/v1.0/me/events
Request Body:{
"subject": "My event",
"start": {
"dateTime": "2021-07-08T04:46:05.073Z",
"timeZone": "UTC"
},
"end": {

Answer 1

It is not supported to create an event along with attachments within a single request, only we can post an attachment to the event after it's created.

We can use the following API to add an attachment to an existing event.

   POST /me/events/{eventid}/attachments  
     
   {  
     "@odata.type": "#microsoft.graph.fileAttachment",  
     "name": "$(fileName)",  
     "contentBytes": "$(base64EncodedString)"  
   }
