I am trying to use the API to create a calendar entry with Postman. I seem to be close receiving a 200 OK response, but still failing on a couple of things.
Here is some of the items...
Using JSON PUT request
http://confluence.(yourdomain).com/rest/calendar-services/1.0/calendar/events.json
Auth - Basic Auth - Use your user name and password
Header - Key: Content-Type Value: application/x-www-form-urlencoded
Body -
{
"subCalendarId": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx", "eventType":"Events",
"what": "Test Meeting",
"person": "(Your user ID)",
"startDate": "Oct 11, 2020",
"startTime": "10:00 AM",
"endDate": "Oct 11, 2020",
"endTime": "11:00 AM",
"allDayEvent": "false",
"where": "Test Room",} 
It looks like it is going to the right URL, but my fields might be incorrect. Anyone have any suggestions? I have tried digging through the internet and some of the python suggestions didn't seem to work either.
