How to find Event using the joinUrl

Question

My users create Calendar Invites (either via teams or outlook) and store the JoinUrl in a Sharepoint List for later reference.   My goal is to programmatically find the event that was created with this JoinUrl.

While I can easily locate the corresponding online meeting using graph api (filtering on JoinWebUrl), I haven't found a way to locate the corresponding Calendar Event.    I have tried variations of this with no success.

https://graph.microsoft.com/v1.0/users/{userid}/events?filter=onlineMeeting eq '{meeting join url}'
I know that joinUrl sit within onlineMeeting. I even recall, having receid an error messafge saying onlineMeeting cannot be searched. Any ideas to accomplish this task or better way to proceed are welcome !

Hi @Hariharan Rajkumar [external]

You can get the event set first, and then use that 'joinUrl' to filter the event set to get the target event.

For example:

try {

    var result = await graphClient.Users["{user id}"].Events.GetAsync();

    var joinUrl = "{joinUrl}";

    if (result != null && result.Value != null)
    {
        foreach (var events in result.Value)
        {
            if (events.OnlineMeeting != null && events.OnlineMeeting.JoinUrl != null && events.OnlineMeeting.JoinUrl.Equals(joinUrl))
            {
                Console.WriteLine(events.Id);
            }
        }
    }
    else
    {
        Console.WriteLine("No events found.");
    }

}

catch (ODataError odataError)
{
    Console.WriteLine(odataError.Error.Code);
    Console.WriteLine(odataError.Error.Message);


}

Hope this helps.

Answer 2

It is not possible to directly find a calendar event using the JoinWebUrl.

One way to find the calendar event is to search for the event in the user's calendar using the Microsoft Graph API and filter the results based on the subject, date, and time of the event. You can also try to search for the event in the user's calendar by looking for the JoinWebUrl in the event body.
