Create a Teams calendar event from a bot

Hi,

I have a nodejs bot running with my Teams app. I would link to add a new meeting event in Teams calendar, is it possible? I have read about 'schedules' in Graph API, but I am not sure if this is the key, since I can not see fields like startTime, duration, ...

Could you please help me?

Thanks in advance,

Diego

    Go to the Group you want the calendar for:
    Click “Calendar”:
    Copy the URL from your browser:
    Add a new tab within a Channel in Teams:
    Select “Website”:
    Add a name and the URL you copied from the Outlook Web App:
    Sign in to Microsoft when prompted.

      Nikitha-MSFT Thanks for your response.

       

      I have some doubts, please correct what I write below if required:

       

      As far as I understand, I can use Application permission to create an event, so I will access Graph without a user (https://docs.microsoft.com/en-us/graph/auth-v2-service)

       

      I will use 'POST /users/{id}/events', where the {id} must be Teams userId (what I get in 'activity.from.id' of an incoming command), and not the Office365/Azure id.

       

      'Bearer' header is required, so I need a token. I have running code to get Teams users, and previously I get a bearer token with this options:

       

      var options = {
          uri: 'https://login.microsoftonline.com/{tenant ID}/oauth2/v2.0/token',
          method: 'POST',
          headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
          body: 'client_id=' + {appId} + '&client_secret=' + {appPassword} + '&scope=https%3A%2F%2Fgraph.microsoft.com%2F.default&grant_type=client_credentials',
      };

       

      With the token received in the response, I can access to the users in a Teams group:
            https://graph.microsoft.com/v1.0/groups/{groupID}/members

       

      Can I use this token (for my application) to create an event for a user from the bot?

       

      With a userId = '29:184h5dKIrOfsVklZrZyWMe91Gio.....nNQiCqFNLreLIEq-YC' I have tried this PUT:
            https://graph.microsoft.com/v1.0/users/{userId}/calendar/events
            and the previous Authentication bearer token
            with an example event as body

       

      but I get a '500 Internal Server Error' as response.

       

      What am I doing wrong?

      Thanks a lot,

      Diego
