Twilio not sending status callbacks

Question

I'm trying to get status callbacks for various room events, but twilio is not sending any events to my callback URL, I've used the following code to create a room using the documentation i found here

app.get('/createRoom', function (req, res) {
    var client = new Twilio(twilioApiKey, twilioApiSecret, { 
          accountSid: twilioAccountSid 
    });
    client.video.rooms.create({
        uniqueName: myRoomName,
        statusCallback: 'myCallbackURL'
    }).then((room) => {
        //
    });
});
