When I step through the code and get the that line of code, hovering the mouse over PromoResult says that there is no object and that is where the program ends with the errors below. Not sure how to fix this. Any ideas?

>Probably cause is that you are accessing JsonResult before the ReadAsStringAsync() completes. Try:

var JsonResult = await response.Content.ReadAsStringAsync().Result;

I tried that and the IDE gave me an error. I do have an await in the GetAysnc call and I have verified stepping through the code that JsonResult is populated. PromoResult is defined here:

namespace m2m { 
    public class PromoResult {
        public PromotionObserver promotionObserver { get; set; }
    }
}

namespace m2m
{
    public class PromotionObserver
    {
        public int autocouponlinkpk { get; set; }
        public int subscriberfk { get; set; }
        public DateTime enddate { get; set; }
        public bool hidesharebutton { get; set; }
        public bool iscoupon { get; set; }
        public string coupdescrp { get; set; }
        public bool globalcoupon { get; set; }
        public string imageurl { get; set; }
        public string market_descrp { get; set; }
        public string globallogo { get; set; }

    }
}
