Request.Form returns empty data

Question

I am working with two APIs. One is sending data and another one is receiving data, then do some work with it. Here is the code:

Sender API:

var campaignId = "1234";  
if (campaignId != null)
{
    using (var client = new HttpClient())
    {
        var httpContent = new StringContent(
            JsonConvert.SerializeObject(
                new { CampaignId = campaignId }),
            Encoding.UTF8,
            "application/json");  //also tried with application/x-www-form-urlencoded
            var uri = new StringBuilder(_domain)
                .Append("/api/mailchimp/campaign/send");
            var response = await client.PostAsync(uri.ToString(), httpContent);  
            ....  
            ....  
    }  
}

Receiver API:

var campaignId = HttpContext.Current.Request.Form["CampaignId"];  //also tried with Request.Params["CampaignId"] but here the Request.Form is always null

This technique always works for me when I serialize an object and then send it to the receiver API. But here there is only 1 variable (campaignId) so I don't want to use any model. Is there anything wrong with this syntax?

If you're using ASP.NET MVC, why are you using Request.Form? Why aren't you using the model binding? — mason, Jul 18 '18 at 14:24
@CodeCaster yes also tried with application/x-www-form-urlencoded — Wahid Masud, Jul 18 '18 at 14:26
@mason i dont want to create a separate class for only 1 variable. I already have a lot of models. So I was thinking maybe I could do an exception this time. — Wahid Masud, Jul 18 '18 at 14:29
for literally a single variable you don't need a whole new model, but your action method can still just accept `int parameterID` directly as an input parameter and MVC will do the rest, without having to look in the Request object directly. — ADyson, Jul 18 '18 at 14:31
You also can't post JSON as a form. That's still not a form. — CodeCaster, Jul 18 '18 at 14:32
ok so I need to use KeyValuePair. thanks for the suggestion. — Wahid Masud, Jul 18 '18 at 14:35
to use FormUrlEncodedContent(). see suggested duplicate question: https://stackoverflow.com/questions/20005355/how-to-post-data-using-httpclient — Wahid Masud, Jul 18 '18 at 18:13
