    you postman setting make no sense.

    your post header say the body will be json, but in the body, instead of json you are using form-urlencoded.

    postman body editor is just a simple formatter. form url encoded is same as query string encoding:

    name1=value1&name2=value2

    the names and the values should be url encoded. if using a form post, then content-type header should be x-www-form-urlencoded

    note: it looks like an old postman. to send json. you should set the content-type=application/json and use raw body. enter valid json.

    seems odd you would use form encoded for an api, but its something like:

     var client = new HttpClient();  
     var data = new[]  
     {  
            new KeyValuePair<string, string>("username", "John Doe"),  
            new KeyValuePair<string, string>("email", "johndoe@example.com"),  
     };  
    var response = await  client.PostAsync(endPoint, new FormUrlEncodedContent(data));
