in short, when sending simple values which are to be picked up using [frombody] attribute on the server side, you have to prefix the value with = e.g. =testValue

but its probably better just to use JSON Objects and object bindings on the API, even for simple values

Answer 2

Do you always send the same parameters? If so, could you create a static object instead of using a dynamic one? Something like an EventRequest that you pass in instead?

public class EventRequest
{
    public int CheckinCount { get; set; }
    public int EventId { get; set; }
    public int OrderNo { get; set; }
}

Your Post action then becomes:

public IHttpActionResult Post(EventRequest request) {
    // do something with request
    return Ok();
}
