From body is null when sending XML to webapi controller

WebAPI

I am trying to send XML through postman to a WEB API Controller but in Controller, the model is always null. I searched a lot and did all the changes in WebAPIConfig but still stuck in the same issue.<br/>
Note
This project contains other controllers also and they are working fine. <br/>

What I have tried:

WebApiConfig

<pre>
config.MapHttpAttributeRoutes();
            config.Formatters.XmlFormatter.UseXmlSerializer = true;
            config.Routes.MapHttpRoute("DefaultApi", "api/{controller}/{id}", new
            {
                id = RouteParameter.Optional
            });

Controller

[HttpPost]
        public ResponseMessageResult CreatePayment([FromBody] Payment payment)
        {
        }

Model Class

public class Payment
    {
        public PaymentHeaderList[] Header { set; get; }
        public PaymentLineList[] Lines { set; get; }
    }

PaymentHeaderList and PaymentLineList classes are also defined below Payment class
