WCF REST parameter object is null

Question

I have created WCF REST API. I have implemented following service interface and service method for the API.

service interface:

[OperationContract]
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Bare)]
ObjAPI GetAPIRequest(ObjAPI objAPI)

service :

public ObjAPI GetAPIRequest(ObjAPI objAPI)
{
   return new ExternalAPI().GetAPIRequest(objAPI);
                
}

code of ObjAPI class

    [System.Runtime.Serialization.DataContract(Namespace = "")]
    public class ObjAPI
    {
        [System.Runtime.Serialization.DataMember]        
        public int ID { get; set; }   

        [System.Runtime.Serialization.DataMember]
        public Client Client { get; set; }       


    }
}

My ObjAPI contain another object Client, then I have passed Following XML to the service.

<ObjAPI> 
<ID> 1 </ID>
<Client> 
< ClientNumber>0067HA000001</ ClientNumber>
</Client > 
</ ObjAPI >

But in the GetAPIRequest method, ID field is getting its value and client object become null.

How can I fix this Issue?

[System.Runtime.Serialization.DataContract(Namespace = "")] public class ObjAPI { [System.Runtime.Serialization.DataMember] public int ID { get; set; } [System.Runtime.Serialization.DataMember] public Client Client { get; set; } } } — Prasad

@Prasad - 1. Edit your question and add your code there, please. 2. Post the code for GetAPIRequest, as the issue may be there. — Tim

[ServiceContract]
public interface IInterface
{
    [OperationContract]
    [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Bare)]
    ObjAPI GetAPIRequest(ObjAPI objAPI)
}

public class Service: IInterface
{
    public ObjAPI GetAPIRequest(ObjAPI objAPI)
    {
       return new ExternalAPI().GetAPIRequest(objAPI);
    }
}

[System.Runtime.Serialization.DataContract(Namespace = "")]
public class ObjAPI
{
    [System.Runtime.Serialization.DataMember]        
    public int ID { get; set; }   

    [System.Runtime.Serialization.DataMember]
    public Client Client { get; set; }       
}

We also must set DataContract and DataMember attributes for Client class

[System.Runtime.Serialization.DataContract(Namespace = "")]
public class Client
{
    [System.Runtime.Serialization.DataMember]        
    public string ClientNumber { get; set; }     
}
