I have a scenario where I need to send the class object to the WCF REST method as input as given below .
[OperationContract]
        [WebInvoke(Method = "POST", UriTemplate = "/InsertContact", ResponseFormat = WebMessageFormat.Xml,
          RequestFormat = WebMessageFormat.Xml, BodyStyle = WebMessageBodyStyle.Wrapped)]
        int InsertContact(ContactType objContactType);
 
Getting the below error in the Fiddler

I want to make my REST API to accept either JSON or XML request depending on the client.Do I need to set this property in the WebInvoke attribute or in the web.config ?
Passing the below XML
<ContactType> <ContactTypeID>3</ContactTypeID> <Name>Assistant Sales Representative</Name> <ModifiedDate>2002-06-01T00:00:00</ModifiedDate> </ContactType>
Can anyone help me regarding this ?
