test with & before sending replace & to & and test. url.Replace( "&" , "&" ) and then send and test.

Hi Sachin, Thanks for reply. I am getting same error. Problem is " & ks=7273996885894aef526d566605aeed67" which is part of url as query string. Im not sure how to overcome this.

test with this, your model class name must be same as in controller action services .AddMvc() .AddXmlSerializerFormatters(); [HttpPost] [Route( "cdr" )] public async Task int > CDACallback([FromBody]DocumentDto CDaCallbackModel) { } [XmlRoot(ElementName = "document" , Namespace = "" )] public class DocumentDto { [XmlElement(DataType = "string" , ElementName = "charge" )] public string charge { get ; set ; } [XmlElement(DataType = "string" , ElementName = "reason" )] public string reason{ get ; set ; } [XmlElement(DataType = "string" , ElementName = "hangup" )] public string hangup{ get ; set ; } [XmlElement(ElementName = "recording_url" )] public string recording_url{ get ; set ; } }
