4.7.2 Updating the Callback Service Code
The following provides a sample of the callback service code. The code shown in bold illustrates how to extract the relatesToID from the message header, which is sent by the
client as the MessageID.
You need to implement the code to process the response and deploy the callback service as a Web service. Once deployed, add the URL of the callback service to the
client code as the replyTo field.
