Question 1

Question
Refer to the exhibits. In the requestFlow an HTTP Request operation is configured to send an HTTP request with an XML payload. The request is sent to the HTTP Listener in the transform Flow. That flow transforms the incoming payload into JSON format and returns the response to the HTTP request. The response of the request is stored in a target variable named the Result. What is the payload at the Logger component after the HTTP Request?
