When using Invoke API calls getting the default XML response. How Invoke API call can return JSON response instead of XML response?

For example, the call http://RegistryServerHostName:1505/api/Dcm/VSEs will return the below response in XML:

<?xml version="1.0" encoding="UTF-8"?>

Miss configuration of Response header.

Release : All Invoke API supported versions of DevTest

Component : CA Service Virtualization

Configuring the API request call http://RegistryServerHostName:1505/api/Dcm/VSEs with "Accept:application/vnd.ca.lisainvoke.virtualService+json" header element resolves the issue.
