Hi Johnson,
While Request/Response transformation policy is a great way to modify the request/response elements such as headers, query paramters, path parameters, HTTP methods, it doesn’t support modifying/dropping the request/response payload.
For modifying the payload you can use the “Invoke webMethods IS” policy or use the “webMethods IS Service” option under “Advanced Transformation” section of Request/Response transformation policies.
“Invoke webMethods IS” policy is in API Gateway since the beginning, but from version 10.2, the modification of elements such as headers, query parameters, path parameters, HTTP methods, payload etc, has become much more simpler.
Refer http://techcommunity.softwareag.com/pwiki/-/wiki/Main/Invoke%20webMethods%20IS%20policy%20in%20API%20Gateway%2010.2 for more details on this.
