Hi Preeti,
To access feedback use:
https://docs.mendix.com/apidocs-mxsdk/apidocs/feedback-api/
Use the status to select the right ones
And the Jira REST API is here:
https://developer.atlassian.com/server/jira/platform/jira-rest-api-examples/
It describes the Create Issue example
I would close the Feedback on Mendix side, so you will not create it twice.
Go Make IT
