Integration with test management tool (other than qTest)

How can we integrate Katalon with other test management
tool like adaptavist and others?

How can we send execution result to other REST

How to extract execution result from Katalon
execution result?

As qTest is expensive and organization using several other
test management tool and doesn’t want to change legacy test management tool (which
provide REST API) very easily. So they might use standalone Selenium for
automation rather than Katalon.
