REST API - Test runs creation

Hello,

is it possible to create test run under test case  through REST API services?

I am able to do it - but only test runs under test set, like this:

POST:
projects/{project_id}/test-runs/create/test_set/{test_set_id}

and then

PUT:
projects/{project_id}/test-runs?end_date={end_date}

Thanks, Dara
