Parameter to update test case execution result in Zephy Scale API

I'm not a big use of the API but I'll give it a go.

For Cloud, I assume it's in the the 'POST Create test execution' endpoint, under the array for testScriptResults and StatusName: Zephyr Scale for Jira Cloud API (smartbear.com)

For Server, I assume it's in the /testresult enpdpoint: Zephyr Scale Server API (v1) (smartbear.com)
