My understanding of the API documentation is that the Statuses endpoint is used to update the Statuses available for use within Scale, e.g. I want to rename a custom Status that has the Name "Re-work" to "Backlog".
To update test results (which would contain the status of a result) you need to use the Test Executions endpoint, and you'll see that that endpoint does not have a POST endpoint. So unfortunately, the short answer is: you cannot update test results using the API - you can only create (or retrieve) them.
