Zephyr Scale - How to specify test cycle in Junit report ?

I don't know if is possible to specify a test cycle, I post my json below, and when I send the request a new cycle is created:"Automated build"

Here the json(I appreciate if someone could write all the fields)

{
   "version": 1,
   "executions":[
      {
         "source":"Internal",
         "result":"Passed",
         "testCase": {
            "key": "QA-T196"
         }
      }
   ]
}
